Pedrollo 4SR1/39 Submersible Borehole Pump 4 Inch

Built for four inch boreholes, the Pedrollo 4SR1/39 is a multistage submersible pump in which a stack of stages raises water from depth up to surface storage. The pump end couples to a submersible motor and the assembly is lowered into the hole on the rising main.

Low yield boreholes and domestic or smallholding supplies suit a unit of this size, where a modest flow is drawn steadily against a high head. Installation needs correctly rated submersible cable, control gear and protection against dry running should the standing water level fall.
