Tough, efficient medium-duty slurry pumps

Key benefits of our medium-duty pumps

Low cost-per-tonne pumped Designed to maintain constant operating speeds and reduce the impact of wear on operations, KREBS medium-duty pumps maintain hydraulic performance close to BEP throughout their life. The result is reduced energy consumption and maintenance requirements for a low average lifetime cost-per-tonne pumped.

Extend wear life Easy control of suction-side clearance in millMAX-e and slurryMAX pumps maintains hydraulic performance through the pump's life, increasing the wear life of wet-end components. Meanwhile, hMAX pumps’ concentric casing eliminates radial loads, extending the life of pumps, seals, and bearings.

Optimise pump liner performance With multiple, easily interchangeable elastomers, high-chrome alloys, and polyurethane combinations available, we have the wear material for any application. Using process data to understand your slurry, we tailor your liners to the application to deliver even, predictable wear and enable optimised maintenance scheduling to reduce downtime and inventory.

Our medium-duty pumps

hMAX slurry pumps millMAX-e medium-duty pump slurryMAX slurry pumps

hMAX slurry pumps

Suitable for applications where tramp material, product degradation, or entrained air can affect pump performance, the hMAX slurry pump features a recessed impeller and large internal clearances within a heavy-duty concentric casing.

Minimise product degradation. Reduced risk of air locking. Large solids passing size.

millMAX-e medium-duty pump

It might be made for medium-duties, but the compact millMAX-e pump maintains the high performance and reliability of standard millMAX heavy-duty pumps while reducing power consumption and the total cost of pumping for applications throughout the plant.

Optimise space utilisation. Reduced capital cost. Most efficient slurry pump in its class.

slurryMAX slurry pumps

You requested a split-case mining slurry pump with improved wear life and efficiency. The slurryMAX pump is our answer. These horizontal centrifugal slurry pumps are ideal for handling abrasive slurries in various mining and aggregate applications.

Even and predictable wear life. Interchangeable material options. Eliminate gland water requirements.

Frequently asked questions

FAQs for medium-duty pumps

What are medium-duty slurry pumps?

Medium-duty slurry pumps are designed to handle slurries with a moderate concentration of solids and abrasiveness. T hese pumps are suitable for various mining and industrial applications where the conditions are not as extreme as those handled by heavy-duty pumps.

When should you use a rubber vs metal vs urethane lined pump?

Choosing between lining options depends on the slurry characteristics and operating conditions. Rubber liners work well for fine particles. Metal liners are better against coarser slurries. Urethane is a stepping stone between rubber and metal, combining the characteristics of an elastomer with the tip speed limit of a high-chrome alloy.

What are the benefits of a recessed impeller?

Recessed impellers, such as that in our hMAX pumps, offer several benefits. The recessed profile allows clear passage of air-entrained slurries, without influencing the duty flow and head.Recessed impellers can also handle large particles and fibrous material without clogging and, because there is less direct contact with solids, impeller wear is reduced, extending operating life.
