Introducing the WQ Series Submersible Sewage Pump—a marvel of engineering featuring extraordinary energy-saving capabilities, wrap-proof design, non-block technology, along with auto-installation and auto-control features. This pump exhibits a remarkable proficiency in the drainage of solid grains and long fiber waste, ensuring uninterrupted operations.
The pump's unique impeller structure, complemented by an innovative mechanical seal, allows for the seamless transportation of liquids containing solids and long fibers. Unlike conventional models, this pump's impeller boasts a single or dual flow-path form, akin to an elbow of the same section, delivering superior flow-through performance. It is paired with a well-designed turbine room, leading to exceptional effectiveness. The impeller undergoes dynamic and static balancing tests, ensuring stable and reliable operation. This series is renowned for its advanced hydraulic performance, high efficiency, diverse structures, and multiple installation modes, which simplify pump station setups and reduce investment costs.
The impeller, a pivotal component of a centrifugal pump, is where the magic happens. As the liquid is directed towards the center of the rotating impeller, it is swiftly captured by the vanes, accelerating to higher velocities before being discharged by centrifugal force into the casing. The collection chamber ingeniously converts kinetic energy into head or pressure. The pump's performance and efficiency are largely dictated by the impeller type. We offer various impeller designs to meet diverse application needs.
For our submersible sewage pumps, we provide a range of impeller options, such as the vortex type, semi-open channel type, non-clog closed type, and the innovative non-clog impeller with cutter type.
The submersible sewage pump is powered by a robust copper electric motor and features a UL water-proof armored cable, ensuring a stable power supply for handling large flow rates efficiently.
Our auto coupling set, or guide rail system, consists of a slide rail assembly that facilitates the effortless lifting or lowering of a pump within a sump or chamber. This is vital for cleaning or maintenance tasks, eliminating the need to disconnect fittings, fixings, or pipework. A standard kit includes a base ("duckfoot" or "pedestal"), pump adaptor/guide hook, and an upper rail positioning bracket. Lifting chains and shackles are part of the set. Depending on the model, the pump is directed smoothly by one or two rails, not included, to its proper seating location or for easy removal from the system/sump.
The guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
