BATESCREW 

Volute type Sludge Pumps


This type of single-vane centrifugal pump operates with an unbalanced impeller and consequently at lower speed than a vortex pump, it is, however, more mechanically efficient and capable of pumping to higher heads than a vortex pump.
It is well suited to pumping thick slurries and long-stranding contaminants such as grasses, string, rope etcetera, as may be found in sewerage applications.

Inlets are of smaller diameter than outlets, so that solids entering will find adequate passage through the pump.
