Puma WPA 0040 - 0075 A

Higher pumping speed and improved ultimate pressure: Puma WP vacuum boosters increase the performance of your vacuum system, making it more efficient and economical. Available in nine different 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 must be drastically increased or optimally adapted to the process.
The three Puma models WP A040 A to WP A075 A achieve pumping speeds of between 3,850 and 7,350 m3 /h at 50 Hz, and between 4,700 and 8,950 m3/h at 60 Hz.

Puma WP vacuum boosters are perfect booster pumps for all types of backing pumps. When used in combination of backing pump and booster pump together, they are capable of increasing the pumping speed and ultimate pressure by a factor of 10. As a result, these pump combinations can generate a suction performance which would otherwise only be possible with a large number of backing pumps.

The Puma WP can be controlled using a pressure switch that activates the vacuum boosters of the backing pump if it has achieved the optimum pressure. Alternatively, the Puma WP is also available in versions that are controlled by frequency converters. Puma WP vacuum boosters can be installed at any stage of the system.

Technical specifications
Within the housing of Puma WP vacuum boosters, two pistons rotate synchronously. Thanks to the special profile of the rotating pistons and their precise manufacturing, they do not come into contact with each other or the housing. This makes it possible to pump a medium without the need of any operating fluids. The synchronous rotation of the two rolling pistons is driven by a pair of gear wheels located on the shaft ends in the gearbox and separated from the compression chamber. The vacuum boosters are driven by a directly flanged electric motor of efficiency class IE2.

Vacuum boosters from Busch
In addition to the Puma WP series, Busch also manufactures other vacuum boosters in a range of sizes. When used on vacuum systems, these cover virtually all applications in industry, as well as the research and science sectors. Contact us. Our application specialists are happy to advise you.
