RZ 9Rotary vane pump

Overview

  • very high flow rates even at vacuum levels approaching ultimate vacuum
  • high water vapor tolerance due to efficient gas ballast; very good ultimate vacuum even with gas ballast
  • vacuum-tight at switch-off; external anti-suckback valve not needed
  • large oil volume: Long intervals between oil changes
  • ease of maintenance due to telescopic design

Ultimate vacuum

2 x 10-3 mbar

Ultimate vacuum with gas ballast

1 x 10-2 mbar

Max. pumping speed 50 Hz

8.9 m3/h

Rotary vane pump in action

The RZ 9 is a two-stage powerful rotary vane pump for fast evacuation of vessels and at higher gas flow rates. Typical applications are lyophilization, fine vacuum distillation and drying chambers. The two-stage rotary vane pump RZ 9 is also available in various packages with matching accessories such as exhaust filter FO and valve VS 25. Rotary vane pumps are used for a process vacuum of a few mbar to 10-3 mbar.
