Leybold Two-Stage Rotary Vane Vacuum Pump Trivac D 40 B

Leybold

Type: Trivac D 40 B

The TRIVAC B 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 body is assembled from individual parts without sealing elements.
These are pinned to ensure easy disassembly and reassembly.
