  • Symptoms and Causes of Hydraulic Pump Failure

    2014-2-18 · The contaminated hydraulic fluid makes strange knocking or banging noise when compressed or decompressed, when moving through the hydraulic pump. The degradation of the hydraulic fluid is greatly accelerated by the aeration. Aeration can damage various hydraulic pump parts because the seals are over heated. Air usually enters into the pump through the inlet. Therefore, it is …
