Who has encountered the problem of a broken vacuum pump piston? There are cracks in the piston of my vacuum pump, and a piece of metal has fallen off. What causes this?

The piston breaking you mentioned is quite rare, unless there are serious manufacturing defects; in contrast, piston rod breaks do occur from time to time

Of course, you should carefully examine the fracture surface to determine whether it shows signs of an old fracture or a new one, and so on
