Automatic Lubricators

2

Harnessing cutting-edge technology to deliver improved pump lubrication and maintenance efficiency.

The key to ensuring your Warman® centrifugal slurry pump is maintained to the best possible standard is an automatic Accumin™ lubricator.

Accumin™ lubricators automatically deliver even, measured lubricant to the vital points of your Warman® pump. This results in enhanced availability and durability.

Accumin™ lubricators are designed to ensure the correct lubricant dosage is safely applied on a consistent basis. This reduces the need for manual labour and helps to prevent unplanned downtime.

In addition to Warman® pumps, the Accumin™ lubrication system is also available for use on valves. It is ideal for use on Isogate® knifegate valves to ensure consistent and even lubrication of the gate.

The Accumin™ system can also be used for the lubrication of mechanical seals and it is suitable for most grease-lubricated rotating equipment such as Multiflo®, Hazleton®, Lewis® and GEHO® pumps and Aspir™ centrifuges.

Our Accumin™ lubricators are designed to: • Improve pump and valve reliability •H elp prevent unplanned downtime and reduce maintenance costs • Reduce demand on manual labour • I ncrease personnel safety by reducing the time spent in hard-to-access and potentially dangerous areas Accumin™ automatic lubricators come in four sizes and two drive configurations, ensuring they are ideal for use in a variety of situations.

Accumin™ lubricators are available in premium or standard grease types ensuring maximum flexibility.

Accumin™ premium lubricant

Accumin™ standard lubricant

• A premium lithium-complex thickened grease with a synthetic lubricating fluid recommended for arduous duties.

Provides superior resistance to the degradation of lubrication property and ensures its extended service life.

• A high-quality, lithium-complex thickened grease recommended for use in harsh conditions.

• Fully compatible with the lithium-based greases, Accumin™ premium can be used in existing pumps without needing to replace existing grease.

• Accumin™ premium is specified and recommended for use in heavy-duty applications, as per the Warman® pump installation and operating manual.

• Accumin™ premium has been specifically selected for Warman® centrifugal slurry pumps for optimal performance in mineral, coal and industrial processing.

• Designed to provide high adhesion and resistance to water contamination.

• Provides excellent lubrication, however Weir Minerals recommends Accumin™ premium for superior pump performance and protection.

Reliability and productivity The benefits of applying small amounts of grease at short-time intervals to your equipment include increased reliability and productivity.

Accumin™ lubricators can be supplied with specific lubricants suitable for equipment such as electric motors, centrifuges, mechanical seals, and conveyor pulley bearings.

For higher-speed pump applications and electric motors, the addition of small amounts of grease at short-time intervals is particularly beneficial in helping to prevent over-lubrication which can occur if large amounts of grease are quickly introduced to the bearings.

For equipment such as conveyor pulley seals, the regular addition of small amounts of grease develops a grease-purging effect through the seals in order to assist with the prevention of contaminant entry.

Above: Overgreasing of pump bearings is a common problem. It causes overheating and bearing failure.

Accumin™ Lubricator 125 A self-contained waterproof system with a simple-to-use rotating dial setting system, and clearly visible grease lubricant piston.

The fully assembled Accumin™ lubricator 125 is ready to use straight out of the box.

Once set, the self-contained unit supplies a continuous level of fresh lubricant directly to the lubrication point. It is dustproof and waterproof (IP68), making it ideal for use in harsh operating conditions.

Key features • The 125cm3 capacity canister has an electronically controlled gas generation system that can be set to a time period between one and twelve months.

Above: The dial system on the top of the Accumin™ lubricator 125 is easy to use and can be altered at any time.

• The Accumin™ lubricator 125 can be turned off and on, if required, and the dispensing rate can be easily adjusted by simply turning the dial to a new time setting.

• The amount of lubricant remaining in the Accumin™ lubricator 125 can be quickly assessed via visual inspection of the lubricant piston position.

• Consistent lubrication where and when it is needed can help prolong the life and enhance the efficiency of your Warman® pump or your rotating equipment.

Dispensing rate options Time settings are available in monthly increments from one through to twelve months. The table below provides the daily dispensing rates for the standard monthly settings.

Accumin™ Lubricator 120 & Accumin™ Lubricator 250 Featuring an electro-mechanical drive for precise grease delivery, display screen and LED system for immediate status recognition.

Both the Accumin™ lubricator 120 and 250 include a replaceable lubricant cartridge fitted to a reusable drive unit. The electromechanically driven lubricator dispenses a consistent dosage of lubricant, regardless of ambient temperature.

Maintenance of the Accumin™ lubrication system has been made as simple as possible. The status of the lubricator can be determined by the LCD display, flashing LED alert system, an on-cartridge recording system, and the clear cartridge that shows the percentage of lubricant remaining.

Key features • 120cm3 and 250cm3 capacity canisters have battery-powered mechanical drive systems that deliver measured volumes of lubricant at precise intervals.

Top: The LCD display of the Accumin™ lubricator 120 and 250 provides immediate confirmation of the operational status of the lubrication system.

Bottom: The light system utilises red and green LEDs to indicate the general status of the lubrication. This is especially useful when installed in areas with poor light. Red indicates that action is necessary.

• Consistent lubrication where and when it is needed can help prolong the life and enhance the efficiency of your Warman® pump and other rotating equipment.

• Both Accumin™ lubrication systems can be installed up to five metres away from the lubrication point, allowing easy and efficient access to the mounting point.

Dispensing rate options Time settings are available in monthly increments from one through to twelve months. The table below provides the daily dispensing rates for the standard monthly time settings. The system also provides an option for weekly settings up to a maximum of 24 weeks with an alternative drive unit.

• The lubricant dispensing rate can be easily adjusted and turned off at any time via simple push-button operation on top of the drive unit without the need to disassemble any part of the lubricator.

Accumin™ Lubricator 500 Designed for larger applications with higher grease rate demand.

The reusable electro-mechanical drive unit of the Accumin™ lubricator 500 dispenses a consistent dosage of lubricant from the replaceable cartridge at set periods. A combination of smart features makes it easy to check the status of the Accumin™ lubricator 500. A transparent lubricant cartridge, flashing LED alert system and LCD screen displaying the status (run, purge, empty, etc) of the lubricator are clearly visible to the maintenance personnel on site.

The light system utilises red and green LEDs to indicate the general status of the lubrication. This is especially useful when installed in areas with poor light. Red indicates that action is necessary.

Designed to be remotely mounted, installation kits for the Accumin™ lubricator 500 provide practical solutions for installation at safe and easy-to-reach locations, such as attaching to beam sections and square cage safety mesh.

Key features • Battery-powered mechanical drive system delivers measured volumes of lubricant at precise intervals.

• With a push of the button on top of the drive unit, the lubricant dispensing rate can be easily adjusted and turned off at any time.

•C onsistent lubrication where and when it is needed can help prolong the life and enhance the efficiency of your Warman® pump and other rotating equipment.

• For easy access to the mounting point, the Accumin™ lubricator 500 can be installed up to five metres away from the lubrication point.
