Bearing Failure and OverHeat

  1. Nov 18, 2009 #1
    Dear all,

    I'd like to ask what are the causes for a roller bearing in a vertical pump to overheat and burn as we have got this incident in our plant and am trying to find out what can cause such a thing.
    Pump details:
    1. Sulzer Waste Water Pump (Model No.: VCM 4X10A
    2. Pump has been overhauled and kept as stand by in Maintenance Work Shop.
    3. Bearing lubrication is from the housing it self (No lubrication system)

    What kind of pump is it?

    General causes for bearing failure can be attributed to misalignment, operating the pump at a distance from its BEP, poor lubrication, pipe loads, etc...

    Is it a sealed bearing or one that requires greasing?
