For the end suction pump there are indeed many people outside the pump industry do not understand what kind of pump this is, in fact, this is a kind of structural form to name a pump, in essence, the end suction pump is a centrifugal pump, the import direction is parallel to the axis of the pump, the export direction is perpendicular to the axis. In this article, the centrifugal pump manufacturer Changsha Pump factory will give you a detailed introduction to what is the end suction pump? And a single stage pump is a kind of pump? These two questions.
The working principle of the end suction pump is to use the impeller to rotate and make the water centrifugal movement to work. Before starting, the pump shell and suction tube must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and water to do high-speed rotating movement, and the water has centrifugal movement, is thrown to the outer edge of the impeller, and flows into the pressure water pipe of the pump through the flow channel of the spiral pump shell.
End suction pump and single stage pump are not exactly the same pump, but they are a kind of centrifugal pump, the inlet and outlet are located on the same side of the pump, and the inlet end is the end of the pump, and the outlet end is the front end of the pump. Therefore, it is also called a single-ended suction centrifugal pump or a single-suction pump. The single-stage pump refers to the centrifugal pump with only one impeller. The maximum head of the general single-stage pump is only a few meters, with simple structure, stable performance, fast speed, small size, light weight, high efficiency, large flow, easy operation and maintenance and other excellent characteristics.
Therefore, although both end-suction pumps and single-stage pumps are centrifugal pumps, their structures and characteristics are different. When selecting the pump, it needs to be determined according to the specific application scenarios and needs.
