Modular designed Busch R 5 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
. 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.
• Compact, simple design for easy installation and low maintenance
• Air-cooled, requiring no water
• Direct drive, eliminating belts and gears to loosen or wear
• Oil mist eliminator for oil-free exhaust
• Quiet operation
The Busch Huckepack Mark 4 vacuum pump is a two-stage, Once-Through-Sealing, rotary vane design. The Mark 4 design allows engineers the flexibility and performance they need for their particular process including the choice of several sealing fluids with different vapor pressures.
The Mark 4 is available in water-cooled (single pass) or radiator-cooled versions. It reaches an end vacuum of 0.5 torr (29.9" Hg), and comes in four sizes, from 113 CFM to 444 CFM.
• Coolant temperature control system
• Optional gas ballast in bottom stage to aid in
pumping high boiling compounds
• Graphite PTFE exhaust and bypass valves
• Adjustable sealant metering pump
• Sealant reservoir and optional flushing tank for
different fluids during flushing cycle
• Wide selection of sealing fluids possible
The Busch Dolphin is designed for a wide range of industries and is able to pump gases, vapors and handle entrained liquids. It is designed for continuous operation and has an end pressure of 25 torr (29”Hg). The Dolphin is single stage, compact, direct driven, and cost effective. Eight sizes are available from 20.6 to 271 ACFM pumping speed.
