Leybold Trivac D 40 B

Leybold Two-Stage Rotary Vane Vacuum Pump

Here we offer a Leybold two-stage rotary vane vacuum pump.
The TRIVAC B are oil-sealed vacuum pumps based on the rotary vane principle.

The oil injected into the pump chamber serves as a sealant, lubricant, and coolant.

The pump body is assembled from individual components without sealing elements.

These parts are doweled together to allow easy disassembly and reassembly.

Ultimate pressure: 2 x 10⁻³ mbar
Motor: 3-phase, 230/400 V, 50/60 Hz
Pumping speed (50 Hz): 40 m³/h
Djdpfeq Su D Nex Ad Uocd

Environmentally Friendly:
• Quiet operation
• Vibration-free running
• Energy-saving

Energy Effiicient:
• Low power consumption
• Minimal heat emission

Modern Vacuum Technology:
• High pumping speed down to ultimate pressure
• Low ultimate pressure, even with gas ballast
• High water vapor tolerance
• Suitable for continuous operation up to 1000 mbar
• Integrated oil pump, force-lubricated slide bearings
• Minimal air intake
• High leak-tightness (suitable for 4He)
