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 series are oil-sealed vacuum pumps based on the rotary vane principle.

The oil injected into the pumping chamber serves for sealing, lubrication, and cooling.

The pump housing is composed of individual parts without sealing elements.

These are pinned together to ensure easy disassembly and reassembly.
