  • Top 10 Questions About Air Operated Diaphragm

    Deadheading means you shut off the pump’s ability to discharge fluid by closing a valve. The fluid will churn inside the pump until it heats into a vapor. Once a vapor, any bushings or mechanical seals in the pump can heat to the point that they can either crack, shatter, score, compromise elastomers…and ultimately kill the pump.
