Single Stage 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.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. Two-stage type: A pump with two pump chambers connected in series to increase the compression ratio is a two-stage type.
