Modular designed Busch R5 oil sealed rotary vane vacuum pumps are single stage, air-cooled, 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.
Rotation of the pump rotor, which is mounted eccentrically in the pump cylinder, traps entering vapor between rotor vane segments. As rotation continues, vapor is compressed and discharged into the exhaust box.
Vapors then pass through several stages of internal oil and mist eliminators to remove lubricating oil from the exhaust. Separated oil is returned to the oil reservoir. An internal anti-suckback valve prevents the pump from rotating backwards.
A built-in gas ballast permits pumping with high water vapor loads and provides oil drying for maximum performance.
