FAQ

What is a booster vacuum pump?

A booster vacuum pump is used to enhance the performance of a backing pump. It can increase the performance of a vacuum system by up to a factor of ten. Two lobes rotate synchronously within a housing. During the rotation of the lobes, the pumped medium is transported between the lobes and the housing into the backing pump. The lobes do not come in contact with each other or the housing. Thus, no lubricants or operating fluids are required in the process chamber. A pair of gear wheels maintains precise synchronous rotor timing.

Vacuum boosters help the backing pump overcome limitations, enabling it to handle larger amounts of the pumped medium and improving overall system performance. They are used in various applications, ranging from the solar power industry to packaging.

How does a vacuum booster work?

Vacuum boosters increase the pumping speed and ultimate pressure of vacuum pumps. They can boost the performance of a vacuum pump, the so-called backing pump, by up to a factor of ten.

Vacuum boosters operate according to the proven Roots principle: Within the housing of vacuum boosters, two lobes rotate synchronously. They do not come in contact with each other or the housing. Thus, no lubricants or operating fluids are required in the compression chamber.

During the rotation of the lobes, the pumped medium is transported between the lobes and the housing into the backing pump.

The two lobes are driven by a pair of gear wheels located on the shaft ends of the gearbox and separated from the compression chamber. This maintains precise synchronous rotor timing.

Vacuum boosters work with or without a mechanical bypass valve. Without a mechanical bypass, care must be taken that the maximum permissible differential pressure between the inlet and the outlet is kept during operation.

In vacuum boosters with a bypass valve a portion of the pumped medium is diverted. Thus, the differential pressure between inlet and outlet is automatically restricted and the booster is protected against overloading.

Vacuum generation of vacuum booster pumps explained in three steps

1. Inlet

  • The pumped medium enters via the inlet.
  • Two lobes rotate synchronously within the housing.

2. Compression

  • During the rotation of the lobes, the pumped medium is trapped and transported between the lobes and the cylindrical housing.
  • No lubricants or operating fluids are needed, as the lobes do not come in contact with each other or the housing.

3. Outlet

  • The pumped medium is released into the downstream backing pump.
  • Pumping speed and ultimate pressure of the backing pump is increased.

What is the difference between a vacuum booster and a booster vacuum pump?

There is no difference. These are just two different names used to refer to the same technology.

What are the advantages and disadvantages of vacuum boosters?

Vacuum boosters from Busch are robust and energy-efficient. They have several benefits, including:

  • Nearly maintenance-free
  • Dry and contact-free compression
  • Flexible design
  • Adaptable to all types of backing pumps
  • High volumetric efficiency
