The Sala series of horizontal ST pumps recessed and channel impeller

The ST-pump range consists of tough, general purpose slurry pumps particularly known for their induced flow impellers. The hydraulic design provides a very gentle handling of the slurry. The proven low attrition of pumped particles has made it the industrial standard for carbon transfer in gold leaching processes.
The ”cloggless” performance of the induced flow impellers also makes this product range ideal for all applications where large or long, stringy solids will be handled.



The STHM slurry pumps are also available with alternative impeller designs which allow optimum adaption to different media - from heavy suspensions to clean liquids.

Vortex or channel impeller
Vortex impeller for heavy suspension and liquid/gas mixture. Channel impeller for light suspensions and clean liquids.

V-belt drive
This permits alteration of the pump’s performance without opening the pump.

Bearing assembly
Cartridge type with grease lubricated roller bearings designed for more than 60 000 operating hours.

Shaft seal
Standard stuffing box with seal water. Optional mechanical seals.

Pumping parts
Standard pumping parts in cast iron, stainless steel, high chrome and some sizes in polyurethane or rubber lined. Other materials are available upon request.

Motor bed plate
Overhead motor bed plate gives compact installation with extra motor protection and simple belt tensioning.

Vortex impeller
The vortex impeller is recessed in the back of the pump casing, giving a free passage through the casing. The pump can normally pump anything that can pass through the connecting pipes.
