The RV-Series
Heavy Duty Submersible Slurry Pumps
Impeller Types
The RV Pumps are supplied in three basic models. Type 1, 2
& 3.
Type 1.
Semi-Open
impeller and pump casing with spray holes. Part of the
pressurized liquid is directed toward the bottom of the
sump. This not only agitates solids in the sump, but also
de-aerates the pump to prevent "air-blocking".
Type
2.
Closed
impeller and casing without spray holes for maximum
performance and high heads.
Type 3.
Vortex
impellers for non-clog pumping of fibrous material and
coarse solids. Can be equipped with or without spray holes.
