Product Description

Shanghai Semhai Pump Co., Ltd., a prestigious leader in the realm of pump manufacturing, stands at the forefront as a premier supplier of Sewage Pumps, Drainage Pumps, Submersible Pumps, and Sump Pumps across China. Offering a comprehensive array of waste water management solutions, we take pride in presenting an extensive catalog of water submersible pumps, sewage effluent sump pumps, and superior drainage pumps.
Our cutting-edge waste water management solutions, encompassing Drainage Pumps and Sewage Pumps, are the epitome of decades of refined expertise, unmatched performance, unwavering reliability, cost-effectiveness, and seamless serviceability.

Product Description

The WQ series submersible sewage pump is engineered with advanced features such as exceptional energy-saving capabilities, an ingenious wrapping-proof design, non-blocking operation, automatic installation, and seamless auto-control. It excels especially in efficiently handling the drainage of solid grains and long fiber debris.

With an innovative impeller structure and cutting-edge mechanical seal, our pump ensures efficient transportation of liquids containing solids and long fibers. Unlike conventional impellers, it boasts a single or dual flow-path design, akin to an elbow of identical section offering superior flow-through performance. Complemented by a well-calibrated turbine room, the pump operates with outstanding efficiency, stability, and reliability, thanks to dynamic and static balancing tests on the impeller. Its advanced hydraulic performance, high efficiency, and versatile installation options simplify the pump station setup, thereby minimizing investment costs.

Detailed Photos

The impeller, a pivotal component of a centrifugal pump, orchestrates the movement of liquids. By channeling liquid into its core, the rotating impeller accelerates it, utilizing centrifugal force to discharge it into the casing. The casing's collection chamber expertly transforms Kinetic Energy into Head or Pressure. Impeller variations are meticulously designed to cater to a diverse array of applications, ensuring optimal pump performance and efficiency.

Our submersible sewage pumps offer a versatile selection of impellers: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller equipped with a cutter, catering to diverse operational needs.

The rugged copper electric motor, coupled with a UL-approved waterproof armored cable, guarantees a stable and consistent power supply essential for submersible sewage pumps managing large flow rates.

An auto coupling set or guide rail system is a transformative assembly that simplifies pump maintenance by allowing effortless lifting or lowering within a sump or chamber. This negates any need to disconnect fittings or pipework. Standard kits include a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, upper rail positioning bracket, and associated lifting chains and shackles. Depending on the model, the pump navigates one or two guiding rails, facilitating precise seating or swift removal from the system or sump.
Guide rail systems are accompanied by the following components:
Fixing stand
Locking arrangement
Bend pipe
