1 R5 Series Vacuum Pumps and R5 Brochure 2/26/01 5:03 PM Page 6R5 AdvantagesR5 Series Rotary VaneVacuum Pumps & Systems Compact, simple design for easy installation and low maintenance Air-cooled, requiring no water Direct drive, eliminating belts and gears to loosen or wearThe modular designed Busch R5 Series rotary vanevacuum Pumps are single stage, air-cooled, and directdriven. This oil-recirculating design is one of thesimplest and most reliable Vacuum Pumps available onthe world market. These rugged Pumps are used in avariety of industries such as packaging and foodprocessing, rubber molding, thermoforming, printedcircuit board testing, hospitals, laboratories, robotics, Vacuum lamination, printing, and many others. Displacements range from 3 to 1130 CFM. Threemodels are available: the RC for applications to 15 torr( "Hg); the RB for applications to 2 torr ( "Hg);and the RA for applications to torr ( "Hg).

Vapors thenpass through several stages of internal oil andmist eliminators to remove of lubricatingoil from the exhaust. Oil is then returned tothe oil reservoir. Additional featuresinclude an automotive type spin-on oilfilter, and a built-in inlet anti-suckbackvalve that prevents the pump fromrotating backwards.
