  • Redundant, dedicated variable speed drive system
    Patent number: 6257833
    Abstract: A redundant, modular pump system includes a plurality of substantially identical pump modules. Each module includes constant speed drive circuitry, variable speed drive circuitry and a pump. Expansion is accomplished by adding modules. Reliability is enhanced by being able to operate each pump at constant or variable speed irrespective of whether other modules are being operated at different variable or constant speeds. A common, software driven control element activates drives and other devices in the modules to provide fluid on demand at a pre-selected pressure.
