Plate, Spring, Duo 255M, Pfeiffer, DUO, Part# 380052

This spring plate is made for one specific pump model:

• Pfeiffer DUO 255M (Index C) 

The DUO 255M is a powerful two-stage rotary vane vacuum pump. It uses a magnetic coupling instead of a traditional shaft seal . This design means less maintenance and no oil leaks from the shaft area . It is built for tough industrial jobs.

The spring plate works with the spring to control movement inside the pump. It helps the valve system open and close at the right times. This keeps the pump running smoothly and efficiently.

When the spring plate wears out or gets damaged, the pump may not work as well. You might notice lower performance or strange noises. Replacing it with the right part brings your pump back to normal.
