System and method for testing a pump. The testing of the pump includes determining a Mechanical Power Index (MPI) for the pump. The MPI is determined by operating the pump at operating speed for a minimum operating interval. When the pump is stopped under normal operation by the application, the pump speed is continuously monitored. The time when the pump speed decreases to an initial speed close to the operating speed is read as an initial time. When the pump speed decreases to a final pump speed close to the critical speed, the end time is read and the elapsed time is determined as &#x394;t=end time&#x2212;initial time. The MPI is calculated to be the initial pump speed minus the final pump speed divided by &#x394;t. The MPI can be used during the lifetime of the pump to determine when the pump is deteriorating.
