Due to their high pumping speed and ultimate pressure, Panda WV vacuum boosters increase the performance of vacuum systems. Available in six different sizes, Panda WV vacuum boosters can be designed to perfectly suit all low and medium vacuum applications in which the performance of the backing pump needs to be significantly increased or optimally adapted to the process. The Panda WV 1500 – 4500 B/C are the three larger vacuum boosters in this series.

Panda WV 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 pump combinations can generate a suction performance which would otherwise only be possible with a large number of backing pumps.

Thanks to the integrated bypass valve, Panda WV vacuum boosters achieve a high pumping speed even in rough vacuum applications. It reliably protects pump and motor against overloading, and allows the Panda WV to be switched on together with the backing pump even at atmospheric pressure without further action. A processrelated, sudden pressure increase due to a greater gas flow can be easily handled by the bypass valve in continuous operation.

Panda WV vacuum boosters can be flanged directly onto the backing pump or at any other position on the system due to our large and specially designed portfolio of adapters.

Technical specifications
Within the housing of Panda WV 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 compression chamber. The synchronous rotation of the two lobes is driven by a pair of gear wheels separated from the process chamber. The integrated bypass valve, which comes as standard, enables an operation around atmospheric pressure or at low vacuum without the need for a special controller. Busch vacuum boosters are driven by a directly coupled electric motor of efficiency class IE3.
