ZW series self-priming centrifugal pump efficiently and reliably conveys water from rivers, ponds, and other sources to farmland, helping users reduce irrigation time and save labor. This is achieved through its high-efficiency delivery, strong self-priming capability, clog-free operation, and low energy consumption.
This pump features a liquid-tank gas-liquid separation structure that retains water after initial filling. In other words, it can restart operation without needing to replenish water. This equipment is particularly suitable for peak farming seasons, extending irrigation duration while reducing labor requirements. thus lowering production costs and expanding irrigated acreage. During rainy seasons, the equipment can also operate in reverse to drain accumulated water from fields, effectively preventing flood damage to crops and significantly mitigating economic losses.

ZW series horizontal centrifugal pumps feature strong self-priming capability with a self-priming height up to 7 meters. This eliminates the need for constructing elevated reservoirs or digging wells, enabling stable direct conveyance of water from low-level sources such as rivers or canals to farmland. This significantly reduces construction costs. To handle liquids containing solid particles up to 60% of the pump inlet diameter, this pump employs widened flow channels and a semi-open impeller. This design enables direct pumping of silt and other impurities, reducing downtime for cleaning and increasing irrigation time.
It also utilizes a special axial recirculation external mixing impeller channel technology. This ensures smooth passage of sewage through the pump body, eliminating the need for foot valves or priming pipes. Particularly suited for pond aquaculture, municipal sewage projects, papermaking, textiles, and similar fields, it stands as the ideal impurity pump. To achieve significant energy savings, the ZW series centrifugal pump employs an optimized hydraulic model, yielding 3%-5% higher efficiency than standard self-priming pumps. Paired with a high-efficiency motor, it delivers over 8% overall energy savings, substantially reducing consumption and enhancing economic benefits.
With its no priming required, high self-priming lift, wide flow passage, and ability to handle impurities features, the ZW self priming pump is the ideal choice for diverse agricultural irrigation scenarios involving dispersed water sources, sandy water conditions, and small-scale fields. It significantly boosts irrigation efficiency, ensures stable crop growth, and reduces production costs.
