Principle of operation
 

Description
Busch Puma boosters are air-cooled, positive displacement rotary lobe blowers intended for use in conjunction with a backing pump. They are designed for vertical flow preventing material build-up within the booster during periods of shutdown. Puma Roots pumps have no mechanical bypass, therefore, the maximum allowable differential pressure between inlet and discharge must be respected. Eight sizes are available from 350 to 1520 CFM.

Features

 Sealing rings prevent oil from entering pumping
