  • Centerline supported pump? - Pump engineering -

    2011-5-23 · Centerline supported simply means that the pump casing is supported at the rotating assembly centerline as opposed to being supported at a point somewhere lower on the case. In API type services where elevated temperatures are routine, this allows thermal expansion growth of the case (or barrel here) to be symmetric from the shaft centerline outwards.
