What types of water pumps are suitable for annular pump bodies?

Water pumps are a large category of mechanical equipment, suitable for various scenarios. However, water pumps also have different specifications, sizes, functions, etc. under different scenarios.
The water pumps are different, so the pump body accessories used are also different. The annular pump body is one of the common categories. In different water pumps, the functions displayed by its existence are also different.

Such as vortex pumps

The pump body part of the vortex pump has a nearly annular structure. It is mainly composed of a pump body, an impeller, a pump cover, etc. Its working principle is that when the impeller rotates, a vortex motion is generated in the annular flow channel, so that the liquid is sucked in and thrown out in the annular space many times, so that the pump body of some shielded pumps also has an annular structure.

There is also a shielded pump

Its motor and pump body are combined together, and the pump body part has an annular liquid flow channel. It drives the liquid in the annular space through the impeller, and due to the integrated design of the motor and the pump, it has good sealing and can effectively prevent leakage. It is often used in occasions with strict leakage requirements, such as conveying toxic and corrosive liquids. Energy transmission and liquid delivery. This type of pump is characterized by small flow and high head, and is often used in the chemical, pharmaceutical and other industries to transport viscous liquids or liquids containing a small amount of solid particles.

In addition, there are annular vacuum pumps whose pump bodies are annular. Its working principle is to use the rotation of the eccentric rotor in the annular pump body to make the volume of the working chamber change periodically, thereby realizing the suction, compression and exhaust process to achieve the purpose of vacuuming. This type of pump is widely used in vacuum systems in chemical, electronic and other industries.
