Shanghai Semhai Pump Co., Ltd. is at the forefront of innovation as a distinguished manufacturer and supplier of Sewage Pumps, Drainage Pumps, Submersible Pumps, and Sump Pumps in China. We proudly present a comprehensive range of solutions designed for efficient waste water removal. Our extensive selection includes high-performing sewage, sump, submersible, and drainage pumps, all crafted to meet the stringent demands of the industry.
Our state-of-the-art wastewater solutions, including the versatile Drainage Pump and robust Sewage Pump, are the culmination of decades of expertise. They exemplify unmatched performance, unwavering reliability, cost efficiency, and exceptional serviceability.
The WQ series submersible sewage pump is engineered for excellence with features such as significant energy-saving benefits, anti-wrapping, non-blocking capabilities, auto-installation, and auto-control. It is uniquely effective in managing solid grains and long-fiber waste drainage with precision.
Our unique impeller structure, coupled with a revolutionary new-style mechanical seal, enables efficient transport of liquids containing solids and long fibers. Unlike conventional designs, our impeller boasts a single or dual flow-path, akin to an elbow with superior flow-through performance. With a dynamic and static balancing test, it ensures stable and reliable operation. The advanced hydraulic performance and high efficiency, along with versatile structures and installation modes, simplify the pump station construction while optimizing investment.
The impeller, as the centrifugal pump's driving force, captures liquid directed into its center, accelerating it for discharge through centrifugal force. The casing's collection chamber ingeniously converts kinetic energy into pressure, making impeller type critical to pump performance and efficiency. Various impeller designs are tailored to diverse applications.
For our submersible sewage pumps, we offer a range of impeller options: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each engineered to meet specific operational needs.
The submersible sewage pump is powered by a robust copper electric motor and protected with UL water-proof armored cable, ensuring a stable power supply even under demanding conditions.
The auto coupling set, known as a guide rail set/system, is a versatile slide rail assembly that facilitates effortless pump lifting or lowering for cleaning or maintenance. This system eliminates the need to disconnect pipe work and fittings, featuring a standard kit with a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, upper rail bracket, lifting chains, and shackles. Depending on the model, the pump is guided by one or two rails, ensuring precise seating or easy removal.
The guide rail system comes equipped with the following attachments:
Fixing stand
Locking arrangement
Bend pipe
