RZ 6

These powerful rotary vane pumps feature an unusually compact design and low weight for pumps of this capacity. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium to increased gas flow rate. The PC 3 rotary vane pumping unit, with GKF 1000i cold trap at the inlet, helps the pump handle large amounts of condensable vapors. The PC 3 pumping unit is compact, user-friendly, and well-arranged, with an oil mist filter at the outlet, a valve, and a T-connection for a gauge. Various packages including pump, oil mist filter, etc. are available.

Performance features

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
