Page 8: Construction And Function
Product description 4.2 Construction and function The UnoLine™/DuoLine™ pumps are oil sealed, single-/two-stage rotary vane pumps with air cooling and pressure oil lubrication and suitable for many coarse and fine vacuum applications. The pumps are equipped with a vacuum safety valve that vacuum seals the vacuum chamber and vents the pump at the same time when the pump is at a standstill. -

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 10: 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 11 Installation NOTE The transmission power of the pump’s magnetic coupling is so great that there is no overload protection for the motor. Three phase motor Inspection of the direction of rotation With pumps with three-phase motors is it necessary to check the direction of rota- tion! CAUTION Operating fluids may leak out!
- Page 12 Installation On site fuse protection with current circuit-breaker valid for motor version Depending on the process conditions and the intake pressure, the motor can be- without switch/with 3PTC come overloaded, i.e. the power input can exceed I . In cyclical operation, it is per- missible for the current to temporarily exceed the rated current I by 15%, provided that the motor temperature is monitored by means of a thermistor.

Page 13: 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 14: 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: Switching voltage: 5 ... -
Page 15: 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 16 Connect flushing gas at the hose nozzle of the gas ballast valve. 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. CAUTION Flushing gas pressure higher than allowed endangers the operational reliability of the pump.

Page 17: 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. -
