The SPE 300S250-4 is a multi-stage, speed-regulated submersible pump used for raw water supply, groundwater lowering, and pressure boosting. It is strictly for pumping clean, thin, non-aggressive liquids that are free of solid particles or fibers. The pump itself is constructed entirely from Stainless steel (DIN W.-Nr. EN 1.4301). It can be installed horizontally or vertically and comes equipped with a built-in non-return valve. It is driven by a 3-phase synchronous high-efficiency permanent magnet submersible motor (canned type). The motor's liquid-contacting surfaces are stainless steel. As an IPM (Interior Permanent Magnet) motor, it has embedded magnets and requires a frequency drive for both starting and regulating its speed.
