Puma WP 0250 / 0500 D2/D4

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 Puma WP 0250 D and WP 0500 D are the two smallest vacuum boosters in this series. The WP 0250 D4 and WP 0500 D4 versions are characterized by a particularly high differential pressure.

Puma WP vacuum boosters are perfect for all types of backing pumps. When used as a combination of a backing pump and a 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 lobe booster once the backing pump has achieved the optimum pressure.
Alternatively, the Puma WY is also available in versions that are controlled by frequency converters.

Puma WP vacuum boosters can be flanged directly onto the backing pump or in any other position on the system.

Technical specifications
Within the housing of Puma WP vacuum boosters, two lobes rotate synchronously. Due to the special profile of the rotating lobes and their precise manufacturing, they do not come into contact with each other or the housing. This allows for pumping without any operating fluids. The synchronous rotation of the two lobes 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.

Vacuum boosters from Busch
In addition to the Puma WP series, Busch also manufactures other rotary lobe vacuum boosters in a range of sizes. When used on vacuum systems, they cover virtually all industry applications including research and science sectors. Contact a knowledgeable Busch application specialist for additional information.
