Hard metal impellers and elastomer molded/ hard metal liners are used to handle corrosive/abrasive froth slurries.
he enlarged inlet of throat bush reduces NPSHr(only for WXF(R)/WLF(R)).
The blade shape of open impeller and venting pipe in suction pipe help to get as more as froth or viscous slurries into the pump, minimize the pump size and increase efficiency.
Venting pipe helps to relief air from system, promotes the movement of the froth slurry into the impeller eye.
Gland seal, gland seal with venting system, and Mechanical seal.
(When froth factor is over 1.8, we adopt gland seal with venting system to help release air from the pump.)
