WQQG
WQQG (Power: 3kW–45kW) is specially designed for the most complex and demanding wastewater treatment conditions.
All pumps in the series are equipped with the newly developed high hardness chopper impeller, which effectively prevents clogging, reduces after-sales maintenance, and features long times service life. This series features installation dimensions identical to international brands, enabling quick pump replacement without replacing the coupling base.
It is suited for harsh sewage conditions containing high levels of fibers and big solid impurities, such as municipal wastewater treatment plants, sewage lifting pump stations, industrial sewage lifting and discharge, agricultural irrigation, and farm wastewater treatment.
Impeller Type | Core Feature | Application | Advantage | Recommended Product |
|---|---|---|---|---|
Chopping Impeller | Built-in sharp cutting edge, shear & chop sundries | Sewage, manure, fiber, cloth, plastic waste | Anti-clogging, strong cutting ability | WQQG |
Cutter Impeller | Integrated blade cutting structure | Domestic sewage, light fiber sewage | Compact structure, easy installation | |
Vortex Impeller | Vortex flow passage, no easy winding | General municipal sewage | Stable operation, long service life | WQX |
Double Channel with cover, high efficiency | Clean water, clear liquid delivery | High efficiency, high lift |
Innovative sewage pump with high reliablility and duralibity
The impeller features a semi-open, double-vane structure with a cutting edge at the axial end.Impeller works together with the fixed chopper plate on the pump casing to form a scissor-like cutting structure.The impeller rotates inside the chopper plate, effectively cutting solid and ensuring smooth passage capacity for long-fiber materials.
The pump operates overload-free at high flows. All components work together efficiently without sacrificing the pump's hydraulic performance, ensuring consistently high pumping efficiency.
Vesta's team leverages a global manufacturing footprint to provide a unique blend of rapid service.
The Material of impeller and chopper plate feature ultra-high hardness. Made of high-chromium cast iron (HRB≥600), they offer outstanding wear resistance, ensuring long service life and high cutting efficiency.
Double pass mechanical seal reduces the risk of bearing and stator failure, effectively ensuring long-term safe motor operation.
Motor components are interchangeable with other sewage pump series, such as the WQX vortex pump.
A front wear plate is installed in the pump chamber to effectively reduce the peripheral speed of long-fiber materials. The wear plate features self-cleaning relief grooves that work together with the impeller to release solids along the leading edge.
High-efficiency IE3 motor, ensuring energy-saving and reliable pump operation.
The upper end of the pump outlet can be machined to provide a mounting platform for the guide bar bracket. The outlet flange can also be drilled to standard flange dimensions, enabling quick and easy pump retrofit without the need for sump dewatering.
