How to Determine Root Cause of Excessive Pump Vibration

Aug 22, 2018 · Long-term neglect of the pump case and/or motor cover studs of a BWCP can cause them to corrode and seize. New pump case studs have a zinc phosphate coating to improve corrosion resistance and paint adhesion with a high temperature antifriction coating. If the pump case or motor case gasket leaked or the plant is subjected to flooding, the studs can corrode and bind in place.
