Shanghai Semhai Pump Co., Ltd., a leader in manufacturing and supplying cutting-edge Sewage Pumps, Drainage Pumps, Submersible, and Sump Pumps across China, is at the forefront of wastewater management solutions. Our extensive range includes top-tier water submersible pumps, sewage effluent sump pumps, and versatile drainage pumps, catering to all your wastewater removal needs with unmatched efficiency.
Our Drainage Pumps and Sewage Pumps are the epitome of innovation, developed through decades of expertise to deliver unparalleled performance, reliability, and cost efficiency. They are designed for serviceability, ensuring long-lasting solutions for wastewater challenges.
The WQ series submersible sewage pump is a marvel of engineering, showcasing significant energy-saving features, anti-wrapping technology, and non-blocking capabilities. This pump is equipped with auto-installation and auto-control, providing an exceptional solution for the efficient drainage of solid grains and long fiber debris.
Featuring an advanced impeller design and a cutting-edge mechanical seal, this pump excels at transporting liquids laden with solids and long fibers. Unlike conventional impellers, our design offers superior flow-through performance with single or dual flow-paths akin to an elbow, housed in a meticulously engineered turbine chamber. This ensures optimal operation and stability, enhanced by dynamic and static balance testing, making it a paragon of hydraulic performance, efficiency, and easy station installation, leading to substantial investment savings.
The impeller is the centrifugal pump's powerhouse, expertly accelerating liquid from its center to higher velocities before discharging it via centrifugal force. Within the casing, much of this kinetic energy is converted into head or pressure. A pump's performance and efficiency hinge largely on its impeller design, with variations crafted to meet diverse application needs.
For submersible sewage pumps, we offer a variety of impeller types, including vortex, semi-open channel, non-clog closed, and non-clog impeller with cutter type, each tailored for specific operational requirements.
The robust copper electric motor and UL water-proof armored cable ensure that our submersible sewage pumps maintain a stable power supply, even at high flow rates, enhancing reliability and performance.
An auto coupling set, or guide rail system, is an ingenious assembly allowing a pump to be effortlessly elevated or lowered within a sump or chamber for maintenance without disconnecting fittings or pipework. A standard kit features a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, and upper rail positioning bracket, complete with lifting chains and shackles. Depending on model selection, the pump is guided by one or two rails (not included) to ensure precise seating and easy removal.
The guide rail system includes these essential attachments,
Fixing stand
Locking arrangement
Bend pipe
