Abstract: Apparatus includes a signal processor that receives signaling containing information about real time pump operating parameters related to pumps forming part of a pumping system in a plant/facility, and a user input selecting a pump for displaying the real time pump operating parameters on a control monitor to allow a plant/facility operator to implement a centralized pump control of the pumps at a given centralized location; and that determines corresponding signaling containing information to display on the control monitor the real time pump operating parameters to allow the plant/facility operator to implement the centralized control of the pumps at the given centralized location, based upon the signaling received.

Abstract: Apparatus is provided featuring a signal processor or processing module configured to receive signaling containing information about a pump no flow idle (NFI) state when the pump is running at a pump idle speed; and determine corresponding signaling containing information about whether the pump should remain in a no flow shutdown (NFSD) state or the pump NFI state, based upon the signaling received. The signal processor or processing module is configured to provide the corresponding signaling containing information about whether the pump should remain in the NFSD state or the NFI state.

Abstract: The present invention provides apparatus that features a signal processor or processing module configured to receive signaling containing information about an adaptive or self-calibrating set point control curve and a varying equivalent system characteristic curve based at least partly on an instant pump pressure and a flow rate using an adaptive moving average filter, and equivalent hydronic system characteristics associated with the instant pump pressure and the flow rate to corresponding motor power and speed reconstructed and remapped using a discrete numerical approach; and determine an adaptive pressure set point, based at least partly on the signaling received.
