Oil Lubricated Vacuum Pump

A pump with two pump chambers connected in parallel to increase the exhaust volume is a one-stage type. The pump with one pump room is, of course, a one-stage type.A single-stage centrifugal pump consists of one impeller rotating on a shaft within a pump casing which is designed to produce fluid flow when driven by a motor. It is one of the simplest designs of pumps available and many variations in design exist to satisfy the duty requirements of applications.There are two basic categories of vacuum pump: Gas Transfer Pumps and entrapment or capture pumps
