The compression is performed by a ring of liquid formed as a result of the relative eccentricity between the pump’s casing & a rotating multi bladed impeller. The eccentricity results in near complete filling then partial emptying of each rotor chamber during every revolution. The filing –and- emptying action creates a piston action within each set of rotor impeller blades/ fins. The pump’s components are positioned in such a manner as to admit gas when the rotor chamber is emptying the liquid, and then to allow the gas to discharge once compression is complete.

This often poses a challenge for end-users. These pulsations can not only be harmful to the pumped product but they also place a particularly high load on the installed equipment. Depending on the intensity, this can lead to hammering noises or vibrating pipes and hoses.
These pulsations are particularly harmful to any downstream sensor technology, such as pressure or flow sensors. It also makes a repeatable dosing and filling process complicated.
The maintenance-free pulsation dampener is manufactured by Tapflo in plastic PE & PTFE as well as in stainless steel, polished stainless steel and aluminium. The high-performance diaphragms made of PTFE, EPDM, NBR and other are characterized by a particularly long service life due to their sandwich design and integrated metal

Due to the "inline" design, the liquid can be pumped without additional pressure losses, shear impacts and product impairments. This is a decisive advantage, especially for share sensitive liquids, viscous liquids or liquids with a high concentration of solids. It should also be noted that reduced pressure fluctuations reduce the pressure losses in the pipeline and thus the delivery
Very high priority is also put on the protection of expensive and fragile instruments installed in modern production and supply pipelines. By using a Tapflo pulsation dampener, the use of a flow meter and its correct functioning is often made possible.

rate is increased. "Active pulsation dampener" - The Tapflo pulsation dampener actively collaborates with the pulsating flow of the pumped liquid. Due to the supply of compressed air, which is taken from the pump air inlet, there is the same pressure in the pulsation dampener as in the pump. If the pressure between the pump strokes in the pipeline drops, the dampener provides additional pressure on the pumped fluid. Which reduces or prevents the Furthermore,pulsation.
One of the biggest challenges when using positive displacement pumps are the pressure variations on the discharge side. Depending on the functional principle, these effects are larger or smaller, but they are always present.

Atlas Copco’s new range of GHS VSD+ vacuum pumps offer intelligent networking of vacuum pump and process
Building on the revolutionary GHS VSD+ range of variable speeddriven oil-injected screw vacuum pumps, Atlas Copco have taken a leap ahead with the new GHS 14022002 VSD+ series. These series of pumps have a new design for better performance, optimal oil separation, a smaller footprint and an innovative new controller which puts the customer in gear for Industry 4.0.
Compared to the previous models, the innovative design of the three models GHS 1402, GHS 1602 and GHS 2002 VSD+ results in better vacuum performance, a 15 percent smaller footprint and longer maintenance intervals.
With the GHS 1402 - 2002 VSD+, vacuum manufacturer Atlas Copco is launching a new model of speed-driven screw pumps in three pumping speed classes. In rough vacuum applications, the oil-injected pumps deliver a continuously high pumping speed - from atmospheric pressure to ultimate pressure.
8 Pipes, Pumps and Valves Africa May/Jun 2022
“The footprint of the GHS 1402-2002 VSD+ is smaller than 2 square meters. The design is compact due to the vertical drive train design,” commented Vanderveken.
The new GHS VSD+ screw pump also contributes significantly to saving energy costs. This is based on the one hand, on the combination of the Neos inverter with a setpoint control.
High efficiencies at all speeds and demand levels
This means that the GHS 14022002 VSD+ deliver exactly the pumping speed required for the respective process.
Moreover, an energy recovery system helps recover up to 80 percent of the power in the form of hot water. In addition to saving costs and water, this also results in lower CO2 emissions.
This makes them ideal for use in central vacuum systems, for vacuum cooling, for the production of food packaging

Competitors are feeling the heat from the hard-working Grindex Bravo 600 submersible slurry pump, which has replaced under-performing products at two mine sites in Limpopo and North West provinces recently.
The Grindex Bravo 600, though, has proven ideal for these applications, being supplied in South Africa as standard with a glycol-filled cooling jacket to keep its temperature down. This allows it to function reliably even when exposed above the slurry level.
“Plant operators are not always able to be present to check the levels in these tanks, or to add water to dilute slurry, so the specific gravity of the material can rise considerably,” he says. “This is where the Grindex Bravo 600’s agitator comes into its own, agitating the solids into suspension for easier removal. It even handles particle sizes up to 40 mm.”
Bravo pump pushes out contenders in dense slurry work
Integrated Pump Technology has been distributing Grindex pumps in sub-Saharan Africa since 2014. So confident is the company about these advanced workhorse pumps, that the company offers a 30 month warranty on the units. Its well-equipped engineering facility in Jet Park undertakes maintenance and repairs to OEM standards.

