Product description The rotary vane pump is an oil-sealed rotational displacement pump. The pumping system is made up of the housing, the eccentrically mounted rotor, and the centrifugally- and spring-loaded radially sliding vanes, which divide the suction chamber into multiple chambers. The volume of each chamber changes periodically as the rotor rotates.
► Take particular care and pay special attention when transporting products manually. ► Do not stack the products. ► Wear protective equipment, e.g. safety shoes. Pfeiffer Vacuum recommends keeping the transport packaging and original protective cov- General information regarding safe transport 1. Observe the weight specified on packaging.

Transportation and Storage Procedure 1. Fill the vacuum pump with operating fluid up to the upper edge of the sight glass. 2. Close both connection flanges and all openings on the vacuum pump. 3. Make sure that the gas ballast valve is closed. 4.
Property damage from contaminated gases Pumping down gases that contain impurities (condensate, particles) damages the vacuum pump. ► Use suitable filters or separators from the Pfeiffer Vacuum range of accessories, to protect the vacuum pump. Installation and operation of accessories Pfeiffer Vacuum offers a series of special, compatible accessories for its rotary vane pumps.
6. Support or suspend the piping to the vacuum pump so that no piping system forces act on the vacuum pump. 7. Connect both flanges with a circlip. 8. Use a separator or filter from the Pfeiffer Vacuum line of accessories if necessary.
Installation Fig. 7: Exhaust connection with flange connection 1 Exhaust line Centering ring with nozzle and O-rings 2 Protective cap Circlip Procedure 1. Remove the protective cap from the exhaust flange. 2. Observe the centering ring with nozzle including the corresponding O-rings (2×). 3.
Installation NOTICE Property damage from the voltage range being set incorrectly Recommissioning after longer downtimes of the vacuum pump or after changing the oil requires the current settings to be checked. ► Before switching the vacuum pump on each time, check the currently set voltage range. ►...
Risk of damage due to the use of non-approved operating fluid Product-specific performance data are not achieved. All liability and warranty claims against Pfeiffer Vacuum are also excluded. ► Only use approved operating fluids. ► Only use other application-specific operating fluids after consultation with Pfeiffer Vacuum. 26/60...
The type of operating fluid specified, as well as the filling quantity for the entire rotary vane vacuum pump, are shown on the rating plate. Only the operating fluid used during initial installation is permissi- ble. Subsequent change is possible only after consultation with Pfeiffer Vacuum. Approved operating fluids ●...
Operation 6 Operation 6.1 Putting the vacuum pump into operation WARNING Danger of poisoning due to toxic process media escaping from the exhaust pipe During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process media.
Operation NOTICE Risk of damage to the drive from increased motor current consumption At an intake pressure of approximately 300 hPa and under unfavorable operating conditions (such as for example exhaust side counterpressure), the power input exceeds the rated current. ►...
Operation geöffnet/ open geschlossen/ closed Fig. 11: Gas ballast valve Behavior with process gases with condensable vapors ► Operate the vacuum pump with gas ballast, i.e. with the gas ballast valve open. Open gas ballast valve ► Rotate knob on the gas ballast valve to the left to open, into position “1”. Close gas ballast valve ►...
► Shut off the intake line with an additional shut-off valve, after the vacuum pump is switched off during longer venting operations. Pfeiffer Vacuum rotary vane pumps have an integral vacuum safety valve on the intake side. The vac- uum safety valve automatically closes from a differential pressure of ≥250 hPa between the exhaust and intake sides, when the vacuum pump is switched off, and vents the vacuum pump.
► Dismantle the vacuum pump for inspection, away from the system if necessary. NOTICE Danger of property damage from improper maintenance Unprofessional work on the vacuum pump will lead to damage for which Pfeiffer Vacuum accepts no liability. ► We recommend taking advantage of our service training offering.
You can carry out maintenance work at Maintenance Level 1 yourself. We recommend Pfeiffer Vacuum Service for carrying out maintenance work of Maintenance Level 2 and Maintenance Level 3 (revision). If the required intervals listed below are exceeded, or if mainte- nance work is carried out improperly, no warranty or liability claims are accepted on the part of Pfeiffer Vacuum.
Should process conditions change, you can convert to a different operating fluid type. Safety data sheets You can obtain the safety data sheets for operating fluids from Pfeiffer Vacuum on request, or from the Pfeiffer Vacuum Download Center.
You can determine the degree of aging of P3 operating fluid in clean processes using the color chart (in accordance with DIN 51578). The supplementary sheet with the document number PK0219 can be ob- tained from the Pfeiffer Vacuum Download Center. Prerequisites ●...
