Shanghai Semhai Pump Co., Ltd. stands as a premier leader among manufacturers and suppliers in the realm of sewage, drainage, submersible, and sump pumps across China. We proudly present a comprehensive suite of solutions for wastewater removal, including an extensive array of water submersible pumps, sewage effluent sump pumps, and drainage pumps. Our offerings are meticulously designed to ensure peak performance and reliability, making us a trusted authority in the industry.
Our wastewater solutions, encompassing both drainage and sewage pumps, are the culmination of decades of unparalleled expertise. With an emphasis on exceptional performance, unwavering reliability, and superior cost efficiency, our products are engineered for optimal serviceability and enduring value.
The WQ series submersible sewage pump shines with a remarkable energy-saving effect and innovative features including wrapping-proof design, non-block capabilities, auto-installation, and auto-control. This pump excels in effectively draining solid grains and long fiber waste, offering an exceptional solution for heavy-duty sewage applications.
Leveraging a pioneering impeller structure and state-of-the-art mechanical seals, this pump efficiently transports liquids containing solids and long fibers. Its impeller, akin to a single or dual flow-path elbow, ensures exceptional flow-through performance. Enhanced by a well-engineered turbine room, the pump delivers superior hydraulic performance and high efficiency. Rigorous dynamic and static balancing tests guarantee stability and reliability, simplifying pump station setups and optimizing investment.
The impeller, a pivotal component of centrifugal pumps, transforms kinetic energy into pressure. As liquid enters the center and interacts with the rotating vanes, it is accelerated and discharged by centrifugal force. This dynamic process is crucial for pump efficiency, with varied impeller designs tailored for diverse applications ensuring optimal performance.
Our submersible sewage pumps offer versatile impeller options including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, catering to an array of operational needs and challenges.
The robust copper electric motor coupled with a UL water-proof armored cable provides a steadfast power supply, ensuring reliability and high flow rate performance for our submersible sewage pumps.
The auto coupling set, also known as a guide rail system, facilitates effortless pump maintenance. This slide rail assembly allows the pump to be smoothly lifted or lowered within a sump or chamber without detaching connections. Standard kits include a base, pump adaptor, guide hook, lifting chains, and shackles, ensuring efficient operation and secure seating.
Guide rail system come with the following attachment,
Fixing stand
Locking arrangement
Bend pipe
