    Backs of pump grinding against fans

    I have two ebara centrifuge pumps and the back plate of each keeps grinding against the rear fans. We have had to take the plates off to compensate but clearly this is a bad idea longer term. Does anyone know a good workaround?

    Obviously there has been some damage to the covers if this is a new phenomenon. I would just try to fix the damage. The fans don't work without that shroud.

    New covers that aren't dented to hell or new pumps. Buy decent mechanical equipment and take care of it.
