  • Page 9: Function

    Product description Function The vacuum pump UNO 30 M is a single stage rotary vane pump and is used primarily for rough and medium vacuum applications. The pump is fitted with a hydraulically con- trolled 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 Installation Setting up the pump Installation location Observe the following requirements when setting up the pump: ● Consider the load-bearing capacity of the installation site. ● Maximum installation altitude 2000 m (above mean sea level) ● Permissible ambient temperature: +15 ... 40°C ●...

  • 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 14 Installation Inspection of the direction of rotation For pumps with three-phase motors, it is necessary to check the direction of rotation! CAUTION Operating fluids may leak out! If the direction of rotation is incorrect, there is a danger that operating fluids may leak at the vacuum flange.

  • Page 15: 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 16: 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 17: 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 18: 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.

    Operation 45.1 Fig. 12: Gas ballast valve with flushing gas connection  Unscrew purge orifice 45 from gas ballast valve 42 and insert elsewhere in the flush- ing gas supply line for flow limitation.  Replace purge orifice 45 with an elbow union 45.1. ...

  • Page 20: 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 21: 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.
