Slurry pumps

All Metso Slurry Pumps are designed specifically for abrasive slurries and feature a robust design with ease of maintenance.
Developed from the old SALA sump pump, VASA G model, the Metso type VS vertical sump is the next generation heavy duty sump pump.

Simple installation

With small slurry pumps is it possible to hang the pump in the slurry by the lifting bracket provided. Larger units are normally bolted to
a permanent base plate. Pump bearings are located in a housing above the base plate for accessibility and protection. All pumps can
run dry intermittently. Pumps with metal pump parts can run dry for an unlimited length of time. Special designs giving extended length, with the bearings below the base plate, are available on request.

Cantilever design

The heavy duty pump shaft is of cantilever design, hanging below the bearing housing. There are no submerged bearings, stuffing box or shaft seals. This design ensures minimum maintenance and eliminates the need for water flushing. The pump shaft is mounted in grease lubricated roller bearings.
Impeller clearance is maintained by external axial adjustment of the shaft/bearing assembly. Bearings have double seal protection against contamination.

Impeller

Type O – The semi-open impeller provides better solids handling than the closed impeller design and is less sensitive to air blocking on intermittent operation.

Type W – Vortex induced flow impeller for clogless pumping of long fibrous or coarse solids. It can be fitted into a casing with or without spray holes. Large clearance between casing and impeller – well suited for pumping fibrous slurries (paper stock, wood chips, municipal sludge, etc.), aerated or frothy liquids (vortex impeller will not be air blocked) and any application where the pump is required to pass the occasional large solids.

Type WFR – We have developed a fully recessed induced vortex impeller for the VSHM pumps. This is specifically designed for carbon transfer in gold leaching processes because it provides the lowest possible attrition of the pumped active carbon particles.

Type C – Closed impeller for higher heads and efficiencies. Can not be combined with type S, casings with spray holes.

Type A – Semi-open impeller and robust extended shaft with a slurry agitator. This design is best suited for coarse rapid settling solids and dredging type applications.

Type S – Pump casing with spray holes. The spray holes direct some of the slurry towards the sump bottom, thereby agitating settled solids. Available from VS50 to VS200.
