4" QGD submersible screw pump is a top-grade product based on the advanced technique from America and Italy, using stainless steel for casing, and shaft, With wider viscosity range of delivering medium, QGD series pump is less sensitive to liquid impurities . With elegant appearance, this series has effecient motor, large flow and high head, which obviously reduces borehole cost, extends service life, and saves power. It is widely used in mining industry, agriculture, aquaculture, and family water supply.
