Vacuum Boosters

Positive displacement vacuum pumps/booster are used to create low vacuums. This type of vacuum booster, expands a cavity and allows the gases to flow out of the sealed environment or chamber. After that, the cavity is sealed and causes it to exhaust it to the atmosphere.

Our mechanical Vacuum Booster are positive displacement pumps with two figure eight shaped impellers rotating in opposite directions inside the casing. As each lobe of an impeller passes the blower inlet, it traps a quantity of air equal to exactly one fourth the displacement of the blower.

This entrapment occurs four times per revolution. The entrained air is forced around the case to the blower outlet. Timing gears accurately position the impellers in relation to each other to maintain the minute clearances so vital to the high volumetric efficiency of the pump.

• Boosts vacuum levels of backing pumps, thereby reducing process temperature
• Boosts volumetric displacement, thereby reducing process time