The attraction, according to Jordan Marsh, sales manager at Integrated Pump Technology, has been the Grindex Bravo 600’s reliability and efficiency. This is due largely to its innovative cooling jacket between the outer casing and the “Minesmotor.have a frequent requirement for a hard-working pump to transfer slurry from process tanks, where levels change quickly and the material often becomes quite viscous,” says Marsh. “In these dry-bed applications, many pumps struggle with the density or even burn out when no longer submerged.”
To demonstrate the pump’s performance under these arduous conditions, Integrated Pump Rental offers mines a trial unit to run over an extended period. These tests are now resulting in purchases, says Marsh, after the customer is satisfied that the pump delivers. Both the impeller and casing are manufactured from hard iron, making for a robust product with long working life.

The GRM will also send a notification to Grundfos and the customer when the pre-determined service intervals have been reached, ensuring that regular maintenance is conducted to optimise pump longevity and performance.
“This gives us the opportunity to order in the necessary spares, to have them available as soon as the customer’s
There is even an element of remote control in the GRM, which allows the user to manage the equipment – for instance, stopping and starting the pumps – without having to physically stand in front of the machinery, she notes. This can help to avoid catastrophic failure from conditions like dry running.
The result, according to Nicolette Gomes, senior service sales specialist at Grundfos, is that users have the ability to assess their equipment performance at all times – and to plan for the necessary servicing interventions.
“We facilitate this process with our Grundfos Remote Management (GRM) system, which is a cloud-based portal that users can log in to from anywhere,” says Gomes. “The required module just has to be installed onto a pump controller we can even install GRM on other pump brands, after updating the controller on their system.”

The success of IPR is rooted in its evolution from just renting diesel-driven dewatering pumps to designing and manufacturing fit-for-purpose solutions that are reliable and cost effective.
He notes that off-the-shelf products often only serve the customer’s best-case scenario, and will fail to deliver the
This approach has developed a large customer base in all sectors, from mining and construction to wastewater and general industry. He highlights that each dewatering application has its own specific requirements, including the volume of water that needs to be pumped and the quality and composition of the water. The presence of particles or larger solids, for instance, will affect the choice and specification of the pump. During an assessment of a customer’s operational requirements, the pump set’s materials of construction will also be considered, to deal with the prevailing level of water acidity and abrasiveness.
16 Pipes, Pumps and Valves Africa - May/Jun 2022
According to Lee Vine, managing director of IPR, the traditional approach in the pump rental sector has been ‘take it or leave it’ – which does not address the specific needs of individual customers and applications.
“Learning from the many diverse applications that we encountered when starting out in the pump rental business, we built a depth of experience in mine dewatering – especially in the surface mining sector,” says Vine. “This informed how we developed our in-house engineering capability, so that we could offer customers bespoke solutions to meet their exact needs.”
The company also has longstanding customers who were unable to source dewatering pump sets within a short lead time, so instea,d they opted not to rent and rather to procure their own pump sets. With its field experience, technical expertise and modern workshop, IPR can meet this need, by designing and building pump sets engineered specifically to suit the application. Its support services ensure that parts are readily available, and that regular maintenance can be conducted to ensure optimal uptime.

expected duty when conditions are more arduous. Also, customers will frequently need an urgent solution in the short term, but in the longer term must look for a design that is more sustainable. “At IPR, we respond to short, medium and long term requirements,” Vine says. “Our responsiveness and extensive fleet allow us to quickly install an urgent dewatering system, after which we can work with the customer to engineer a lasting solution.”

“There is also the flow rate and maximum head to be considered, as well as the mobility requirements –determining whether we should consider a skid-mounted or trailer-mounted design,” he says.
“The solid performance of our team and our solutions is demonstrated by the fact that many customers who have asked for custom-built pump sets have previously rented pumps from us,” says Vine. “They were so impressed with the performance and reliability of our units, that they have taken the next step and acquired their own assets.”

