Abstract
Techniques are provided for tuning a twin screw positive displacement pump having a signal processor with a signal processor to receive signaling containing information about actual pump performance data for actual rated conditions captured during a tuning function related to the operation of a twin screw positive displacement pump; and determine corrected pump performance data to operate the rotary positive displacement pump by compensating pump performance data being used for operating the twin screw positive displacement pump based at least partly on the actual pump performance data for the actual rated conditions captured during the tuning function. The corrected pump performance data includes corrected published pump performance data having a corrected published rated power and slip factor, and the actual pump performance data contains information about actual power, specific gravity and viscosity related to the operation of the twin screw positive displacement pump and received from a pump controller or controlling device, including a variable frequency drive.
