A power pump performance analysis system includes a signal processor connected to pressure sensors for sensing pressures in the cylinder chambers and inlet and discharge piping of a single or multi-cylinder pump. Pump speed and piston position are determined by a crankshaft position sensor. Pump vibration, fluid temperatures, and power input may also be measured by sensors connected to the processor. Performance analyses, including determination of pump volumetric efficiency, mechanical efficiency, suction and discharge valve sealing delay, valve and piston seal leakage, flow induced pressure variations, acceleration induced pressure detection, hydraulic resonance detection and pulsation dampener performance may be measured and selected parameters displayed on a visual display connected to the processor directly or via a network.
