In combination with backing pumps,
In combination with backing pumps, PANDA/PUMA are perfectly suited for all applications that require high pumping speeds at a defined working pressure.
Busch vacuum boosters are available in a large number of sizes. This allows pumping speeds and ultimate pressures to be tailored exactly to the process conditions.
In contrast to PUMA vacuum boosters, PANDA boosters are coming with a bypass valve as standard. Both PUMA/ PANDA series are compatible with a variable speed drive.
Within the housing of PANDA/PUMA 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.
During the rotation of the lobes, gas is transported between the lobes and the housing into the backing pump.
