Shanghai Semhai Pump Co., Ltd. is a frontrunner in the manufacturing and supply of top-tier Sewage Pumps, Drainage Pumps, Submersible Pumps, and Sump Pumps throughout China. Our comprehensive range of products is designed for effective wastewater removal, encapsulating excellence in water submersible pumps, sewage effluent sump pumps, and drainage solutions, all crafted to meet the highest standards of quality and performance.
Our expertly engineered wastewater solutions, including the Drainage Pump and Sewage Pump, are rooted in decades of industry expertise, offering unparalleled performance, reliability, and cost efficiency, alongside superior serviceability. These solutions embody our commitment to innovation and excellence.
The WQ series submersible sewage pump is a marvel of engineering, boasting features such as significant energy-saving effects, anti-wrapping capabilities, non-blocking design, convenient auto-installation, and auto-control. Its unique proficiency in managing solid grains and long fiber waste ensures optimal drainage and performance.
This pump series features a revolutionary impeller structure and innovative mechanical seal, expertly handling liquids containing solids and long fibers. The impeller's single or dual flow-path design, akin to a well-engineered elbow section, ensures exceptional flow-through performance. Enhanced by a well-designed turbine room and rigorous dynamic and static balancing tests, these pumps deliver stable, reliable, and highly efficient operation, offering advanced hydraulic performance and versatile installation options that streamline pump station design and reduce investment costs.
The impeller, the heart of a centrifugal pump, is pivotal to effective performance. As liquid enters the center of the rotating impeller, it is swiftly captured by the vanes, accelerated to increased velocity, and then discharged by centrifugal force into the casing. The kinetic energy is transformed into head or pressure within the collection chamber, dictating the pump's performance and efficiency. Our impeller designs are meticulously crafted to suit a wide range of applications, ensuring unparalleled adaptability.
Our submersible sewage pumps feature a variety of impeller options, including vortex type, semi-open channel type, non-clog closed type, and innovative non-clog impeller with cutter type, each tailored to meet specific operational needs.
Equipped with a robust copper electric motor and UL-rated waterproof armored cable, our submersible sewage pumps guarantee a consistent and stable power supply, perfectly suited for handling substantial flow rates with ease and reliability.
The auto coupling set, also known as a guide rail system, offers seamless pump maintenance. This slide rail assembly facilitates effortless lifting or lowering of the pump within a sump or chamber for cleaning or servicing, eliminating the need for disconnection of fittings or pipework. Each kit, comprising a base ("duckfoot" or "pedestal"), pump adaptor/guide hook, and upper rail positioning bracket, is complete with lifting chains and shackles. Depending on the model, the pump is guided by one or two rails, not included, to ensure precise seating and simple removal.
Our guide rail system includes the following components:
Fixing stand
Locking arrangement
Bend pipe
