Dayliff DS 30 submersible pumps are high-performance multistage centrifugal impeller pumps specifically designed for borehole applications.
Dayliff DS 30 Pump Construction
The pump is made up of stainless steel parts and water-lubricated rubber bearings.
A submersible motor is fitted beneath the pump, and suction is through a strainer between the pump and motor.
MOTOR
The pump is connected to a 2-pole asynchronous sealed liquid-cooled motor made of stainless steel. The motor requires a remote starter, and in case of an inconsistent power supply, an additional quick tripling control relay is recommended.
A DOL starter is recommended due to low starting torques of submersible motors.
