Mechanical Vacuum Boosters
Mechanical Vacuum Boosters, also referred to as Mechanical Vacuum Booster Pumps are used in a growing number of applications where fast pump down times are required, and environment or energy usage concerns, rule out any alternative pump selection.
Mechanical Vacuum Boosters are dry pumps that meet most of the ideal vacuum pump requirements. They work on positive displacement principle and are used to boost the performance of water ring /oil ring /rotating vane /piston pumps and steam or water ejectors. They are used in combination with any one of the above mentioned pumps, to overcome their limitations.
Vacuum booster pumps offer very desirable characteristics which make them the most cost effective and power efficient option.
TMC Fluid Systems designs and configures Booster Pumps that enhance the performance, ultimate vacuum and pumping speed of the following types of pump:
- oil-sealed
- water-ring
- dry vacuum types of mechanical pumps
all of which are widely used in the industry.
Advantages:
- High vacuum of the order of 0.001 Torr or better
- High pumping speeds at low pressures. Speed is boosted by 3-10 times or more
- Relatively lower power consumption for such performance boosting
- Considerable reduction in pump down time of vacuum machines
- Prevents oil back-streaming from rotary pump
- Dry Pumping - Suitable for Gas / Vapor Loads.
- Boosts vacuum performance of existing plant & machinery
Clients use vacuum boosters for:
- Heat Treating
- Hardening
- Melting
- Optica Coating
- Metallizing
- Degreasers
Operating Principle of Mechanical Vacuum Boosters
 |
Vacuum Boosters 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.
Key Features
- Boosts vacuum levels of backing pumps, thereby reducing process temperature
- Boosts volumetric displacement, thereby reducing process time
