Vacuum pump - Wikipedia

A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity....

Vacuum Pumps: Their Uses and Applications

Applications for Vacuum Pumps. Vacuum pumps are used for a wide range of applications in many different industries. Vacuum pumps remove gas from a sealed volume to leave a partial vacuum. Fluids then rush into the vacuum due to the difference in pressure gradients. There are three kinds of vacuum pumps: positive ......

Liquid Ring Vacuum Pump Operation | NASH - Gardner Denver Nash

The NASH liquid ring vacuum pump uses water or any other suitable liquid, which acts as "liquid pistons", hence the name liquid ring. 2.) It's apparent that the chambers between ... Some NASH pumps have a port plate configuration rather than conical, but the principle is the same. 4.) This diagram demonstrates what the ......

Vacuum pumps - working principles and properties - Pfeiffer Vacuum

Vacuum pumps are categorized as gas transfer pumps and gas binding or capture pumps. While gas-displacement vacuum pumps can be used without limitation, gas-binding vacuum pumps have a limited gas absorption capacity and must be regenerated at certain process-dependent intervals. Gas- displacement pumps ......

Deep Vacuum Principles and Application - Alltemp

A vacuum pump creates a void toward which the system pressure flows. 2. As pressure decreases in the system during evacuation, flow also decreases. Therefore, it is. IMPOSSIBLE to increase the pressure or flow through a gauge port with a larger pump....

Rotary Vane Vacuum Pump - Principles of Operation | Dekker ...

The operating principles for the rotary vane vacuum pump for wet applications are the same as the lubricated rotary vane vacuum pump. The differences include: The separator for the wet applications pump includes baffling to help the water settle out of the oil. The large sight glass gives visible indication of water in the oil....

Design / Operating principle - Pfeiffer Vacuum

4.4.1 Design / Operating principle. Two parallel bearing-supported, intermeshing screw rotors (3) having opposite threads synchronously and contactlessly counter-rotate in a cylindrical housing (2) that tightly encloses them, and together form a multi-stage pump. Because of the counter-mesh of the two rotors, the volumes ......
