Mechanical Booster System

Vacuum Boosters are designed to be power efficient. Very often a combination of vacuum booster and suitable back up pump result in reduced power consumption per unit of pumping speed. They provide high pumping speeds even at low pressures. The vacuum booster is a dry pump, as it does not use any pumping fluid. It pumps vapor or gases with equal ease. Small amounts of condensed fluid can also be pumped.

Major Advantages:

Can be integrated with any installed vacuum systems such as steam ejectors, water ring pumps, oil sealed pumps and water ejectors, etc
Boosters increase the working vacuum of the process, in most cases very essential for process performance and efficiency.
It has very low pump friction losses, hence requires relatively low power for high volumetric speeds. Typically, their speeds, at low vacuums are 20-30 times higher than corresponding vane pumps/ring pumps of equivalent power.
Vacuum boosters do not have any valves; rings, stuffing box, etc therefore do not demand regular maintenance.
Due to vapor compression action by the booster, the pressure at the discharge of booster is maintained high, resulting in advantages such as low back streaming of prime pump fluid, effective condensation even at higher condenser temperatures and improvement of the back up pump efficiency.

The mechanical booster system is available in a combination as follows:
