GP series is a high-efficiency grinder pump with premium efficient IE3 motor. Designed for sewage applications requiring high delivery heads and low flow rates, the GP series operates effectively even with small pipe diameters.
Its advanced grinding system - featuring a rotary knife and stationary cutting ring - shreds solids into fine particles, enabling smooth and clog-free pumping. The hydraulics are constructed with a durable multi-channel open impeller, and the special conformation of the hydraulic part ensures the efficient expulsion of solids while preventing impeller fouling. Suitable application for example; Soiled liquids containing fibres and filaments, Professional and heavy-duty applications, etc...
