QL Series Vacuum-Assisted Self-Priming Pump

The ZW series is a heavy-duty industrial impurity pump that integrates self-priming capability and non-clogging sewage handling into a single unit. Utilizing an axial backflow external-mixing system with an optimized pump casing and impeller design, it eliminates the need for a foot valve or initial priming water. The pump is engineered to transfer liquids containing large solids and long fibers smoothly. It features a simplified structure, reliable self-priming performance, high energy efficiency, and easy maintenance, making it an ideal choice for municipal sewage, aquaculture, paper pulp, chemical processing, and power plant suspension transfers.

• Self-Priming Capability: Utilizes an axial backflow external-mixing system. No foot valve or initial priming water required after first-time filling.
• Non-Clogging Hydraulic Design: Large-passage impeller allows smooth transfer of fluids containing solid particles and long fibers.
• Serviceability: Equipped with an independent cleanout cover plate at the front of the pump casing for quick sediment removal without dismantling pipes.
• Material & Motor Options

Optional 304/316 SS and explosion-proof motors for hazardous fluids.
