Shanghai Semhai Pump Co., Ltd. shines as a frontrunner in the manufacturing arena, supplying a comprehensive array of premium Sewage Pumps, Drainage Pumps, Submersible, and Sump Pumps across China. With pride, we present a robust lineup tailored for efficient wastewater removal, including top-tier water submersible pumps, sewage effluent sump pumps, and drainage pumps, all designed to meet the diverse needs of our clientele.
Our state-of-the-art wastewater solutions, such as the Drainage Pump and Sewage Pump, are crafted from years of refined expertise. These products boast remarkable performance, unwavering reliability, exceptional cost-efficiency, and unparalleled serviceability, embodying the pinnacle of innovation and craftsmanship in the industry.
The WQ series submersible sewage pump stands out with its impressive energy-saving capabilities, anti-wrapping features, and non-blocking design. Notably, it offers automatic installation and control while delivering exceptional results in draining solid grains and long fiber waste, setting a new benchmark in performance and efficiency.
This pump is engineered with a unique impeller structure and an innovative mechanical seal, enabling efficient transport of liquids containing solids and long fibers. The impeller, featuring a single or dual flow-path resembling an elbow of the same section, boasts superior flow-through performance. Its integration with a well-designed turbine room ensures high efficacy. Having undergone dynamic and static balancing tests, the pump guarantees stable and reliable operation, offering advanced hydraulic performance and high efficiency. With multiple structural and installation options, it simplifies pump stations and maximizes investment returns.
Within a centrifugal pump, the impeller is the key rotating component. Liquids enter the center of the rotating impeller, where the impeller's vanes increase the liquid's velocity, subsequently discharging it by centrifugal force into the casing. This casing's collection chamber transforms much of the kinetic energy into head or pressure, impacting overall pump performance and efficiency. Various impeller modifications cater to a range of applications, optimizing efficiency and adaptability.
For submersible sewage pumps, we offer an array of impeller types, including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, all designed to suit diverse operational needs.
Our pumps are equipped with a powerful copper electric motor and a UL waterproof armored cable, ensuring a stable and robust power supply for submersible sewage pumps handling high flow rates with reliability and efficiency.
The auto coupling set, also known as a guide rail set/system, is a sophisticated slide rail assembly. It allows easy lifting or lowering of the pump within a sump or chamber for maintenance without disconnecting fittings or pipes. The standard kit includes a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, upper rail positioning bracket, lifting chains, and shackles. Depending on the selected model, the pump is guided by one or two rails (not included), ensuring proper seating with a positive seal or facilitating easy removal from the system/sump.
Guide rail system includes the following attachments:
Fixing stand with durable support mechanisms.
Locking arrangement designed for secure and firm positioning.
Bend pipe for seamless flow direction and reduced turbulence.