In the United States alone there are an estimated 14 748 wastewater treatment plants where up to 90% of the work is performed with pumps.
According to Ortiz, VFDs with dedicated anti-clogging functions can help mitigate the issue through techniques
Pump clogging remains a serious problem, especially in water/wastewater applications. It can – and does - have huge financial repercussions. Reports are showing that during the Covid pandemic a serious increase was seen in nondispersible materials such as disinfectant wipes and the like in wastewater treatment systems.
“It is estimated that the water and wastewater treatment sector is the third-largest energy-consuming sector in the United States with critical processes in water, wastewater and irrigation activities jointly using more than 55 billion kilowatt-hours per year,” said Ruben Ortiz, Product Marketing Manager for Variable Frequency Drives (VFDs) at Mitsubishi Electric Automation. “It is estimated that North American businesses and households spent some $2.5 billion on personal wipes in 2019. It is further estimated that non-dispersible wipes result in about $441 million a year in additional operating costs at US clean water
contractors have indicated a nearly 40% increase in calls for clogged pipes and sewer pump systems because Covid 19 saw people’s increased use of wipes that are often carelessly flushed down the toilet instead of being thrown in the garbage.

Why are pumps still clogging? With more people comes the demand for more water and more treatment and wastewater facilities. But more people also come with more rags and clog-causing material that gets into these systems.
22 Pipes, Pumps and Valves Africa - May/Jun 2022
Applying a VFD
Prevention is better than a cure
This increased amount of non-dispersible materials in the system has contributed to pump lockup in wastewater facilities around the world.
This manual process – be it preventing the clogging or removing the clogs - is not only time-consuming but also very costly. “In the worst-case scenarios pumps have to be completely disassembled to address the clogging or even completely replaced.”
Ortizutilities.says
“Clogging is not new. It has been a problem for municipalities dealing with wastewater around the world for many years. Finding a solution has, however, been challenging,” he said during a recent online event. “More often than not the problem is dealt with manually meaning either the pumps are monitored manually to avoid any debris getting stuck in the pump. This sees pumps having to periodically be cleaned out to avoid any form of clogging happening or then they are monitored once the performance is affected and checked for any clogs and then cleaned after it has clogged.”
“More so, it drastically cuts down on clogging and increases pump life. The pump cleaning function can also be scheduled to operate during off-peak hours, so it doesn’t interrupt the normal pumping operation.”
“This solution not only reduces the number of hours spent dealing with the issue freeing up necessary manpower but also addresses the increased costs involved.”
The VFD cleaning features use a programmable timing sequence of forward and reverse rotations of the pump to get rid of and remove non-dispersible materials from the impeller. Different methods are available to trigger the function and start the sequence, said Ortiz.
power consumption is another benefit as the pump will use less than 20% in energy and pumps will also operate at a higher efficiency. It reduces manual labour and endless time monitoring pumps.”
“Applying a VFD saw them going from supervising their system daily to no supervision and no clogging occurrences,” he said. “The drive was now monitoring itself
such as forward/reverse time-sequencing to reduce manhours and avoid equipment failure.
Ortiz said screening processes are also not a safeguard for pump clogging. “These processes only collect and remove large floating objects from incoming wastewater. The best solution is to prevent clogging from the get-go ensuring that it does not happen at all. This approach is far more efficient and cost-effective in the long run.”
Other factors that play a role include how fast one wants the motor to go into reverse and then for how long.

Using a case study of a client Ortiz explained how the pump user was seeing clogging happening anything from four to nine times a week and how valuable time was spent checking on the pumps every day.
Materials that cause clogging in the wastewater system are not only wipes but also paper towels, napkins, baby diapers and toilet seat covers are a problem.
“The period between these reverse rotations as well as the length of time the pump is in reverse is dependent on the circumstances the pump is operating in. The only requirement is that the pump must be able to go into reverse and pump users should check this with their pump manufacturers before implementing such an anti-clogging solution.”
and clogs were simply no longer an issue. The company saved on maintenance and staff could focus on other tasks instead of supervising a pump.”
“You have to know the systems and what kind of materials go through because one has to programme according to that,” said Ortiz who says that annual maintenance cost savings of up to 60% can be made with an anti-clogging

Slurry gate valves, on the other hand, are bi-directional and typically elastomer seated. Some of the bi-directional valves like shear gate valves have a “preferred” flow direction, though they provide bi-directional shut-off.
You don’t see valves mounted upside down often, but in this way mounting knife gate and slurry valves could avoid sedimentation/settling/hardening at the bottom of the valve body. However, it may not be feasible as piping layouts do not usually allow such mounting but is a clever technique to use where space permits.

