Puma WPA 040 - 075 A

  • Efficient:
    minimized operating costs
  • Reliable:
    robust construction, reliable under varying operating conditions, solid lobe design for high particle tolerance
  • High Performance:
    high pumping speed due to excellent volumetric efficiency
  • Easy Servicing:
    minimal maintenance
     

Due to their high pumping speed and ultimate pressure, Puma WPA vacuum boosters increase the performance of vacuum pumps. Available in various sizes, Puma WPA vacuum boosters can be designed to perfectly suit all rough and medium vacuum applications in which the performance of the backing pump needs to be significantly increased or optimally adapted to the process. The Puma WPA 040 – 075 A are the three smaller vacuum boosters in this series.

Puma WPA are the perfect vacuum boosters for all types of backing pumps. When using a combination of backing pump and vacuum booster, the pumping speed and ultimate pressure of a vacuum system can be increased by up to a factor of 10. As a result, these combinations can generate a suction performance which would otherwise only be possible with a large number of backing pumps.

Puma WPA vacuum boosters can be controlled using a pressure switch that activates the vacuum booster of the backing pump if it has achieved the optimum pressure. Alternatively, the Puma WPA vacuum boosters are also available in versions that are controlled by frequency converters.

Puma WPA vacuum boosters can be installed at any stage of the system.

Technical specifications
Within the housing of Puma WPA vacuum boosters, two lobes rotate synchronously. Due to the special profile of the lobes and their precise manufacturing, they do not come into contact with each other or the housing. Thus, no lubricants or operating fluids are required in the process chamber. The two lobes are driven by a pair of gear wheels separated from the process chamber. Busch vacuum boosters are driven by a directly coupled electric motor of efficiency class IE3, for electrical network worldwide.
