This submersible pump is a multi-stage, speed-regulated device designed for raw water supply, groundwater lowering, and pressure boosting. It is constructed entirely of stainless steel DIN W.-Nr. EN 1.4301 and suitable for both horizontal and vertical installations. The pump has a built-in non-return valve and requires a three-phase synchronous high-efficiency permanent magnet motor with a frequency drive to operate efficiently. It is ideal for pumping clean, thin, non-aggressive liquids without solid particles or fibers in various applications such as water treatment fertigation, chemigation, dosing, controls & digital groundwater management, and drip irrigation systems.
