DAYLIFF DS submersible pumps are designed specifically for borehole supply applications. They are of multistage centrifugal impeller design and all parts are made from stainless steel with water lubricated rubber bearings. A submersible motor is fitted beneath the pump and suction is effected through a strainer between the pump and motor.
 

MOTOR
The pump is coupled to a sealed liquid cooled oil filled 2-pole asynchronous squirrel-cage motor constructed of stainless steel. Single phase motors are supplied complete with purpose designed control boxes, while three phase motors require a remote starter. A DAYLIFF Electronic Pump Controller is recommended for comprehensive pump control including wireless low level, motor overload and irregular power supply protection.
