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
These powerful rotary vane pumps feature a particularly 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. Various packages including pump, oil mist filter, etc. are available. Rotary vane pumps are used when an ultimate vacuum between a few mbar and down to 10-3 mbar has to be attained. Typical applications are degassing, lyophilization, fine vacuum distillation and drying chambers. The pumping unit PC 3 is the perfect choice for applications requiring special protection of pump and environment. Designed for the use in chemical laboratories the cold trap helps the pumps to handle large volumes of condensable vapors. The cold trap is metalized for extended coolant life and protected against implosion.