valves in sizes 250mm (10 inch) or larger.
Mounting is not usually important for valves carrying clean media but needs some attention in the case of KSG valves. While most of the models can be mounted in any orientation, some orientations are preferred (Fig-2).
Typically, knife gate valves are available in two versions: uni-directional or bi-directional. Uni-directional valves provide shut-off only in one direction; bi-directional valves provide same in both directions as in the case of most other valves. They may also be metal or soft seated.
Slurry valves also come in many design variants: pushthrough seal, perimeter seal, shear gate, o-port, rotating disc to name a few. For use in the guidelines, the most widely used knife- and slurry gate valve types are listed. These would be pictorially represented as shown in Fig-1 (it is assumed that the reader is familiar with these valves and their characteristics; for those who are not, an earlier article titled “Knife Gate & Slurry Gate Valves – A Review” published in Valve World, Dec-2019 could be useful).

A preferred orientation is one that minimizes chances of obstruction to movement of gate by any possible settlement of media. Also, any mounting orientation other than vertical usually needs additional supports, typically for
are often selected when the media handled is not clean. This also involves the selection of a particular design that is best suited for an application. The proper choice of type provides for optimum costs and trouble-free operation. This article looks at typical general application situations and attempts to provide guidelines on the most appropriate type of valve to be used.Valve
Usage scenarios: pump isolation
Usage of knife and slurry gate
KSG valves are designed for on/off duty and as such applications involving these valves are typically for isolation of pumps, pipelines, vessels, silos et cetera. An insignificantly small number is also employed for throttling or control application with some modifications. We will discuss these in the following sections. A typical pump uses a suction valve to isolate the pump from the sump and another on the discharge to isolate from the pipeline it is pumping to. Typically, two scenarios are possible in the first, the discharge pipeline goes straight to the sump, through vessels, equipment etc. of course. In the second case multiple pumps discharge to a manifold and / or interconnected discharge piping as shown (Fig-3). As can be noted, the valve at the pump suction sees flow only in one direction and a uni-directional valve can be used in such a location. Of course, a bi-directional valve can be used here as well. On the discharge side, a uni-directional valve can be used in the case of a single discharge line; but for interconnected discharge, a bi-directional valve must be used as it can be subjected to reverse pressure when shut.

Buried pipelines
“Excerpted from the article of the same title by S.Vijayakrishnan published in Valve World, Oct/Nov, 2021 issue.”
Valves are also used in pipelines for one of two purposes: to isolate a section of the pipeline or to divert the flow from one to another. Generally, the selection of valves is straight forward and primarily made to suit the media and its condition. However, in the case of KSG valves, few additional factors need to be considered. One is not to use uni-directional knife gate valves at a location where flow direction may be reversed for operational reasons. Another aspect stems from the type of media that these valves usually are used for, such as slurries, sludges, and the like. Care should be taken to see that the chances of media settling around the valve and possibly dewatering should be avoided. This will involve proper selection of flow direction, pipeline layout and gradients involved. Some typical guidelines are shown in the sketches here (Fig-4,5). Location of the valve at dead ends of pipelines need to take into consideration the body style of the valve. Many KSG valves have wafer, flangeless bodies and as such are difficult (and inadvisable) to mount on dead end pipe flanges. Also, the shut-off pressure capabilities may be lower than full rating when mounted between pipeline sections, and manufacturer’s recommendations need to be considered for same.
Silo isolation
Pipes, Pumps and Valves Africa - May/Jun 2022 29 VALVES
Material cut-off
Handling powders in silos and hoppers is a major usage area for knife gate valves. These applications takes advantage of their ability to cut through powders and close. In general, the valve should close against a moving column of powder for proper functioning. They are not designed to close against a stagnant column of material, especially when dense and tightly packed (Fig-8). Typically, isolation valves are required at two locations: as a feed valve at silo inlet and as discharge valve from silo outlet. Large majority of applications involve silos where the powder is fed or discharged by gravity flow. These applications only require the valves to be ‘powder tight’ and in such cases, uni-directional metal seated valves are used. Often it is recommended to mount them in the reverse flow orientation as it avoids material build up on seat which faces away from powder flow.
Pipeline isolation
Another situation is usage in buried pipelines. Most of the KSG valves have bonnet less OS & Y designs and they cannot be used for buried service. Few models are offered by manufacturers with bonnets, and those need to be selected for such applications. Often stem extensions are also used (Fig-6). Bonneted versions of knife gate valves are also selected when even small amount of gland packing leakage is objectionable. Many sewage treatment plants prefer to use bonneted knife gate valves for better containment of media. Double block and bleed isolation is not a common requirement where these valves are used. However, it may be desirable in some cases, for example, in some mine site pipe layouts that are modified regularly as in tailing disposal (Fig-7). Push-through seal slurry valves with their twin seat sealing and body drain provision can
When the silo is pressurized or kept under vacuum for process or conveying needs, the usage of valves would be different. Often a material cut-off valve (typically a unidirectional knife gate valve, reverse mounted) is used with another tight sealing valve below it as a combination. The tight sealing valve could be a dome valve, a butterfly valve or even a bi-directional soft seated gate valve. Another aspect to be considered for silo discharge valves is whether they are discharging to atmospheric pressure or to other equipment downstream such as a screw conveyor. In the latter case, the valve may be required to close against a stagnant powder column in an upset situation (say, when a downstream screw conveyor malfunctions).

