Vacuum Booster

vacuum-boosterWhen the working pressure is under 100 mbar (A), you ought to consider the use of a vacuum booster. In this way you will be able to reduce the evacuation time and the power consumption drastically.

For example, by a suction pressure of say 33mbar (A) and a volume flow of 1800 m^3/h you can use a liquid ring vacuum pump with an installed power of 55kW.

With one of our boosters you will achieve, by this working pressure, a compression ratio of 1:5. In this example it means that the volume flow of 1800m^3/h will be compressed 5 times from 33mbar (A) to an outlet pressure from the booster at 165 mbar (A). By this model, you can re-engineer to a new liquid ring vacuum pump, that now though will need a suction capacity of 360 m^3/h.

By combining a liquid ring vacuum pump with a booster, you will need 11 kW for the 360 m^3/h vacuum pump and 5,5 kW at the 2000m^3/h booster. That means a saving in power of 38, 5 kW when comparing with one big liquid ring vacuum pump without booster.

Working 6000 hours a year means saving 228.000 kWh on electricity. The use of water will be less than a half compared to the bigger liquid ring vacuum pump, and so will the evacuating time in the middle-high vacuum area.

Normally the boosters can be used in connexion with liquid ring vacuum pumps, rotary vane pumps and screw pumps acting as backing pumps.

Gugliotta & Co. offers boosters with suction capacity of up to 15.500 m^3/h. besides we also offer complete booster solutions including control system and plant re-engineering.
