Operating Principle

Modular designed Busch R 5 oil sealed rotary vane vacuum pumps are single stage, aircooled, and direct driven. This oil-recirculating design is one of the simplest and most reliable vacuum pumps available on the world market. These rugged pumps are used in a variety of industries  such as packaging and food processing, rubber molding, thermoforming, printed circuit board testing, hospitals, laboratories, robotics, vacuum lamination, printing, and many others. Displacements range from 3 to 1130 CFM. Three models are available:
 RA for applications to 0.5 torr (29.9"Hg)
 RB for applications to 2 torr (29.8"Hg)
 RC for applications to 15 torr (29.3"Hg)

 Compact, simple design for easy installation and
