WQ Large scale sewage pump is a new generation of pump products developed based on the introduction of advanced foreign technology and combined with the usage characteristics of domestic pumps. It features significant energy-saving effects, anti-clogging, non-blocking, automatic installation, and automatic control. It demonstrates unique effectiveness in discharging solid particles and long-fiber waste.This series of pumps adopts a unique impellr structure and a new type of mechanical seal, which can effectively transport solids and long fibers.Compared with traditional impellers, the impeller of this pump adopts asingle-channel or double- channel design. It is similar to a pipe with thesame cross-sectional size, ensuring excellent flow performance. Combined with a well-designed volute, this pump achieves high efficiency. The impeller undergoes dynamic and static balance testing, ensuring no vibration during operation.
