Description
This specific part is the 2nd Stage Vane. Many larger vacuum pumps have two stages for better performance. The second stage handles the air from the first stage and creates an even stronger vacuum.
Over time, vanes wear down from friction. When they get too short, they can’t seal properly. This leads to a loss of vacuum power and makes the pump work less efficiently.
Replacing worn vanes with these Leybold parts restores that critical seal. It brings your pump’s performance back to its original specifications.
