Rotary vane pumps

Supplier: Vacuubrand
One- and two-stage rotary vane pumps with built-in oil pump and powerful gas ballast device for outstanding water vapour tolerance. Pumps are powerful yet compact and lightweight.

  • High pumping capacity, even at low pressures
  • High vapour tolerance to water and solvents due to the large amount of gas ballast (up to 10% of the pumping capacity), quiet running and very good final pressure even with gas ballast
  • Vacuum-tight oil circuit at shutdown to prevent corrosion
  • Long oil change intervals due to large usable oil volume
  • Smallest dimensions, low weight, telescopic construction makes for easy maintenance

Delivery information: Includes the oil filled pump with switch, thermal motor protection, 2 metre long cable with plug, clamping and centering ring on the suction and discharge ports and operating manual. The pumps packages are supplied with an EU plug but a UK power cord 181-0250 could be supplied free of charge. The dirt trap is not included and has to be ordered separately.
