Major Repair Kit with Oil Pump Rotor, Leybold D 2.5 E (2 Series) Leybold Trivac D2.5E

The Leybold Trivac D2.5E is a small but powerful pump. It is a dual-stage, oil-sealed rotary vane pump . People use it in many places. Labs, leak detectors, small coating systems, and refrigeration work. It is also used as a backing pump for turbo molecular pumps and Roots pumps.

The D2.5E has a three-stage gas ballast device . This is important. It means the pump can handle water vapor very well. Stage 1 handles 10 mbar, Stage 2 handles 20 mbar, and Stage 3 handles 30 mbar. The pump is suitable for continuous operation at 1000 mbar.

The TRIVAC E pumps have an internal demister to keep the oil clean. They have a built-in oil pump for force-lubrication of the bearings .

But every pump gets tired. After thousands of hours, parts wear out. The pump takes longer to pull vacuum. It runs louder. The vacuum level just is not what it used to be.

You do not need to buy a new pump. You just need to rebuild this one.
