Centrifugal Slurry Pump

Our Product

Put yourself in the driver’s seat with the revolutionary new Warman® WBH® centrifugal slurry pump.

Solar-powered water pumps are ideal for irrigating rice fields, watering gardens, supplying drinking water, and filling livestock ponds.

There would be few people involved in slurry pumping who wouldn’t be familiar with the Warman® AH™ slurry pump and the many innovative enhancements and material improvements which Weir Minerals has developed to meet the productivity and cost demands of customers in all types of operating environments.

This development has extended over four decades, providing Weir Minerals with a vast knowledge bank in slurry pumping technology. So by putting our heads together on a global basis, by understanding the needs of customers today, and by the aid of Computational Fluid Dynamics design, Weir Minerals has created the ultimate slurry pump – one that

Maintenance magic with a fully adjustable throatbush while running.

The days of uneven and premature wear that result in disrupted production will become a thing of the past with this quantum leap in front liner design. With just a single action you can now adjust the throatbush front liner both rotationally and axially, and at the same time. The new WBH® slurry pump puts you in the driver’s seat when it comes to minimising the wear in the front liner because you can adjust the throatbush to close the clearance between it and the impeller. All in all, you’ll be well ahead, as you can now maintain the pump’s performance and efficiency close to that of a pump in new condition, and reduce wear from a single point of adjustment.

A whole list of advances from wet end to drive end.

A single-action fully adjustable throatbush might seem enough on its own in making maintenance easier, but Weir Minerals did not stop there in creating the new WBH® slurry pump. Weir Minerals looked at every aspect of maintenance ease, operating cost and safety, and this work resulted in a whole list of advancements from the front liner to the drive end. For example, with the WBH® pump, there is no need to check or readjust the drive every time an adjustment is made like with the AHTM pump.

A giant step forward in power savings

As the cost of power and carbon reduction becomes increasingly critical to your business, the new WBH® slurry pump is designed to make big inroads in cost reduction for you. By keeping the gap between the impeller and throatbush minimised with the fully adjustable throatbush, having a drive end that keeps aligned to the front liner, creating a shaft and casing that stays aligned to extend the life of mechanical seals, and having an integral (one-piece) bearing frame and a new concept in impeller and volute design, you’ll have your power costs not only well under control, but well down.

Wear life under your control

Computational Fluid Dynamics methods played a vital role in the development of the WBH® slurry pump’s wear resistant features. When you adjust your throatbush while running with a single action whenever you want, you’ll be spreading the throatbush wear more evenly, extending its life. The unique new impeller and volute design minimises turbulence so that wear becomes more predictable. And with a robust one-piece bearing frame for accurate alignment, it will keep your bearings going longer.

Smoothing the flow of slurry

Considered a revolution in impeller and volute design, the new WBH® slurry pump replaces the uneven wearing of the past caused by unwanted vortices with a unique patented design based on a vanelet in each impeller channel, and a four-vane impeller as standard to streamline the slurry flow through the pump. No longer impeded by the need to stop production or ramp up speed to catch up because of these vortices between the impeller and volute, power usage, maintenance costs and pump performance will follow a smoother path.

Keeping the pressure up

The ability to withstand the demands of high pressure wherever it is faced in the slurry pump flow has been incorporated into the new WBH® slurry pump design right down to the smallest detail. Beginning with the biggest advancement of them all, the drive end has a strong and rigid one-piece bearing frame to keep the bearings aligned all the way through to the front liner, minimising vibrations and distortions from external piping loads.

Then there are the large capacity bearings that mean you can handle high loads including thrust and endure the test of time. The bearing end cover seals are a commercial labyrinth style that both seal out the dirt and slurry and keep in the lubrication. Gone is the need for the regular bearing labyrinth grease purging used on the AHTM pumps.

In the front liner, There’s a large diameter Warman Hi-Seal® -style expeller as an option for sealing against high intake pressures without gland seal water. All rubber and metal liners are high pressure rated with rubber liners encapsulated within to prevent liner extrusion or blow-out.

The new Warman® WBH® centrifugal slurry pump gives you greater control over the performance, maintenance and safety of your pump.
