SEMHAI proudly stands as a premier manufacturer and supplier of top-notch Sewage Pumps, Drainage Pumps, Submersible, and Sump Pumps in China. We offer an unparalleled array of solutions for waste water removal, including our extensive selection of water submersible pumps, sewage effluent sump pumps, and drainage pumps. Our commitment to quality and innovation has solidified our reputation as leaders in the industry.
Our wastewater solutions, including our Drainage and Sewage Pumps, are the culmination of decades of expertise. They are engineered for superior performance, unwavering reliability, outstanding cost efficiency, and remarkable serviceability, making them a top choice for discerning customers.
The WQ series submersible sewage pump is a marvel of engineering with its exceptional energy-saving capabilities, anti-wrapping design, non-blocking technology, auto-installation, and auto-control features. It excels in draining solid particles and long fiber debris effortlessly.
Featuring a unique impeller structure and an innovative mechanical seal, this pump is adept at transporting liquids containing solids and long fibers. Unlike conventional impellers, it employs a single or dual flow-path design, mimicking an elbow for superior flow-through performance. Paired with a well-designed turbine chamber, it ensures effective operation. Rigorous dynamic and static balancing tests on the impeller guarantee stable and reliable performance. This series boasts advanced hydraulic performance, high efficiency, various structures, and installation modes, streamlining the pump station and reducing investment costs.
At the heart of a centrifugal pump lies the impeller, a dynamic component that accelerates liquid introduced at its center, discharging it through centrifugal force into the diffuser casing. This casing ingeniously converts kinetic energy into pressure, influencing pump performance and efficiency. Impellers come in various designs tailored to specific applications, ensuring optimal function.
For submersible sewage pumps, we provide a selection of impeller options, including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each designed to meet diverse operational needs.
Our robust copper electric motor, coupled with a UL water-proof armored cable, ensures a consistent and stable power supply for submersible sewage pumps handling significant flow rates.
Our auto coupling set, also known as a guide rail set/system, facilitates easy pump maintenance. This slide rail assembly allows for seamless lifting or lowering of the pump within a sump or chamber for cleaning or upkeep without disconnecting fittings or pipework. The standard kit includes a base ("duckfoot" or "pedestal"), pump adaptor/guide hook, and upper rail positioning bracket, complete with lifting chains and shackles. Depending on the selected model, the pump can be guided by one or two rails, ensuring proper seating or easy removal.
The guide rail system is equipped with the following attachments,
Fixing stand
Locking arrangement
Bend pipe
