The HW axial-flow pump is a high-efficiency product designed based on the standard new series. It has evolved from the HB pump, with a similar structure and basic parameters designed, manufactured, and accepted according to the standards. Its performance indicators have reached international advanced levels, showing significant material-saving and energy-saving effects. The flow rate and head of the mixed-flow pump are between those of centrifugal pumps and axial-flow pumps. The HW mixed-flow pump is a horizontal, single-stage, single-suction, cantilevered volute pump. It has a small size, light weight, high flow rate, high efficiency, good cavitation performance, a wide and flat range, simple structure, easy use, and easy maintenance. The HW mixed-flow pump is suitable for transporting clear water or other liquids with similar physical and chemical properties to water.
