Abstract: A monitoring system for a fluid pump having a fluid end and a power end is provided. The monitoring system includes an inlet pressure sensor attached to an inlet manifold of the fluid end. The inlet pressure sensor generates a signal indicative of an inlet pressure of a fluid being supplied to the fluid end. The monitoring system includes a discharge pressure sensor attached to the fluid end. The discharge pressure sensor generates a signal indicative of a discharge pressure of the fluid exiting the fluid end. The monitoring system includes at least one accelerometer attached to the fluid end. The accelerometer generates a signal indicative of vibrational data of the fluid pump. The monitoring system includes a controller which receives signals from the inlet pressure sensor, the discharge pressure sensor and the accelerometer and determines a possible failure mode of the fluid pump.
