Vortex Pump

A vortex pump (also called a vortex pump) is a vane pump. It is mainly composed of impeller, pump body and pump cover. It is suitable for occasions requiring small flow (1 to 40 cubic meters per hour) and high lift (up to 250 meters).

A vortex pump is a vane pump. It is mainly composed of impeller, pump body and pump cover. The impeller is a disc with blades radially and evenly arranged around the circumference. An annular flow channel is formed between the pump body and the impeller, and both the suction port and the discharge port are at the outer circumference of the impeller. There is a partition between the suction port and the discharge port, thereby separating the suction port and the discharge port.
