A Decade of Engineering Reliable Sewage Pumps
Since 2014, Shanghai Haquan Pump Valve Manufacturing Co., Ltd. has grown from a specialist pump workshop into a professional sewage pump manufacturer and authorized dealer of genuine Wilden pumps, serving demanding industries worldwide.
Built on Hydraulics, Driven by Reliability
Shanghai Haquan Pump Valve Manufacturing Co., Ltd. was founded in 2014 in Fengxian District, Shanghai, as a professional sewage pump manufacturer — built on the conviction that buyers deserve pumps engineered for their exact application, not generic units that fail early in the field.
Today we design, manufacture and export a full sewage-focused range — stainless-steel sewage pumps, ZW and ZWL self-priming pumps, YW submersible sewage pumps, the QBY air-operated diaphragm series, GNWQ and WQK cutter submersible pumps, IHG/IHW/IRG/IRW pipeline pumps, metering pumps, high-head sewage pumps, and QDX and QD submersible pumps. As an authorized dealer, we also supply genuine Wilden AODD diaphragm pumps and spare parts — all shipped to customers worldwide.
From municipal septic-tank treatment and food & beverage plants to farmland irrigation, biopharmaceutical and petrochemical sites, Haquan pumps keep critical processes flowing. Our growth has been earned one duty point at a time: precise hydraulic selection, robust materials, rigorous testing and after-sales support international buyers can rely on.

Our Vision