A total water treatment programme should address any impurities in the source water (pre-treatment), the water treatment itself (filtration and / or chemical treatment) and ongoing testing and maintenance.
She says that in boiler operations, poor water quality results in poor quality steam. Feedwater must therefore be pre-treated. The aim is to remove impurities to control deposition, carryover, and corrosion in the boiler system, which affect the boiler’s effectiveness and, in the long run, can cause costly down time and unplanned repairs.
Managing water treatment “life cycle” saves costs and headaches
“Impurities will depend on the source (municipal, borehole, river or dam), and the geographical area, among other things. Specific water treatment processes will vary depending on the requirements of the system (cooling / heating) and the quality/chemistry of the feed and/or circulation water.”
“Within cooling towers’ makeup water, we focus on the water-replacing bleed, and evaporated and leaked water from the cooling tower,” says Hough. “If makeup water is not treated in cooling towers, we almost always see scale and corrosion taking place, which decrease the efficiency of the system.”
“Raw water sources contain varying amounts of suspended and dissolved impurities,” says Hough.
Allmech is a leading South African manufacturer of boilers and supplier of water treatment components, and Hough says that the company often sees cases where costs or downtime could have been reduced by implementing a proper water treatment plan.
The selection of pre-treatment option depends upon the quality of the water source, chemical characteristics of the water, the quantity of make-up feed water required, plant operating practices, etc.

“One of the best ways to stay on top of the health of your
Most cooling and heating system failures happen because of the same mistakes or oversights. Anelia Hough, water treatment consultant at Allmech, says that in boilers and cooling towers, these issues include skimping on water pre-treatment or on ongoing maintenance.
After-treatment involves the addition of chemicals. Specific chemicals must be used depending on the application. For example, Allmech offers a range of SANS 1827 food-grade chemicals for boilers, which are safe for food, beverage, pharmaceutical and agricultural uses. For cooling towers, the company supplies chemicals that act as scale and corrosion inhibitors (for open and closed systems), micro biocides, dispersants and cleaning agents.
Effective water treatment requires treatment before and after introduction of water into the boiler or cooling tower.
“Companies often select not to do water treatment, including pre-filtration, on their cooling and heating systems to reduce operating costs and to meet production demands. This, however, often has the opposite effect and the company might land up losing money. Skipping water treatment doesn’t just result in higher energy costs; customers risk a complete boiler or cooling tower shut down or replacement. That’s far more costly than the initial water treatment equipment and monthly water treatment services.”
Maintenance and testing
“There are four common problems that can occur in boilers and cooling towers that damage effectiveness: corrosion, fouling, biological contamination, and scaling,” she says.
Stages of water treatment
“Allmech focuses on each client’s individual boiler or cooling tower needs to ensure the best pre-water treatment and chemical water treatment solutions are offered. Our technologies, custom-engineered water treatment plants and cutting-edge solutions for boiler and cooling tower water treatment needs have been developed by helping our customers solve some of the most complex water treatment issues in the industry for over 25 years.
For example, Allmech ensures operators are maintaining their cooling and heating systems correctly and regularly by completing water treatment checklists and logs during the monthly water treatment services they provide.

