Hydraulic Pump Case Drain Test at sylviarfowlero blog

Hydraulic Pump Case Drain Test.this means that the condition of a pump or motor can be determined by measuring the flow from its case drain line (internal leakage) and expressing it as a percentage of its theoretical or design flow. Not all internal leakage from pumps and motors is evident as case drain flow;

Keep in mind that there will always be some level of internal leakage expected. The case drain should experience minimal flow and low pressure. interpretation of the subscripts is “leak path from pressurized port a to case drain port” and “leak path from pressurized port b to case drain port,” respectively.
