    Abstract: A prime mover includes a shaft assembly that is supported for reciprocal movement between first and second ends of a stroke, and that includes first and second portions having a first material, and a third portion in between the first and second portions, having a second material, different from the first material. A single inductive proximity sensor makes a first indication when proximate the first material, and makes a second indication, when proximate the second material. A portion of the sensor is proximate the first portion when the shaft is at the first end of the stroke, the same portion of the same sensor is proximate the second portion when the shaft is at the second end of the stroke, and the same portion of the same sensor is proximate the third portion the entire time the shaft is in between the first and second ends of the stroke.

    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.

    Abstract: Embodiments of the present, invention provide a system and method for reducing the hold-up volume of a pump. More particularly, embodiments of the present invention provide a system and method for determining a home position to reduce hold-up volume at a dispense pump and/or a feed pump. The home position for the diaphragm can be selected such that the volume of the chamber at the dispense pump and/or feed pump contains sufficient fluid to perform the various steps of a dispense cycle while minimizing the hold-up volume. Additionally, the home position of the diaphragm can be selected to optimize the effective range of positive displacement.
