    application-oriented thanks to an optional variable speed drive
     

Due to their high pumping speed and ultimate pressure, Puma WP vacuum boosters increase the performance of vacuum pumps. Available in various sizes, Puma WP 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 WP 1250 – 4500 B2/D2 are the three largest vacuum boosters in this series.

Puma WP 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 WP 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 WP vacuum boosters are also available in versions that are controlled by frequency converters.
Puma WP vacuum boosters can be flanged directly onto the backing pump or at any other position on the system thanks to our large and specially designed portfolio of adapters.

Technical Specifications

Technical specifications
Within the housing of Puma WP vacuum boosters, two lobes rotate synchronously. Due to the special profile of the lobes and their precise manufacturing, they do not come in 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. Puma vacuum boosters are available with pressure switch. A frequency converter can also be used to adapt the performance of the vacuum booster to customer requirements. Busch vacuum boosters are driven by a directly coupled electric motor of efficiency class IE3, for electrical network worldwide.
