COVER STORY

A case for peristaltic pumps

South African pump manufacturer Afromix has designed and developed a robust pumping solution delivering exceptional performance the world over. Pipes Pumps & Valves Africa sat down with managing director, Eugene Els, to find out more.

Peristaltic pumps are a fast-growing market. Valued globally at around $315,5 million dollars in 2015, it is expected to reach $501,1 million by the end of 2023, representing an average compound growth rate of 6,87%. The low maintenance cost, seal-less design and corrosionresistant properties of these pumps are big drivers of the growth in the global market. According to Els there is a definite increase in demand from the various end-use industries. “Peristaltic pumps are incredibly robust,” he says while explaining that this type of pump is ideal for use of any contamination-free pumping of shear sensitive fluids or viscous sludge or slurries. Peristaltic tube pumps are also used for dispensing, metering, and transfer of aggressive and neutral fluids. “These pumps are designed to be a robust pumping solution for high viscosity, high solids that are very abrasive, high density slurries and liquids and are used in a wide array of applications and industries including mining, chemical, food and beverage, pulp and paper, petrochemical, pharmaceutical, agricultural, water treatment and many more.” Afromix took the decision to develop its own range of peristaltic hose pumps several years ago. According to Els the design process was not rushed and it took several years before the pump was launched. “There were several benefits to manufacturing our own pump,” he says. “Not only did it afford us the opportunity to develop and build a pump to suit our direct needs, but also to meet our stringent quality requirements.” At the same time it introduced a more constant work load and allowed the company to start an inhouse CNC machining facility which has allowed it to further expand its manufacturing capabilities. It has also led to increased

upskilling of staff. “Having one’s own production facility directly translates into increased training and apprentice programmes. That in turn ensures a more educated and experienced staff across our business as people are moving up and through the ranks steadfastly. For the end-user this is extremely beneficial as they are in contact with people who have intimate knowledge of the pumps at all contact points with the company.” Niche market According to Els whilst pumps only compromise some 20% of Afromix’s current business it is a sector within the company that continues to go from strength to strength. “We have seen phenomenal growth in our pumps since we first launched our product range some five years ago. We continue to drive that growth focussed on both the domestic and international markets.” He says this is thanks to the ongoing investment into research and development of products. “The AFX pump series, which was specially adapted to further improve the product’s high performance, durability and low maintenance, has continued to deliver exceptional performance, but what sets this pump apart from its competitors is its cost-effectiveness and reliable operation.” He says the pump demonstrates measurable savings over that of its competitors, including energy savings and maintenance downtime savings of up to 50% compared to traditional peristaltic hose pumps. The pumps are selfpriming, fully reversible, highly durable, easy to maintain, can be run dry for extended periods without damage, and offer flow rates from 40 l/ hr to 150 000 l/hr. “Our range also includes one of the largest pumps of this type in the world,” he says. The 150mm pump has a maximum flow rate of 150m³/ hr and can deliver pressures up to 15 Bar. These units, says Els, are ideal for thicker underflow applications. “This offering is a niche in the market. From a local perspective our manufacturing capability allows us to be very price competitive, while we are able to perform highly
