Installation and operation of accessories Pfeiffer Vacuum pumps can be equipped with a series of adapted accessories. The in- stallation, operation and maintenance of connected devices are described in detail in the operating instructions of the individual components.
● use of the vacuum pump to generate pressure ● pumping of liquids ● the use of operating fluids not specified by Pfeiffer Vacuum ● connection to pumps or units which are not suitable for this purpose according to their operating instructions ●...
Transport and storage Transport and storage Transport Transport instructions Remove the locking cap from the vacuum and exhaust flange immediately before con- necting! – Check the cone strainer, paying attention to the O-ring. Use only the handle on the top side of the pump to lift the pump. Fig.

Installation Fuse protection The transmission power of the pump’s magnetic coupling is so great that the cou- pling is no overload protection for the motor. To protect the motor in case of malfunction, additionally provide a fuse protection in accordance with the regional regulations.
NOTICE Use approved operating fluids only! The use of operating fluids that have not been approved by Pfeiffer Vacuum shall result in a limited warranty. In such cases, it is not possible to guarantee that product-specific performance data will be achieved.
Operation Operation Before switching on the pump Check the operating fluid level in the sight glass. Compare the voltage and frequency information on the rating plate with the mains volt- age and frequency values. Check that the exhaust connection allows free flow (max. permissible pressure 1500 hPa absolute).

Operation To avoid condensation in the pump when pumping condensable vapours, air is periodi- Gas ballast valve, cally fed into the working chamber at the beginning of the compression phase via the gas standard version ballast valve 42. The gas ballast valve is closed when turning to the right to position 0 and open when turn- ing to the left to position 1.

Operation – Select the type and amount of flushing gas depending on the process; consult Pfei- ffer Vacuum if necessary. Use the proportioning screw 7.3 to set the desired amount of gas. – Closed when fully turned to the right; open when fully turned to the left. Gas ballast valve with solenoid valve To control the flow of the flushing gas externally, an electromagnetic valve can also be used as an alternative to the versions described above.
Operation Topping up the operating fluid If the operating fluid has reached its minimum filling level, the operating fluid must be topped up. The fluid can be topped up during operation in the final vacuum. Unscrew operating fluid filler screw 304. Filling up the operat- ...
Operation Switching off the pump The pump can be switched off in any pressure range. Rotary vane pumps have an integrated safety valve on the intake side. If the differential pressure between the exhaust side and the intake side is 250 hPa, then the valve clos- es automatically and vents the pump when the pump is switched off.
Maintenance Maintenance Precautions WARNING Danger of injury from moving parts! After power failure or motor shutdown due to overheating, the motor may restart auto- matically. Secure the motor so that it cannot be switched on while any work is being performed on the pump.

Certain maintenance and overhaul work should only be performed by Pfeiffer Vacuum Checklist for inspec- Service (PV). Pfeiffer Vacuum will be released from all warranty and liability claims if the tion, maintenance required, below listed, intervals are exceeded or maintenance or overhaul procedures and overhaul are not performed properly.
Depending on the applications, Pfeiffer Vacuum recommends determining the ex- act service life of the operating fluid during the first year of operation. The replacement interval may vary from the guide value specified by Pfeiffer Vacuum depending on the thermal and chemical loads, and the accumulation of suspended par- ticles and condensation in the operating fluid.

Maintenance 304/306 308/ Fig. 12: Draining the operating fluid Screw in operating fluid drain screw 308; pay attention to O-ring. Screw in operating fluid filler screw 304. Allow pump to run for a maximum of 5 seconds with the vacuum flange open. ...
Maintenance Changing the kind of operating fluid When filling up, topping up or changing the operating fluid, always use the type of oper- ating fluid indicated on the pump type plate. If, for example, amended process conditions require the use of a different operating fluid, the fluid can be changed as follows: NOTICE Changing the type of operating fluid.
Replace the radial shaft sealing rings and further elastomer parts. Replace bearings at pumps with anti-friction bearings. Follow the maintenance instructions and inform Pfeiffer Vacuum. Disposal Products or parts thereof (mechanical and electrical components, operating fluids, etc.) may cause environmental burden.
