Pumps - Visual Encyclopedia of Chemical Engineering

Pumps are designed to operate within a range of pressures and temperatures. Centrifugal pumps produce heat, which causes liquid expansion and possible vaporization, leading to excessive pressure. ...<< more>>

Choosing Process Vacuum Pumps | AIChE

Vacuum, or sub-atmospheric pressure, is used in a wide range of chemical processing and manufacturing applications. This article is an introduction to the main vacuum pump technologies suitable for use in the chemical process industries (CPI). ...<< more>>

Vacuum Pumps - Chemical Engineering

Equipment Design The rotors run dry within the pump housing. The gears and rotor bearings are oil-lubricated, but they are external to the pump, as shown in the schematic below to the left. ...<< more>>

Liquid Ring Pump Power Calculation - Cheresources

I'm running a 2-stage vacuum tower (upper absorber at 40 Torr, lower absorber at 10 Torr). I understand the liquid ring pump will operate much like a compressor, with the suction pressure being either 40 or 10 Torr and each obviously discharging to atmosphere (i.e. 750 Torr). ...<< more>>
