Product Description

Shanghai Semhai Pump Co., Ltd. proudly stands at the forefront as a leading manufacturer and supplier of Sewage Pumps, Drainage Pumps, Submersible, and Sump Pumps in China. We offer a comprehensive range of high-performance pumps designed for efficient wastewater removal. Our extensive selection includes water submersible pumps, sewage effluent sump pumps, and drainage pumps, meeting the diverse needs of our clients in China.
Our sophisticated wastewater solutions, featuring the Drainage Pump and Sewage Pump, are built upon decades of experience, ensuring superior performance, unmatched reliability, cost efficiency, and easy serviceability.

Product Description

The WQ series of submersible sewage pumps are engineered with standout features such as remarkable energy-saving capabilities, anti-wrapping technology, non-blocking design, auto-installation, and auto-control. These pumps excel at efficiently draining solid grains and long fiber waste, ensuring smooth operation in challenging environments.

With a unique impeller structure and innovative mechanical seal, this pump effectively transports liquids containing solids and long fibers. Its impeller adopts a single or dual flow-path design, akin to an elbow of the same section, offering exceptional flow-through performance. Coupled with a well-designed turbine room, the pump operates efficiently and reliably. Comprehensive dynamic and static balancing tests ensure stable and trustworthy performance. This series boasts advanced hydraulic performance and high efficiency, with diverse structures and installation modes, optimizing pump station operations and reducing investment costs.

Detailed Photos

The impeller, the rotating heart of a centrifugal pump, propels liquid from the center to the periphery, boosted to higher velocity by its vanes. This kinetic energy is transformed into head or pressure as the liquid exits the casing's diffuser. The impeller's design is crucial to pump performance and efficiency, with various configurations available to suit different applications.

For submersible sewage pumps, we offer a selection of impeller types: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each tailored to specific operation needs.

Our robust copper electric motor, paired with UL water-proof armored cable, ensures a stable power supply, supporting the high flow rate demands of our submersible sewage pumps.

The auto-coupling set, also known as a guide rail set/system, is a slide rail assembly that allows for seamless lifting or lowering of the pump within a sump or chamber, facilitating cleaning or maintenance without disconnecting fittings. A standard kit includes a base (duckfoot or pedestal), pump adaptor/guide hook, upper rail positioning bracket, and lifting chains with shackles. Depending on the model, the pump is guided by one or two rails (not included) to its proper seating with a positive seal or for easy removal.
Guide rail system comes with the following attachments:
Fixing stand
Locking arrangement
Bend pipe
