Multistage Pump

Multistage pump can be used in petroleum, chemical, machinery, mining, light industry, medicine, food and many other industrial sectors. In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing, it can pump out inflammable and explosive gases, as well as dust and water contained gases. The multi-stage pump has a wide range of applications

Multistage pump is a kind of centrifugal pump, which is composed of inlet and outlet section and middle section through pull rod. Its output water pressure can be very large, and it also depends on the rotation of impeller to obtain centrifugal force, so as to reduce the material consumption. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, so as to gradually obtain high vacuum.

Multistage pump is to achieve suction, compression and exhaust by the change of pump cavity volume, so it is a variable volume centrifugal pump.
