4" QJ series deep well pump is a top-grade product based on the advanced technique from America and Italy, using stainless steel for casing, shaft, spline, copper for outlet and inlet, high-strength and abrasion-resistant modified composite PC material for impeller and diffuser, adopting brand-new "Folding impeller" structure. 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.