It appears that more has been said than done about meeting South Africa’s water challenges; with the 2030 timeframe for meeting the Sustainable Development Goals (SDGs) looming, the country needs a new urgency on its water stewardship responsibilities.
She highlighted the importance of raising awareness about what water stewardship really involves: using water in a way that is socially and culturally equitable,
“We are far from meeting the SDG water goals, which target the availability and sustainable management of water and sanitation for all,” said Sutton. “Many companies highlight water issues in their policies, but do not seem to have taken the vital steps toward implementation of more sustainable practices.”
This is the view of SRK Consulting principal consultant Fiona Sutton, who has urged businesses to take a more proactive approach to achieve water sustainability in their operations and supply chains. The United Nations Industrial Development Organization (Unido) has forecast that global freshwater demand will be 6,900 km3 per year by 2030 –some 40% over the global sustainable fresh water supply of 4,200 km3 per year1- if current water practices continue.
“With growing populations and economies, changing lifestyles and global climate change, there is increased pressure on our water resources,” she said. “The private sector, government and other players urgently need to play their part and collaborate to ensure shared water security.”
She noted water crises are being exacerbated by climate change and are now acknowledged as societal risks due to their far-reaching consequences.
Sutton emphasised that the advantages of good water stewardship were substantial and included gaining efficiencies that allowed corporate initiatives to pay for themselves over time.
By incorporating local stakeholders in these initiatives the knock on effects of good water stewardship will benefit society as a whole and can contribute to corporate ratings on the environment, social and governance (ESG) criteria.
Practical steps and guidance in the AWS Standard help water users to improve their water practices for better onsite water performance, while also contributing to wider sustainability goals.
As a trained AWS water steward, she is equipped to help clients achieve AWS certification and to improve corporate systems.
“The AWS Standard offers a credible and globallyapplicable framework for major water users to understand their own water use and impacts with practical guidance on how to effectively manage these impacts,” she said. “Part of the solution is for companies to work collaboratively and transparently with others, most importantly the local communities, for sustainable water management within the context of their wider water catchment.”
“Taking effective steps in this direction gives businesses a competitive advantage and boosts their brand value –while assuring investors that the enterprise is viable for the long term.”
By building relationships with local water-related stakeholders, companies can enhance the positive impact of their initiatives and also help address challenges shared by others in the catchment, said Sutton.
“The journey starts with an understanding of the business’s water dependencies and impacts and develops to allow the mitigation of operational and supply chain water risks,” she said.

businesses, as these employees may be more likely to become infected, thereby needing to take sick leave or worse still bringing the virus into the workplace.” The Covid-19 pandemic will pass but water challenges related to climate change and associated drought and flooding risks will be with us a lot longer.
To make practical progress on their water stewardship journey, Sutton urged the use of global best practice tools like the International Water Stewardship Standard from the Alliance for Water Stewardship (AWS).
For those struggling to remove excess, standing water in hard-to-reach places like basements and bedrooms, Johan Kruger, Husqvarna South Africa's National Sales Manager offers some sage advice. "Being prepared is half the victory. So, regardless of whether you have a water-logged room from this recent hundred-year flood or if you just want to be better prepared for a future plumbing malfunction, there are six steps to getting the water out as soon as possible."
Step 2: Ensure that you put on protective gear like gumboots and rubber gloves if possible.
Johan shares the 6 important steps to remove excess water from your flood-damaged home/building:

The current floods and threat of yet more rain to come has left many folks across KZN and Eastern Cape overwhelmed and anxious. Some flood victims are homeless, whilst others, a week later, are still dealing with water-logged buildings and businesses.
Step 4: Remove the loose furniture, and wooden items first. Most wood, but particularly reconstituted wood products (like chipboard or laminated wood) swell when they come into contact with water. Place these in a dry spot.
There are bigger units that can obviously take on bigger volumes and distances. If you have no use for a water pump other than to pump out the excess water, consider hiring one from hire outlets like Talisman.

Step 6: To dry the floors and walls you can use heaters, fans or even a
• Once the water is out, the cleaning can start. If a lot of debris and soil came in with the water, this will be a manual process. If flooring, like carpets, has to be removed anyway, consider loosening them around the edges and rolling the dirt up in them; thereby removing the dirt and damaged flooring simultaneously. Remember to keep taking pics in case your Insurer asks for evidence. Consider washing the walls and floors with a disinfectant to combat any nasties that could have come in with the water.

