The GNWQ(D) Series grinder pumps are widely applied in industry, agriculture, mining, construction, municipal, environmental protection, etc. They are suitable for draining water containing particles such as shot fibers, paper scraps, etc. and soft solid, such as muddy water, dirty water, domestic wastewater, sewage, manure, etc. With a good capacity of anti-clogging and anti-winding, the grinder pumps are especially applicable for pumping household wastewater and mixed fluid with insoluble solids content such as fibers, bags, belts, straw, cloth, paper, sand, etc. They are ideal equipment for agricultural irrigation and drainage, pool silt cleaning and construction sites, but not apply to the location with explosion-proof requirements.
