Mechanical Vacuum Booster

Mechanical Vacuum Boosters are used in a growing number of applications where fast pumpdown times are required and environment or energy usage concerns rule out any alternativepump selection.Mechanical Vacuum Booster enhances the Performance, Ultimate Vacuum and Pumping speedof Oil-Sealed, Water Ring, Dry Screw and any other vacuum pumps by increasing thethroughput pumping and improving the staging ratios.As these pumps are completely dry, the process vapours can pass through the pump withoutany contamination and be collected at the discharge of the system by a vent condenser.This Offers the customers a very efficient vapour recovery management system and anenvironment friendly vacuum ecosystem.

ADVANTAGES:

• 100% Oil-Free, Dry Pumping.
• High Volumetric Efficiency Resulting In High Pump Speed At Low Pressure.
• Capacity Boosting Of 8 to 10 Times.
• Very Low Power Consumption Ratio (M3/Kw) as Opposed to Other Vacuum Pumps.Considerable Reduction In Pump Downtime By The Use Of Such Machines.
• Dry Pumping Most Appreciated For Gas/Vapour Loads.Proven Reliable Design With More Than 10,000 Pump Installations.
• Dynamically Balanced Rotors Resulting In Very Low Vibration Levels.

OPERATING PRINCIPLE:

• Vacuum Boosters are positive displacement pumps with two figure-eight shaped impellersthat rotate in the opposite direction inside the casing. As each lobe of an impeller passes thebooster inlet, It traps a defined quantity of air equal to one-fourth of the displacement of thebooster.This entrapment occurs four times per revolution. The entrained air is forced around the casingto the booster outlet. Timing gears accurately position the impeller relative to each other tomaintain the vital pre-defined clearance resulting in high volumetric efficiency of the pump.
