Description
Leybold Trivac pump, vanes spin inside a chamber to create suction. These vanes need to push against the chamber wall just right.
That’s where this spring comes in.
It sits behind the pump’s vanes, providing a gentle, constant push. This push keeps the vanes in proper contact with the wall as they spin. Without the right tension from this spring, the vanes can’t seal properly. Replacing worn springs is key to pump maintenance. This isn’t just any spring. It’s the original part made for your specific Leybold Trivac model
