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 can be installed horizontally or vertically. The pump includes a built-in non-return valve and requires a three-phase synchronous high-efficiency permanent magnet motor with a frequency drive to operate efficiently. Suitable for pumping clean, thin, non-aggressive liquids without solid particles or fibers, this pump supports applications in water treatment fertigation, chemigation & dosing, controls & digital groundwater management, and drip irrigation systems.
