Pedestal sump pumps

Description pedestal sump pump:
As with immersible (cantilever) pumps the vertical motor is dry mounted and the pump hydraulics are submerged in the liquid. The pump and shaft is supported by bearings, making the pump sensitive for contaminated liquids. The bearings can be lubricated by external lubrication source. This however means that the pumped medium will be contaminated with the lubrication medium. 

Application:
In case of large negative suction heads or pumping volatile liquids, preventing cavitation.
