Abstract
Systems and methods of monitoring a condition of a pump. One or more characteristics of a fluid flow of a fluid is monitored in a flow path of the pump to determine a fluid leakage flow rate. The fluid leakage flow rate is compared to a nominal flow rate for the pump. The pump efficiency for the pump is determined based on the comparison of the fluid leakage flow rate to the nominal flow rate. The pump efficiency is compared to a pump efficiency threshold and the condition of the pump determined based on the comparison.
