What are the categories of pumps?

Water pump is a kind of mechanical equipment used to transport liquid. According to different working principles and uses, it can be divided into the following categories:

1. Common centrifugal pump: Centrifugal force is generated by the rotation of the rotor, and the liquid is sucked from the low pressure area, and then transported to the high pressure area through the pipeline. Commonly used in industry, construction, agriculture and other fields.

2. Submersible pump: Designed to work underwater, it can pump liquid from underground locations such as deep water wells or pools. Commonly used in water supply, irrigation, drainage and other fields.

3. Mixed flow pump: It combines the characteristics of centrifugal pump and axial flow pump, has higher flow rate and lower head, and is widely used in water treatment, farmland irrigation and other fields.

4. Axial flow pump: The liquid flows in the axial direction of the pump, mainly used for the transportation of large amounts of liquid, such as drainage, cooling, etc.

5. Vortex pump: liquid is pumped into the pump by vortex and centrifugal force, which is often used in sewage treatment, chemical industry and other fields.

6. Jet pump: Use high-speed jet of liquid to generate negative pressure and pump the liquid into the pump, usually used in water supply systems or drainage systems.

7. plunger pump: through the plunger movement in the pump cavity, to achieve the suction and discharge of liquid, commonly used in high pressure delivery, chemical and other fields.

In addition to the above common water pump categories, there are other special types of water pumps, such as slurry pumps, air pumps, vacuum pumps, etc. According to different engineering needs and use environments, it is very important to choose the appropriate water pump type.
