I work on an offshore oil production platform. Recently, we experienced a problem where an oil-to-shore pump (a centrifugal pump) was not moving liquid out through the discharge and pressure of the pump was higher than usual. What makes the situation more perplexing is that all the valves were lined up properly on the pump. Any explanations for this will be greatly appreciated.
Have an insight or suggestion?

Re: Malfunctioning pump discharge valve25 September 2007 at 1:29pmOne reason a centrifugal pump will not move liquid out through its discharge, is if a valve on the discharge line somewhere, has been throttled back or shut down. Another reason is that there is a blockage somewhere in the discharge line that it stopping the flow.
