Drawing on 20 years’ experience with permanent magnet motors, Grundfos supplies the SPE pumping system with a permanent magnet (PM) submersible motor and tailored CUE variable speed drive.
A Grundfos PM motor ensures the highest possible energy efficiency and is made from high-grade, robust materials that increase the time between service. The SPE system builds on the proven reliability and longer lifetime of the SP Pump.
The permanent magnet motor provides close-to-zero rotor losses, resulting in the highest possible energy efficiency and 10% energy savings. With a lower operating temperature, the pump lifetime is prolonged significantly.
