1. A system comprising:
- a plurality of sensors each disposed in or proximate to a reciprocating system, wherein each sensor is positioned to monitor at least one parameter related to the reciprocating system'"'"'s performance over time and to periodically measure values of the corresponding at least one parameter, each of the sensors measuring values of at least one of a plurality of parameters differing from a value measured by any other one of the sensors; and
a data processing system configured toperiodically receive values for the parameters based upon measurements from the plurality of sensors,combine received values based upon measurements during a single measurement interval by different ones of the plurality of sensors;
aggregate the combined values over a plurality of measurement intervals to compute a total energy number for at least one part of the reciprocating system; and
compare a current computed value of the total energy number with a predictive failure value specific to a configuration for the reciprocating system.

Abstract
Performance parameters for a reciprocating pump including pulsation energy, temperature energy, solids, Miller number and chemical energy and the like are monitored and employed to at least periodically compute a total energy number over the operating life of the pump. The current computed value is compared to a predictive failure value empirically determined for the respective pump design, to determine when failure is likely to be imminent. Scheduling of maintenance with other pumping operations and objective rating of competing designs is possible based on the total energy number.
