Working Flow Rate: How to Compare Vacuum Pumps .

Examining the performance curves reveals an interesting pattern not captured by the pumps' specifications. Pump X loses almost two-thirds of its specified pumping speed before it reaches a vacuum level of 100 mbar—the vacuum level achieved by an effective house vacuum system, and a suitable level for vacuum filtration precisely because it minimizes evaporation.

The Condensation Effect on Liquid Ring Vacuum Pumps

The Condensation Effect on Liquid Ring Vacuum Pumps

The liquid ring vacuum pump is a constant volume device, which means that at a given speed the volume of gas taken in will be a constant. If the gas steam coming to the vacuum pump contains a condensable vapor, and the vapor is condensed before it is drawn into the bucket of the liquid ring pump, the gas will occupy less space than it had .
