GRUNDFOS SPE submersible pumps are designed specifically for heavy duty 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. Standard pumps are designed for the pumping of non-aggressive water. 'N and R' versions are available for applications requiring a higher degree of corrosion resistance. All SPE pumps carry a drinking water approval and meet European Minimum Efficiency Index guidelines

The pump is coupled to a premium efficiency permanent magnet motor giving significant savings up to 10% in energy consumption type allowing for higher running temperatures. It also enables a full synchronous 3000rpm speed which provides for improved pump performance

The SPE pump fitted with the GRUNDFOS CUE control unit which acts as both the starter and provides protection against dry running, mechanical motor defects, excessive motor running temperature and irregular power supply. The CUE is a variable speed drive that ensures low starting torques and also allows for variation of pump performance. SPE is available with 6” motors upto 45 kW.  For cable lengths below 300M sine wave filter is not required for SPE with CUE.
