4SR6



Pedrollo 4SR6 submersible pumps are specifically designed for domestic and small scale water supply from boreholes, though can also be used in other submersible applications in either vertical or horizontal configuration. They feature a hydraulic design that incorporates floating impellers which together with especially resistant component materials provide high resistance to sand content in the pumped water.

The pump impellers and diffusers are made from engineering plastic while the stage casings, top housing, suction connector, pump sleeve and shaft are made of AISI 304 stainless steel. The pump is supplied with a 1.5m tail cable.

MOTOR
Pumps are coupled to a  two pole sealed motor constructed principally from stainless steel. A  separate control box is also included for single phase pumps which incorporates a fused rotary switch, run indicator light, thermal overload with manual reset and capacitor which can be connected directly to the mains power supply. 3 phase motors require a remote starter and if irregular electrical supply is prevalent an additional quick tripping voltage sensing relay is recommended.
