Pumps with closed-style impellers will include a casing wear ring and possibly an impeller wear ring that is fitted to the outside diameter (OD) of the impeller suction eye, both of which are suction side wear rings. If the noise becomes overly loud or obnoxious, this could be an indication of a problem and you should call a professional. Common noise indications of a bad water pump can include a loud grinding noise that may be caused by worn-out bearing or worn impeller, a squealing noise caused by a dry seal, or a clunking or knocking noise that could be caused by a faulty drive belt or other mechanical issues.
