A chemical processing plant had been experiencing high vibration and bearing failures on their furnace water circulation pumps. This application uses a sealless combined pump and motor, due to the high pressure and high temperature water being circulated. This vibration and wear required that the motors be overhauled approximately once per year at a cost in excess of $100,000. These issues had been occurring since the pumps were first installed in the late 1990s.