Step 5: If the water has not been able to drain out of the affected spaces, it should be removed as quickly as possible. Husqvarna water pumps are perfect for this and are affordable and easy to use. In fact, the entry-level
Step 1: The first thing to do is turn off (and disconnect if possible) electricity points that are affected BEFORE you go anywhere near the water. The risk of electrocution is real.
Step 3: Take a few pics; these may be required by insurance. Document the source of the flooding i.e.: where the water came in, as well as what was affected e.g.: furnishings and floor coverings.
• Using the pump is as simple as putting the inlet pipe in the water and the outlet pipe where you want the water to go. Remember to prime the pump by opening the small cap on top of the pump housing and pouring water into it. Make sure there’s fuel in the tank (they are all incredibly fuel-efficient) and start.

This year’s event brought renewable energy, sustainable mining practices, community impact and ESG imperatives into focus. It also highlighted the value of Veolia’s solutions in addressing the environmental impact of the mining sector.
When the AngloGold Ashanti Obuasi Mine in Ghana was re-developed, it had to meet the specific requirements set out by the Ghana Environmental Protection Agency before it was awarded an operating licence. The mine contracted Veolia to supply a solution for the mine’s wastewater management, including both water for operations and drinking water for personnel. Veolia implemented a multiphase solution that included the overall management and treatment of water from ore processing. This has ensured that discharges comply with the requirements of the Ghana Environmental Protection Agency, enabling the mine to retain its operating license and carry out its core activities. In addition, the deployment of the solution in three phases made it possible to control the water treatment system and identify the optimisations necessary to better meet the mine’s needs.
In line with its Impact 2023 vision for the development of more innovative, efficient and sustainable solutions for the mining segment, Veolia Services Southern Africa attended the recent 2022 Mining Indaba.
“For emissions that cannot yet be reduced, the Veolia Group occasionally performs offsetting on behalf of clients. We are also working on tomorrow’s solutions, such as CO2
capture and its sequestration, even its recycling,” explains Veolia Services Southern Africa Business Development Manager, Reinier Delport

