The Leybold TRIVAC D 2.5 E Two-Stage Vacuum Pump, G S WM (140009) is an oil-sealed rotary vane pump for generating rough and medium vacuum or operating as a backing pump in vacuum systems. It provides pumping speeds of 2.7 m³/h at 50 Hz and 3.3 m³/h at 60 Hz, with an ultimate total pressure of 2 × 10-3 mbar without gas ballast.
Key Features
- Two-stage oil-sealed rotary vane design, developed for rough and medium-vacuum applications
- Frequency-dependent pumping performance, delivering 2.7 m³/h at 50 Hz and 3.3 m³/h at 60 Hz
- Low ultimate total pressure, reaching 2 × 10-3 mbar without gas ballast
- Gas-ballast operation for condensable vapours, with a maximum water-vapour tolerance of 30 mbar
- Protection against oil backstreaming, using oil-pressure-controlled safety valves when the pump stops
- DN 16 ISO-KF vacuum connections, provided on both the intake and exhaust sides
- Wide single-phase power compatibility, supporting 100–120 V or 200–240 V at 50/60 Hz
- Air-cooled integrated motor design, supporting compact installation without an external cooling circuit
- Low operating noise, rated at 47 dB(A)
- IP54-rated construction, providing protection suited to routine laboratory and industrial operation
- LEYBONOL LVO 130 operating oil, with a specified fill range of 0.4 to 0.7 L
- Compact pump dimensions, measuring approximately 424 × 127 × 250 mm
Note: Pump oil is supplied separately and must be added before the pump is operated.
Benefits
- Supports stable vacuum generation for laboratory, research and industrial processes.
- Provides effective pumping from atmospheric pressure into the medium-vacuum range.
- Helps protect connected vacuum systems against inadvertent venting and oil migration during shutdown.
- Allows condensable vapours to be handled within the specified gas-ballast and water-vapour limits.
- Reduces workplace noise and vibration through the compact TRIVAC E pump design.
- Simplifies integration through standard DN 16 ISO-KF connections and a dual-voltage single-phase motor.
