1. A system for monitoring a pump, comprising:

  • a first stage pump;

    a second stage pump in fluid communication with and downstream of the first stage pump;

    a pressure sensor to measure the pressure of a fluid; and

    a pump controller to control fluid pressure at the second stage pump by adjusting the operation of the first pump, the pump controller coupled to the first stage pump;

    second stage pump and pressure sensor, the pump controller operable to;

    create a first operating profile corresponding to a parameter; and

    compare each of one or more values associated with the first operating profile with a corresponding value associated with a baseline profile to determine if each of the one or more values is within a tolerance of the corresponding value.
