We are dedicated to delivering a comprehensive range of wastewater removal solutions with our extensive array of high-quality water submersible pumps, efficient sewage effluent sump pumps, and versatile drainage pumps.
Our cutting-edge wastewater solutions, including our renowned Drainage and Sewage Pumps, are the culmination of decades of expertise. They are crafted for ultimate performance, unwavering reliability, and optimized cost efficiency, ensuring exceptional serviceability.
Experience the WQ series submersible sewage pump, a marvel of engineering with outstanding energy-saving capabilities, anti-wrapping technology, and a non-block design. This pump is engineered for easy auto-installation and control, excelling at removing solid particles and long-fiber debris with unmatched proficiency.
Featuring a groundbreaking impeller design and an innovative mechanical seal, this pump is tailored to transport liquids laden with solids and long fibers. Its impeller, crafted with a single or dual flow-path similar to an efficient elbow, is designed for superior flow-through performance and stability. The high-performance turbine room enhances its efficacy, while dynamic and static balancing tests ensure stable, reliable operation. This series promises advanced hydraulic performance, high efficiency, and versatile installation options, thereby streamlining pump station setups and optimizing investment.
The impeller, the heart of a centrifugal pump, is key to its operation. As liquid enters the center of this rotating marvel, it is accelerated by the vanes, gaining velocity and discharged through centrifugal force into the diffuser. This process transforms kinetic energy into pressure. The type of impeller used greatly influences pump performance and efficiency, with various designs tailored for specific applications.
Our submersible sewage pumps offer a selection of impellers: the vortex type, semi-open channel type, non-clog closed type, and the non-clog impeller with a cutter, providing flexibility to meet diverse needs.
Equipped with a robust copper electric motor and UL-certified waterproof armored cable, our submersible sewage pumps deliver a stable and powerful flow rate, ensuring dependable operation.
The auto coupling set, or guide rail system, revolutionizes maintenance by allowing effortless pump lifting or lowering within a sump. This rail assembly eliminates the hassle of disconnecting fittings, featuring components like a base pedestal, pump adaptor, lifting chains, and shackles. Choose from models with one or two guiding rails, which secure the pump's seating or facilitate its removal with ease.
Guide rail system comes with the following attachment,
Fixing stand
Locking arrangement
Bend pipe
