Submersible pumps are mainly installed in vertical, horizontal, inclined, floating, borehole, suspended and coupled types, etc. The specific selection needs to be determined according to the application scenarios (e.g., deep wells, sewage disposal, agricultural drainage and irrigation), spatial conditions, and maintenance requirements.

 

Centrifugal pump is a kind of pump that utilizes the centrifugal force generated when the impeller rotates to transport the liquid, the main feature is that the liquid flow under the action of centrifugal force for radial flow, high head, high efficiency and energy saving; in the use of the valve to be used to shut down the start, this time the power is relatively small, and the motor is not easy to be burned.

 

Mixed flow pump from the shape, structure are between centrifugal pumps and axial pumps, mixed flow pump working principle is through the high-speed rotation of the impeller, both centrifugal pumps produce centrifugal force, but also has the axial pump thrust force, mixed flow pumps rely on the mixing of these two forces pumping. Mixed flow pump performance is also between the two, it and the centrifugal pump compared to the head is low, the flow rate is large, and the axial pump compared to the head is high, the flow rate is small. Axial pump head range is generally within 10 meters, mixed flow pump is generally within 10 to 20m, single-stage centrifugal pump head can reach more than 20m.

 

 

Mixed flow pump impeller outflow direction and pump performance between centrifugal pumps and axial pumps, the main features of high-performance flow and head combination, mixed flow pumps in the start-up should be selected to open the gate to start.
