Pfeiffer Duo 2.5A Vacuum Pump PKD41 018A – For Parts Used (Out of Stock)

Untested for parts or repair.

We were unable to power as we did not understand the wiring, there is ten wires. We do not know the history of the pump but we pulled the fan cover off to turn by hand and found the plastic fan had a little damage and was making contact on one side for a half turn each revolution. The cover also had a cracked corner.

We are selling AS-IS, no returns due to lack of testing and the noted observations about the fan and cover.
