1. A performance analysis system for analyzing selected performance parameters of a pump system including a reciprocating piston power pump having at least one reciprocating piston operable to displace fluid from a housing having a pumping chamber, said analysis system comprising:

  • a piston displacement position sensor operable to sense movement of said piston for determining a position of said piston;

    a pressure sensor operable to sense pressure in said chamber;

    a signal processor operably connected to said sensors for receiving signals therefrom and for generating information corresponding to at least one performance parameter selected from a group consisting of delay in opening or closing of one or more valves for admitting fluid to and discharging fluid from said chamber, pressure variation indicative of a leakage condition of a piston seal, maximum and minimum chamber pressure, pump volumetric efficiency and pump fluid flow rate; and

    means for displaying said at least one performance parameter.
