Multistage Pump

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.
