SEMHAI stands as a premier manufacturer and supplier of high-performance Sewage Pumps, Drainage Pumps, Submersible, and Sump Pumps in China. We proudly offer a comprehensive array of solutions for wastewater removal. Our vast selection includes advanced water submersible pumps, efficient sewage effluent sump pumps, and reliable drainage pumps, making us your go-to source for all pumping needs in China.
Our wastewater solutions, including both Drainage and Sewage Pumps, are built upon decades of unparalleled expertise and innovation. They deliver exceptional performance, unmatched reliability, and cost-efficiency while ensuring ease of serviceability.
The WQ series submersible sewage pump is engineered for superior energy efficiency and offers innovative features such as wrapping-proof technology, non-blocking design, and automatic installation and control. It is particularly effective in draining solid particles and long-fiber waste material with ease.
Employing a groundbreaking impeller design and a novel mechanical seal, this pump efficiently handles liquids containing solids and long fibers. The impeller adopts a unique single or dual flow-path, akin to an elbow of the same cross-section, providing excellent flow performance. Coupled with a well-designed turbine room, it ensures stable and reliable operation. The impeller undergoes dynamic and static balancing tests, delivering advanced hydraulic performance, high efficiency, and versatile installation options, significantly reducing pump station complexity and investment costs.
Central to a centrifugal pump's functionality is the impeller, its rotating component. Liquid entering the impeller is accelerated by its vanes, gaining velocity and discharged through centrifugal force into the diffuser. This mechanism efficiently converts kinetic energy into pressure, greatly impacting pump performance and efficiency. Various impeller designs exist to meet diverse application needs.
For our submersible sewage pumps, we offer a range of impeller types: vortex, semi-open channel, non-clog closed, and non-clog with cutter options, providing solutions tailored to specific pumping requirements.
Equipped with a durable copper electric motor and UL-certified water-proof armored cable, our submersible sewage pumps ensure a stable power supply, handling large flow rates with ease.
Our auto-coupling set, also known as a guide rail system, streamlines pump maintenance. This slide rail assembly allows for simple lifting or lowering of pumps in sumps or chambers without disconnecting components. Each standard kit includes a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, upper rail bracket, lifting chains, and shackles. Depending on the model, the pump is guided by one or two (not included) rails to ensure proper seating or easy removal.
Our guide rail system includes the following attachments:
Fixing stand for secure installation.
Locking arrangement to ensure stability.
Bend pipe for efficient flow direction.
