Leybold Trivac D2.5E 140000 Dual Stage Rotary Vane Vacuum Pump 230V 2.5 m³/h

Leybold Trivac D2.5E 140000 Dual Stage Rotary Vane Vacuum Pump 230V 2.5 m³/h

The Leybold Trivac D2.5E is a compact, oil-sealed dual stage rotary vane vacuum pump designed for general-purpose rough and medium vacuum applications. Manufactured by Oerlikon Leybold Vacuum in Germany, the Trivac D2.5E achieves an ultimate pressure of ≤ 0.02 mbar with a pumping speed of 2.5 m³/h, making it well suited for laboratory and light industrial use. The unit is driven by a single-phase Hanning Elektro-Werke motor and is configured for 220–240V/50 Hz or 230V/60 Hz operation.

Applications

The Leybold Trivac series is one of the most widely used families of rotary vane vacuum pumps in laboratory and industrial settings. The D2.5E is a small-displacement model commonly used as a backing pump or standalone roughing pump in applications such as vacuum filtration, freeze drying, thin-film deposition (backing for turbomolecular or diffusion pumps), mass spectrometry sample handling, and general laboratory vacuum work. Leybold Trivac pumps are a standard choice in university labs, pharmaceutical research, semiconductor process equipment, and analytical instrument support — valued for their oil-sealed two-stage design, which allows them to reach medium vacuum levels (into the 10⁻² mbar range) that single-stage pumps cannot achieve. The gas ballast valve allows operation with condensable vapors without oil contamination. As a German-engineered pump from Oerlikon Leybold Vacuum, the Trivac D2.5E represents a well-established and widely supported platform with a long history in both research and production environments.
