Page 9: Function
Product description Function ™ The vacuum pumps of the DuoLine are dual stage rotary vane pumps and are used primarily for rough and medium vacuum applications. The pumps are fitted with a hy- draulically controlled vacuum safety valve which, when the pump is at a stillstand, closes the vacuum chamber vacuum tight and at the same time vents the pump. -

Page 11: Connecting The Exhaust Side
Installation Connecting the exhaust side CAUTION High pressure in the exhaust line! Danger of damage to the seals and danger of the pump bursting. Observe the maximum permissible pressure of 1500 hPa (absolute), activate shut- off valves in such a way that they open before or at the same time as the pump is started. - Page 12 Installation NOTICE Excess voltage! Danger of destroying the motor. Power connections must comply with local regulations. Voltage and frequency infor- mation given on the motor rating plate must correspond to the mains voltage and fre- quency values. To protect the motor and supply cable in case of malfunction, mains fuse protection must be implemented.

Page 16: Filling Up The Operating Fluid
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. -
Page 17: Operations Monitoring (Option)
Installation Operations monitoring (Option) For operations monitoring a pressure switch can be installed on the side of the support. In case of a malfunction, e. g. pressure drop or when the pump is at rest, the contact of the pressure switch opens. The signal can be used to control external valves. Switching voltage: 5 ... -
Page 18: Operation
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). -
Page 19: Pumping Condensable Vapours
Operation Pumping condensable vapours Should the process gases contain condensable gases, the rotary vane pump must be operated with gas ballast (i.e. with an open gas ballast valve). NOTICE Bad final vacuum and damage to the pump! Danger of condensation and corrosion due to exceeding the water vapour compatibility during operation without gas ballast or in case of insufficient supply of flushing gas. -
Page 20: Topping Up The Operating Fluid
Operation NOTICE Flushing gas pressure higher than allowed endangers the operational reliability of the pump. The power input of the pump, the temperature and the ejection of operating fluid will in- crease. Observe the maximum permissible flushing gas pressure. ... -
Page 21: Switching Off The Pump
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. -
Page 22: Maintenance
Maintenance Maintenance Precautions DANGER Strong magnetic field in the vicinity of the drive system! Danger to life for persons with cardiac pacemakers when the drive system is disassem- bled. Persons with cardiac pacemakers must not enter the area (≤ 2m) of the magnetic field. - Page 23 Checklist for inspec- Certain maintenance and overhaul work should only be performed by Pfeiffer Vacuum 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.

Page 24: Changing The Operating Fluid
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. - Page 25 Maintenance Fig. 14: Draining the operating fluid Screw in operating fluid drain screw 198; pay attention to O-ring. Screw in operating fluid filler screw 200. Allow pump to run for a maximum of 5 seconds with the vacuum flange open. ...

Page 26: Changing The Kind Of Operating Fluid
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. -
Page 27: Cleaning Or Changing The Silencer
Maintenance Cleaning or changing the silencer The silencer is a nozzle 44 inside the pump housing and cannot be altered; when dirty it should either be cleaned or replaced. Unscrew 2 cheesehead screws 182 from the gas ballast valve housing. ... -
Page 28: Decommissioning
Replace the operating fluid. Replace the elastomer parts, with reference to DIN 7716 and the manufacturer's specifications. Follow the maintenance instructions and inform Pfeiffer Vacuum. Disposal Products or parts thereof (mechanical and electrical components, operating fluids, etc.) may cause environmental burden. -
Page 29: Malfunctions
Malfunctions Malfunctions Please note the following instructions should the pump malfunction: CAUTION Hot surface! Danger of burns if hot parts are touched. The surface temperature of the pump may rise above 105 °C in case of malfunction. Carry out work on the pump only after it has cooled to a safe temperature. NOTICE Motor overload! Depending on the malfunction (e.g. -
