D3SP1 pumps are compact 3” diameter submersible multistage centrifugal pumps specifically designed for small scale water supplies from boreholes and wells. Material of construction is engineering plastic impellers and diffusers, brass inlet and outlet chambers and stainless steel pump sleeve. All pumps are provided with 20m cable and a control unit.
MOTOR The pump is coupled to a two pole sealed motor with copper windings and constructed principally from stainless steel. A separate control unit is included which incorporates an isolator, run indicator light, thermal overload protection and start capacitor which can be connected directly to mains power. Additional protection by a Dayliff AVS or similar power protection controller is recommended.
