Description
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.

 

Advantages
  • Compact, simple design for easy installation and low maintenance
  • Air-cooled, requiring no water
  • Direct driven, eliminating belts and gears to loosen or wear
  • Oil mist eliminator
  • Quiet operation
  • Easy exhaust filter change

 

Standard Equipment
  • IEC motor
  • Anti-suckback valve
  • Built-in exhaust filter
  • Wire mesh inlet screen
  • Non-metallic, nonasbestos vanes
  • Vibration isolators
  • Oil level sight glass

 

Operating Principle

1. Inlet
2. Rotor
3. Vane
4. Exhaust valve
5. Oil sump
6. Exhaust
7. Exhaust filter
8. Oil fill plug

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.

 

Applications
  • Vacuum packaging
  • Food technology
  • Woodworking
  • Pneumatic conveying
  • Transport and lifting systems
  • Plastics industry
