Dayliff DS 5 multistage centrifugal impeller pumps are designed specifically for borehole supply applications.
Dayliff DS 5 Pump Construction
These pumps are built from stainless steel parts and include rubber bearings. A submersible motor is close-coupled to the pump with a strainer in between that allows suction to occur.
The pump is coupled to a sealed, liquid-cooled 2-pole asynchronous motor designed from stainless steel.
Dayliff DS 5 Motor Features
The pump is coupled to a sealed liquid-cooled 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.
