Leybold Trivac D 40 B

Leybold Two-Stage Rotary Vane Vacuum Pump

We offer here a Leybold two-stage rotary vane vacuum pump. The TRIVAC B series are oil-sealed vacuum pumps operating on the rotary vane principle.

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

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

These are pinned to ensure easy disassembly and reassembly.
