SEMHAI proudly stands at the forefront as a distinguished manufacturer and supplier of Sewage Pumps, Drainage Pumps, Submersible Pumps, and Sump Pumps in China. We offer a comprehensive and versatile range of solutions for efficient waste water removal. Our extensive selection includes high-quality water submersible pumps, sewage effluent sump pumps, and drainage pumps, establishing our reputation as a leader in the industry.
Our waste water management solutions, including cutting-edge Drainage and Sewage Pumps, are built upon decades of industry expertise. They deliver unparalleled performance, reliability, cost efficiency, and ease of serviceability, embodying the pinnacle of innovation in waste water technology.
The WQ series submersible sewage pump is engineered with features that ensure remarkable energy efficiency, anti-wrapping protection, non-clogging design, automatic installation, and control. This pump is uniquely effective for draining solid particles and long fiber debris, making it an ideal solution for challenging sewage environments.
By utilizing a unique impeller structure alongside a modern mechanical seal, this pump excels in transporting liquids with solids and long fibers, outclassing traditional impeller designs. Its single or dual flow-path impeller offers exceptional flow-through performance, akin to a streamlined elbow section, while the thoughtfully designed turbine chamber ensures high-efficiency operation. Rigorous dynamic and static balancing tests on the impeller guarantee stable and reliable performance. The series boasts advanced hydraulic performance, diverse structural configurations, and flexible installation modes, simplifying pump station setups and reducing investment costs.
In a centrifugal pump, the impeller serves as the vital rotating component. Liquids enter the center of the spinning impeller, where they are captured by the vanes and accelerated to greater velocities before being expelled via centrifugal force into the diffuser case. This process largely converts kinetic energy into pressure or head. The efficiency and performance of a pump are primarily dependent on the impeller type, which can be customized to meet various application demands.
For our submersible sewage pumps, we offer a variety of impeller options: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, catering to diverse operational needs and challenges.
A robust copper electric motor and UL-certified waterproof armored cable provide a stable power supply for our submersible sewage pumps, ensuring reliable operation even under high flow conditions.
An auto coupling set, also known as a guide rail system, greatly enhances maintenance efficiency. This slide rail assembly allows easy pump lifting or lowering within a sump without disconnecting fittings or pipework, facilitating cleaning and maintenance. The standard kit includes components such as a base (duckfoot/pedestal), pump adaptor/guide hook, and upper rail positioning bracket, complete with lifting chains and shackles. Depending on the model, the pump is guided by one or two rails (not included) for proper seating or removal.
Guide rail system comes complete with the following attachments:
Fixing stand
Locking arrangement
Bend pipe
