Claim:
1. A system for detecting leakage in a pump, the system comprising: a first pressure sensor located in a suction manifold of the pump and configured to output a suction manifold pressure signal indicative of a pressure of the suction manifold; a second pressure sensor located in a discharge manifold of the pump and configured to output a discharge manifold pressure signal indicative of a pressure of the discharge manifold; a plurality of third pressure sensors, wherein at least one third pressure sensor is located in each cylinder of the pump such that each of the third pressure sensors are configured to output a cylinder pressure signal indicative of a pressure of one of the cylinders of the pump; and a controller disposed in communication with the first pressure sensor, the second pressure sensor, and the third pressure sensors; the controller including a memory with a plurality of pressure verses time curve sets including a suction manifold pressure curve, a discharge manifold pressure curve, and at least one cylinder pressure curve, each pressure verses time curve set having an associate location of a leak in the pump and amplitude of a leak in the pump; the controller configured to:
