mixed-flow pump

The specific speed of a mixed flow pump is higher than that of a centrifugal pump and lower than that of an axial flow pump, generally between 300-500. Its head is higher than that of an axial flow pump, but its flow rate is lower than that of a centrifugal pump. It has a smaller flow rate than an axial flow pump and a larger flow rate than a centrifugal pump. Mixed flow pumps are mainly used for agricultural irrigation and drainage, as well as urban drainage, and can be used as circulating water pumps for thermal power plants. The performance curve shape of a mixed flow pump is also between that of a centrifugal pump and an axial flow pump. For a high head mixed flow pump, the relationship between flow rate and head, flow rate and power changes similarly to that of a centrifugal pump. In use, the valve can be closed to start the pump. At this time, the power is low and the power is safe. The performance of a flow pump is also between that of a centrifugal pump and an axial flow pump. Compared with a centrifugal pump, it has a lower head and a higher flow rate; Compared with axial flow pumps, it has a higher head but a lower flow rate. For China's vast territory and complex terrain, there is an additional pump type that can be selected according to local conditions.
