The SPE 475S400-3 is a multi-stage, speed-regulated submersible pump engineered for raw water supply, groundwater lowering, and pressure boosting. It is designed to pump clean, thin, non-aggressive liquids that are free of solid particles or fibers. The pump is constructed entirely from Stainless steel (DIN W.-Nr. EN 1.4301) and features a built-in non-return valve. It can be installed both horizontally and vertically. The motor is a 3-phase, high-efficiency synchronous permanent magnet submersible motor of the canned type. All motor surfaces in contact with the media are made of stainless steel. This IPM (Internal Permanent Magnet) motor, with embedded magnets in its metal-clad rotor, requires a frequency drive for starting and speed regulation.
