SEMHAI stands proudly as a distinguished leader in the manufacturing and supply of top-tier Sewage Pumps, Drainage Pumps, Submersible Pumps, and Sump Pumps throughout China. We offer a comprehensive collection of pumps designed specifically for efficient wastewater removal. Our expansive selection includes high-quality water submersible pumps, sewage effluent sump pumps, and drainage pumps, establishing us as a trusted provider in China.
Our innovative wastewater solutions, including the Drainage Pump and Sewage Pump, are built upon decades of expertise. These solutions offer unmatched performance, reliability, cost efficiency, and ease of service, ensuring that you receive only the best for your wastewater management needs.
The WQ series submersible sewage pump is engineered with features that include remarkable energy-saving capabilities, anti-wrapping properties, non-blocking design, auto-installation, and auto-control. It is uniquely effective in draining solid particles and long fiber debris, making it an ideal choice for demanding environments.
Featuring a pioneering impeller structure and a modern mechanical seal, this pump effortlessly transports liquids containing solids and long fibers. Unlike conventional designs, the impeller utilizes a single or dual flow-path, akin to an elbow of the same section, offering superb flow-through performance. Paired with a well-designed turbine room, this pump operates with exceptional efficiency. The dynamic and static balancing tests ensure that it runs steadily and reliably. Its advanced hydraulic performance, coupled with diverse structures and installation modes, simplifies pump station design and reduces investment costs.
In a centrifugal pump, the impeller is the crucial rotating component. Liquids entering the center are captured by the vanes, accelerating to higher speeds before being discharged by centrifugal force into the diffuser case. The casing's collection chamber converts kinetic energy into head or pressure, largely influencing pump performance and efficiency. Various impeller designs have been crafted to meet a range of application needs.
For our submersible sewage pumps, we offer a selection of impeller types: vortex, semi-open channel, non-clog closed, and non-clog with cutter. Each is designed to suit specific operational needs.
Our submersible sewage pumps come equipped with a robust copper electric motor and UL-certified waterproof armored cable, guaranteeing stable power delivery for handling high flow rates.
An auto coupling set, also known as a guide rail system, is engineered for simple pump maintenance. This slide rail assembly allows easy lifting or lowering of a pump within a sump or chamber for cleaning or maintenance without disconnecting fittings or pipework. A typical kit includes a duckfoot or pedestal base, a pump adaptor/guide hook, and an upper rail positioning bracket, complete with lifting chains and shackles. Depending on the chosen model, the pump is guided by one or two rails, ensuring correct seating with a positive seal or straightforward removal.
Guide rail systems include the following attachments:
Fixing stand
Locking arrangement
Bend pipe
