- Q1. How many types of vacuum pump are there
- Ans.
There are two main types of vacuum pumps: gas transfer pumps and entrapment pumps.
Gas transfer pumps: move gas molecules through the pump using positive displacement or momentum transfer (e.g. rotary vane pump, diaphragm pump)
Entrapment pumps: capture gas molecules by adsorption or condensation on a solid surface (e.g. cryopump, ion pump)

Centrifuge pumps use a rotating impeller to create centrifugal force, which pushes the fluid towards the outlet.
The fluid enters the pump through the suction port and is accelerated by the impeller.
As the fluid moves through the pump, the centrifugal force increases its velocity and pressure, allowing it to be discharged through the outlet...
