Shanghai Semhai Pump Co., Ltd. is a prestigious leader in the manufacturing and supply of high-quality Sewage Pumps, Drainage Pumps, Submersible Pumps, and Sump Pumps throughout China. Our comprehensive range of solutions for wastewater removal includes an unparalleled selection of water submersible pumps, sewage effluent sump pumps, and drainage pumps, setting the standard for excellence in the industry.
Our innovative wastewater management solutions, such as the Drainage Pump and Sewage Pump, are the culmination of decades of expertise. These pumps are renowned for their outstanding performance, rock-solid reliability, cost-effectiveness, and superior serviceability, making them an indispensable choice for efficient waste disposal.
The WQ series submersible sewage pump is engineered with key features such as remarkable energy-saving capabilities, anti-wrapping technology, non-blocking design, automatic installation, and self-control. Its unique ability to handle the drainage of solid grains and long-fiber waste makes it an exceptional choice for modern waste management.
With its innovative impeller structure and state-of-the-art mechanical seal, this pump excels at transporting liquids containing solids and long fibers. Unlike traditional designs, its impeller features a single or dual flow-path, reminiscent of an elbow of similar section, offering exceptional flow-through performance. Coupled with a well-designed turbine chamber, this pump operates with impressive efficiency. Dynamic and static balancing tests ensure the impeller runs smoothly and reliably. This series offers advanced hydraulic performance, high efficiency, and diverse structures and installation modes, significantly simplifying pump stations and reducing investment costs.
In a centrifugal pump, the impeller is the heart of the operation. As liquid enters the center of this rotating component, the impeller's expertly designed vanes accelerate the liquid to a higher velocity, discharging it via centrifugal force into the casing (diffuser). The collection chamber within the casing converts the kinetic energy from velocity into head or pressure, playing a crucial role in pump performance and efficiency. Diverse impeller variations are tailored to meet a variety of applications.
Our submersible sewage pumps are equipped with a versatile range of impeller options including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with a cutter, providing customizable solutions for diverse needs.
Featuring a robust copper electric motor and UL waterproof armored cable, our submersible sewage pumps deliver stable power supply and support high flow rates, embodying durability and reliability for demanding applications.
The auto coupling set, also known as a guide rail system, revolutionizes maintenance efficiency. This slide rail assembly allows for easy lifting or lowering of the pump within a sump or chamber for cleaning or maintenance without disconnecting any fittings, fixings, or pipework. A standard kit comprises a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, and upper rail positioning bracket. These sets include lifting chains and shackles, guiding the pump with one or two rails (not included) to ensure secure seating and seamless removal from the system.
The guide rail system is equipped with the following attachments,
Fixing stand, ensuring stability and secure placement.
Locking arrangement, providing enhanced security and reliability.
Bend pipe, facilitating smooth directional flow.
