Shanghai Semhai Pump Co., Ltd. stands at the forefront as a distinguished manufacturer and supplier of superior Sewage Pumps, Drainage Pumps, Submersible Pumps, and Sump Pumps within China. Our comprehensive lineup caters to all your waste water removal needs, offering an impressive array of water submersible pumps, sewage effluent sump pumps, and drainage pumps. We're proud to deliver top-quality solutions that ensure efficiency and reliability.
Our innovative wastewater solutions, including the Drainage Pump and Sewage Pump, are built upon a foundation of decades-long expertise. We guarantee unparalleled performance, unwavering reliability, cost efficiency, and exceptional serviceability, ensuring that our products meet and exceed industry standards.
The WQ series submersible sewage pump excels with its remarkable energy-saving features, anti-wrapping capabilities, non-blocking design, and self-installation and auto-control functions. It is unmatched in efficiently draining solid grains and long fiber debris, ensuring optimal performance.
Adopting a distinctive impeller structure and an innovative mechanical seal, this pump effectively transports liquids containing solids and long fibers. The pump's impeller, designed in a single or dual flow-path reminiscent of a smooth elbow, delivers exceptional flow-through performance. With an advanced turbine room design and dynamic-static balancing tests, the pump ensures stable and reliable operation. Its superior hydraulic performance, high efficiency, and versatile structures simplify pump station setups, reducing investment costs.
The impeller, a pivotal component of centrifugal pumps, acts as a force multiplier for liquids. As liquid enters the rotating impeller's center, it is harnessed by the vanes, gaining velocity and being discharged via centrifugal force. Within the casing, this kinetic energy is converted into head or pressure, dictating the pump's performance and efficiency. Impeller variations are tailored to specific applications, enhancing versatility.
For submersible sewage pumps, we offer a variety of impeller types to suit various needs: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each designed for optimal performance.
The robust copper electric motor paired with a UL water-proof armored cable guarantees a stable power supply for our submersible sewage pumps, accommodating large flow rates with ease.
The auto coupling set, also known as a guide rail set/system, allows for seamless pump maintenance. This slide rail assembly enables effortless lifting or lowering of the pump within sumps or chambers without disconnecting fittings or pipework. A typical kit comprises a base (duckfoot or pedestal), pump adaptor/guide hook, and upper rail positioning bracket, complete with lifting chains and shackles. Depending on the model, one or two rails guide the pump for precise seating or easy removal.
The guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
