The multi-stage pump is a centrifugal pump that combines the inlet and outlet sections and the middle section through a pull rod. Its output water pressure can be very large, and it also relies on the rotation of the impeller to obtain centrifugal force, thereby material. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, so as to gradually obtain a high vacuum.

The multi-stage pump realizes suction, compression and exhaust by the change of the volume of the pump cavity, so it is a centrifugal pump with variable volume.

The multi-stage pump is a kind of centrifugal pump, and it also relies on the rotation of the impeller to obtain centrifugal force, thereby material. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, so as to gradually obtain a high vacuum.

Multistage pumps can be used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine and food. In many technological processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum resuspension and vacuum degassing, multi-stage pumps are widely used. It can pump out flammable and explosive gases, and also pump out dusty and water-containing gases. Therefore, the application of water ring pumps is increasing.
