Mobile vacuum pump units

For evacuation of air or nitrogen

B046R13
Mobile vacuum pump unit with solenoid valve

The mobile vacuum pump unit is convincing by its easy handling. The unit serves for evacuation of air or nitrogen from switchgear. The 40 m³/h vacuum pump (standard version) enables a fi nal vacuum of < 1 mbar. Thus it is guaranteed that no air/gas mixture can be generated and the excellent insulation properties of SF6 are maintained. The 2-stage vacuum pump (available as option) even reaches a fi nal vacuum of 0.0067 mbar.

The B046R13 version is equipped with a solenoid valve instead of a ball valve. Therefore, operating errors are avoided since the valve is closed automatically in case of function end or interruption of circuit.

Both versions are available in different performance classes (see optional equipment), so that all requirements can be easily met.

  • Steerable and fixing rollers allow comfortable transportation
  • Use of self-closing couplings DN20
  • Different performances are available (see options)
  • Adapters for other nominal widths are available
  • Protection of the vacuum pump against overpressure by a solenoid valve (B046R13)
  • Digital vacuum indication in mbar
  • With practical storage tray for accessories

B046R20

This vacuum pump unit is "powerful" - its nominal suction capacity is 200 m³/h at 50 Hz for quick and reliable evacuation of air to a final vacuum of 1 mbar. This unit is particularly suitable for the evacuation of large gas compartments.

Two coupling connections (DN20 and DN40) allow the evacuation of two gas compartments at the same time without any manifold that means more efficiency and higher productivity during operation.

Other features:

  • Steerable and fixing rollers allow comfortable transportation
  • Use of self-closing couplings DN20 and DN40
  • Protection of the vacuum pump against overpressure by a solenoid valve
  • Different hose lengths are available as option
  • Digital vacuum indication in mbar
  • Tool box for hoses and accessories

Z300R11
Nominal suction capacity 165 m/³ vacuum pump
Nominal suction capacity 250 m³/h Roots pump

Z300R12
Nominal suction capacity 205 m/³ vacuum pump
Nominal suction capacity 495 m³/h Roots pump

This series is very powerful and allows quick evacuation of large gas compartments. A vacuum pump combined with a Roots pump enables to obtain a final vacuum of 2x 10-2 mbar. Thus not only air but also moisture is removed from the circuit breakers. Therefore the subsequent filling process is prepared perfectly.

Three coupling connections (DN20 and 2x DN40) allow the evacuation of two gas compartments at the same time without any manifold that means more efficiency and higher productivity during operation.

Other features:

  • Steerable and fixing rollers allow comfortable transportation
  • Tool box for hoses and accessories
  • Self-closing couplings
  • Protection of the vacuum pump against overpressure by a solenoid valve
  • Different hose lengths are available as option
  • Digital vacuum indication in mbar
