Why Choose Mechanical Vacuum Boosters?

When conventional vacuum pumps struggle with pumping speed at low pressures, a mechanical vacuum booster can significantly enhance the performance of the overall system. Atcorp provides mechanical vacuum booster solutions that can be selected and integrated according to the required vacuum level, pumping capacity, backing-pump configuration and process conditions.

A mechanical vacuum booster increases the pumping speed of a vacuum system by rapidly transferring large quantities of gas at low pressure.

 

Step 1 – Gas Entry
Process gas or vapour enters the booster through the suction port.

 

Step 2 – Rotor Rotation
Two precisely synchronized lobed rotors rotate in opposite directions inside the casing.

 

Step 3 – Gas Trapping
The rotating lobes trap a defined volume of gas between the rotor and casing.

 

Step 4 – Gas Transfer
The trapped gas is carried from the suction side towards the discharge side.

 

Step 5 – Pressure Boosting
The booster increases the effective pumping capacity of the backing-pump system.

Step 6 – Continuous Evacuation
The backing pump handles the discharged gas while the booster maintains high pumping speed at low pressure.

 

Because the rotors operate with small clearances and without internal pumping fluid, the booster provides dry pumping and can handle gases and vapours without introducing sealing-fluid contamination.

Faster Pump-Down

High pumping speeds help evacuate equipment faster, potentially reducing process cycle times.

 

Higher Pumping Capacity

A booster can substantially increase the effective pumping capacity of a suitable backing-pump arrangement.

 

Low-Pressure Efficiency

Mechanical boosters are particularly effective in the low-pressure range where conventional pumps can experience reduced volumetric efficiency.

 

Dry Operation

The booster pumping chamber does not require oil or another pumping fluid, supporting clean gas and vapour handling.

 

Energy Efficient

High volumetric pumping speeds combined with comparatively low power requirements can reduce energy consumption per unit of pumped volume.

 

Flexible System Integration

Boosters can be combined with oil-sealed, water-ring, dry screw and other suitable vacuum pumps.

 

Variable-Speed Operation

A suitable VFD can modify booster operating characteristics to match changing process and backing-pump requirements.

 

Low Maintenance Design

The booster has no internal pumping fluid, valves, rings or stuffing boxes, reducing routine maintenance requirements.

Mechanical vacuum boosters are normally used as part of a complete vacuum pumping arrangement rather than as standalone atmospheric vacuum pumps.

Typical System Components

  • Mechanical vacuum booster
  • Backing / fore vacuum pump
  • Inlet isolation valve
  • Non-return valve
  • Vacuum gauge or transmitter
  • Bypass arrangement
  • Variable Frequency Drive
  • Electrical control panel
  • Process condenser
  • Inlet filter
  • Vapour handling accessories
  • Nitrogen purge arrangement

 

The appropriate combination depends on the required vacuum level, pumping speed, process vapour load and type of backing pump.

Frequently Asked Questions

Find answers about mechanical vacuum boosters, their working principle, system integration, pumping performance and industrial applications.
A mechanical vacuum booster is a positive-displacement vacuum pump used with a suitable backing pump to increase pumping speed and improve vacuum performance, particularly at lower pressures.
Generally, no. Mechanical vacuum boosters are designed to operate with a suitable backing or fore pump because they are not intended to compress directly against atmospheric pressure under normal operation.
Depending on the application, a mechanical booster can be integrated with oil-sealed, water-ring, dry screw and other suitable vacuum pumps.
The primary benefits include higher pumping speeds, faster pump-down, improved low-pressure performance, dry pumping and potentially lower energy consumption per unit of pumped volume.
The booster pumping chamber operates without pumping oil or another sealing fluid. This makes it suitable for applications where dry gas and vapour handling is important.
Yes. Their dry pumping principle allows gases and process vapours to pass through without contamination from a pumping fluid. Condensers and other vapour-management equipment can be incorporated where required.
Yes. Mechanical vacuum boosters can be integrated into suitable existing vacuum systems, including systems using steam ejectors, water-ring pumps, oil-sealed pumps and other backing technologies.
Yes. Variable Frequency Drive control can be used in suitable configurations to adjust booster operation according to process and backing-pump requirements.
Atcorp can help assess your required vacuum level, pumping speed, process gas or vapour, backing-pump arrangement and operating conditions to identify an appropriate mechanical vacuum booster solution and support its supply and integration.
