Abstract
Techniques are provided for tuning a rotary positive displacement pump. The techniques include apparatus featuring a signal processor configured to the present invention may take the form of apparatus comprising a signal processor that may be configured to receive signaling containing information about actual pump performance data related to the operation of a rotary positive displacement pump; and determine corrected published pump performance data to operate the rotary positive displacement pump by compensating published pump performance data based at least partly on the actual pump performance data. The corrected published pump performance data may include a corrected published rated power, flow and slip factor, and the actual pump performance data contains information about actual power, specific gravity and viscosity related to the operation of the rotary positive displacement pump and received from a pump controller or controlling device, including a variable frequency drive.
