Page 9: Function
Product description 4.2 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 hydraulically 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. -

Installation 5 Installation 5.1 Setting up the pump Installation location Observe the following requirements when setting up the pump: • Note the load-bearing capacity of the mounting surface. • Maximum installation altitude 2000 m (above mean sea level) • Permissible ambient temperature: +12 ... +40°C •... -
Page 11: Connecting The Exhaust Side
Installation 5.3 Connecting the exhaust side CAUTION High pressure in the exhaust line! Danger of damage to the seals and danger of the pump bursting. Install the line without shut-off valves on the exhaust side. If there is danger of a build-up of excess pressure (> 1500 mbar abs.) in the lines, observe all official accident prevention safety regulations. - Page 12 Installation 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. If necessary, dismantle the pump from the installation for inspection.

Page 15: Filling Up The Operating Fluid
Pumps for special applications (e.g. for pumping corrosive gases) can be operated with other operating fluids. These must be defined in accordance with Pfeiffer Vacuum specifications before initial assembly and ordered separately. Permissible operating fluids • P3 (Standard operating fluid) •... -
Page 16: Operations Monitoring (Option)
Installation 5.6 Operations Monitoring (Option) A pressure switch can be installed on the side of the support to monitor the oil pressure of the rotary vane pump during operations. By pressure drop and when the pump is at rest, the contact of the pressure switch opens. The signal can be used to control external valves. -
Page 17: Operation
Operation 6 Operation 6.1 Before switching on the pump Check the operating fluid level in the sightglass. Compare the voltage and frequency information on the rating plate with the mains voltage and frequency values. Check that the exhaust connection allows free flow (max. permissible pressure 1.5 bar absolute). - Page 18 Set the amount of flushing gas on site. Connect flushing gas at the flushing gas connection. Set flushing gas pressure; maximum pressure 1.5 bar (absolute). – Select the type and amount of flushing gas depending on the process; consult Pfeiffer Vacuum if necessary.

Page 19: Switching Off The Pump
Operation 6.4 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 differ- ential pressure between the exhaust side and the intake side is ≥ 250 mbar, then the valve closes automatically and vents the pump when the pump is switched off. -