Speaking during a recent online event he said anyone relying on vibration to monitor the seal health of their pumps or trying to detect seal failure this way would inevitably come up short. “Vibration alone cannot do it. Four critical data points have to be measured – surface vibration, surface temperature, operating temperature and operating pressure using cloud-based analytics.”
Much has been said about digital and the cloud. According to Ryan Zepp, a sales director at A.W. Chesterton, it is important to understand the Return of Investment on the Industrial Internet of Things (IIot).
“The difference between the Internet of Things (IoT) and IIoT is that the convenience of the first drive, while the latter drives revenue.”
Value of IIOT for condition monitoring
In conjunction with monitoring vibration, is the only efficient way to address sealing device failure - the leading cause of pump downtime.
Real-time collection of pump operating pressure and temperature data
He said pump operators wanting to move from their current state to a future state needed to go through a transition impact of investment into new capabilities and technologies in condition monitoring. “It is only then that one will see an impact on revenue, costs and maintenance activities,” he explained. “During the investment period expect revenue to drop but as time goes on there will be a definite increase in revenue, and improved manpower and equipment utilization. The same goes for cost. Initially expect the cost to rise, but again, over time, it will come down with a real reduction in maintenance costs and all downtime of the equipment.”
40 Pipes, Pumps and Valves Africa - May/Jun 2022
Zepp maintains the number one value using IIOT lies in the ability for remote monitoring. “It does not matter whether
According to Zepp, cloud-based pump system condition monitoring, which associates process operating parameters with vibration, can notify users of current and potential causes of downtime and increase equipment reliability along with improving safety.
“It is all about being able to identify pump system anomalies and prevent unplanned events related to sealing devices and pump efficiency. It is about being able to drive revenue through condition monitoring.”
It also allows for a proactive approach rather than always being reactive. Thanks to the ability to detect anomalies early downtime is significantly reduced.
At the same time because it requires less human intervention than all walk-throughs and less downtime and maintenance it significantly improves manpower utilisation by prioritizing and addressing the assets systematically. “During a shutdown, for example, it allows for the assets that need to be focused on to get attention.”
“Seal failure also happens over a very short period versus bearing failure. When one is collecting data, for example, every 30 seconds with the gateway in the cloud, those very early signs of failure can be picked up long before it becomes a problem.”
“Bearings can be monitored through vibration alone, but seals are not bearings just as pumps are not motors.”
Pipes, Pumps and Valves Africa - May/Jun 2022 41 NEWSINDUSTRY
Addressing the cause
He says it is important to therefore not just monitor vibration alone as it is simply not addressing the largest cause of pump downtime.
The training element is important, says Zepp. “With the rate of skilled labour retiring training opportunities are important. It is estimated between 25 to 30% of skilled labour will be retiring in the next seven to 10 years with little or no backfill in those positions. Also, those positions that are being filled are not done with people who have the experience of those that left. We need tools for these new employees to bridge the experience gap.”
“Seals can fail due to process pressure and temperature variations triggered by changes in suction and discharge due to flow restrictions or valve regulation,” says Zapp.
A.W. www.chesterton.cominfo@chesterton.com,Chesterton,
one is monitoring from an office desk or home, as long as there is an internet connection, condition monitoring can take place remotely ensuring the ability to see what is occurring in the assets.”
Zapp says this type of condition monitoring increases equipment reliability ultimately prolonging the life of the pump, the bearings and the seals saving cost and revenue.
Another benefit is that when data is collected 24/7 across pumps, it delivers a business the ability to compare equipment performance. “One can overlie or correlate data from different assets to see if they running on the same curve making sure that all of the pumps are functioning optimally.”
It furthermore reduces human error. “Walk-throughs are inconsistent and infrequent. When continuous condition monitoring is done on a 24/7 basis, it eliminates exactly this. There is also a collection of data 24/7 which in turn removes the need for fingerpointing of what caused what issue when an error has occurred and it creates an opportunity for training.”
“To efficiently address the issue, it is important to monitor operating temperature and operating pressure in conjunction with vibration to detect potential misoperation and failure of seals.”
“It also increases safety,” he says. “It goes back to remote monitoring because if you are monitoring from an office the risks of manual walk-throughs are eliminated.”
Research has shown that seals are the most common component to fail in a pump causing at least 69% of all failures followed by the second most common component bearings responsible only for some 10% of failures.
“By having a notification system in place any anomalies can be detected meaning incidents are completely prevented as any kind of failure or problem that can cause machine downtime is prohibited. It is simply picked up before it even happens.”
More to see and do at Electra Mining Africa, celebrating 50 years this year
The Report also indicates an optimistic outlook for the exhibition industry; data from the barometer backs this up. Says Monica Lee Muller, President of UFI - The Global Association of the Exhibition Industry: “the Barometer results highlight the accelerating pace of the industry’s recovery in 2022, following the severe impact of COVID still felt on activities in 2021. There is strong anticipation that the sector, primarily driven by physical exhibitions and business events, will bounce back quickly.”
Electra Mining Africa is a much needed platform for buyers and sellers to connect face-to-face again. It presents an opportunity for industry networking to take place, to build business partnerships and new connections, and for new products and services to be launched.
Electra Mining Africa and co-located shows Elenex Africa, Powerex, Transport Expo and Automation Expo will be supported by a programme of content-rich conferences including SAIMC, WiMSA Women in Mining Workshop and

Electra Mining Africa and its line-up of conferences and free-to-attend seminars will be taking place from 5-9 September at the Expo Centre, Nasrec, in Johannesburg. Hundreds of exhibitors are ready to showcase their latest innovations, technology, products and services at Southern Africa’s biggest mining, electrical, automation, manufacturing, power and transport trade exhibition.
Entries are open for all operators who have a valid Forklift license and can drive either a reach truck or a counterbalance Forklift Truck in racking. The focus of the competition is on accurate, safe driving skills and knowledge, not on speed. The first round of heats for counterbalanced forklift operation will be an online test to assess entrants’ practical skills, theoretical knowledge, attitude and efficiency. Lifting Africa and LEEASA want to assist in promoting the importance of inspection, safety and training and to reward the safest forklift drivers at Electra Mining Africa.
Followingconfirmed.global trends, exhibitions are adopting more technology and moving to hybrid events. Whereas exhibitions remain a face-to-face, in-person event, technology can make the exhibition experience even more enjoyable, driving many aspects of the exhibition from registration to live streaming of events. What is clear from the February 2022 UFI Global Exhibition Barometer Report is that the majority of respondents agree that virtual events will not be replacing physical events.
This year, Specialised Exhibitions, organisers of the show, are promising an exciting interactive event with many activities planned by exhibitors and industry partners, and to also celebrate the show’s 50th anniversary.
