HS series

Our submersible solids handling HS pumps have steep curves and can handle solids up to 60%.

The HS is a hard wearing and versatile submersible solids handling pump featuring steep curves, advanced double mechanical seal design, high Chrome wet end parts, H-class windings; capable of handling Class 1, 2 and some Class 3 slurries and capacities up to 3000 US GPM.


A robust mechanical seal is an essential part of any successful slurry pumping formula which is why when we designed the HS pump we made sure we engineered the perfect seal to accompany it.

HS Series seals are individually protected and in tandem configuration. This means each set of springs are protected from the slurry and provides equal and real back up in the event a lower seal is compromised.

Next, we made some industry leading advancements in the seal chamber itself. We incorporated anti-vortex oil veins, which ensure the seal remains clean and lubricated without the internal eddies and vortexes created by oil lifters. Then, we boosted the pressure venting in the seal chamber to allow for greater submergence as well as less internal pressure on the seal itself.

All this means you get the best bang for your buck while having the peace of mind that we invested our time in all the right places.

The HS-E Wet End has a fully recessed vortex impeller that permits an unobstructed passage.

This design allows solids with the same diameter of the discharge to pass through without the danger of clogging. It has some of the highest efficiencies available for a recessed impeller due to the unique axial spiral casing.

The E Wet End has a fully recessed vortex impeller that permits an unobstructed passage of large solids. Fibrous material can also be handled without difficulty due to the natural flow of the fluid through the pump casing and the fact that the flow is virtually isolated from the impeller (only 15% of pumped liquid is in contact with the impeller). This pump is ideally suited for low shear applications.

The HS-S Wet End is a fantastic medium duty, high efficiency solids handling pump for Class 1, Class 2 and some Class 3 slurries.

This semi-open wet end boasts a special elliptical cut-water design to improve efficiency and reduce wear. It also has curved back vanes to help displace solids from behind the impeller and an adjustable front wear plate.

The S Wet End is a fantastic semi-open, high efficiency, solids handling pump. This wet end is capable of handling Class 1, 2, & some Class 3
slurries. It boasts a special elliptical cut-water design which maximizes efficiencies and reduces wear.
