Our revolutionary wastewater solutions, encompassing our state-of-the-art drainage and sewage pumps, are the embodiment of decades-long expertise. Boasting unmatched performance, unwavering reliability, superior cost efficiency, and unparalleled serviceability, these solutions redefine industry standards and set a new benchmark in water management.
Introducing the WQ series submersible sewage pump, a marvel of engineering with groundbreaking features like substantial energy savings, anti-wrapping, non-blocking capabilities, and autonomous installation and control. This pump offers exceptional performance in draining solid grains and long fiber refuse, positioning it as an indispensable asset in waste management.
Harnessing a revolutionary impeller design and innovative mechanical sealing, the WQ series excels in conveying liquids infused with solids and long fibers. Unlike traditional impellers, our design incorporates either single or dual flow-path configurations, akin to a finely-crafted elbow, delivering exceptional flow-through performance. With a precision-engineered turbine room and subjected to rigorous dynamic and static balancing tests, this pump ensures stable and reliable operation. Its advanced hydraulic performance, high efficiency, and multiple structural configurations offer versatile installation options, streamlining pump station design and reducing investment costs.
The impeller, a pivotal component of centrifugal pumps, masterfully channels liquid into the core of its spinning structure. As it is propelled by the vanes, the liquid gains velocity and is thrust outward by centrifugal forces, ultimately transforming kinetic energy into pressure. The incredible performance and efficiency of a pump are intrinsically tied to the impeller design, with various models crafted to suit a wide array of applications.
Our submersible sewage pumps come equipped with a versatile selection of impellers: vortex type, semi-open channel type, non-clog closed type, and the innovative non-clog impeller with cutter type, each tailored for specific operational needs.
The robust copper electric motor, paired with UL-certified, water-proof armored cable, ensures a consistent and stable power supply, even for submersible sewage pumps requiring substantial flow rates.
Our auto coupling set, also referred to as a guide rail system, features a meticulously designed slide rail assembly, facilitating effortless pump elevation or descent within a sump or chamber. This design allows for maintenance without the hassle of disconnecting fittings, fasteners, or pipework. The standard kit includes a base, pump adaptor/guide hook, and a superior upper rail positioning bracket, enhanced with lifting chains and shackles. Depending on the model, the pump navigates one or two rails, guiding it to its designated location with precision, ensuring a perfect seal or seamless removal from the system.
Our guide rail systems come meticulously equipped with the following attachments:
Sturdy fixing stand
Secure locking arrangement
Durable bend pipe
