Abstract: A pumping system featuring a pump, motor, a bearing assembly, integrated data acquisition system and combined programmable logic controller (PLC), data acquisition and modem. The pump couples to a pump shaft that responds to a pump shaft force to pump a liquid. The motor couples to the pump shaft, responds to VFD/VSD control signaling and provides the pump shaft force to drive the pump shaft. The bearing assembly includes a bearing with the pump shaft arranged therein and couples the pump and the motor. The variable frequency/speed drive (VFD/VSD) receives PLC control signaling and provides the VFD/VSD control signaling to drive the motor. The integrated data acquisition system responds to PLC data acquisition signaling, and provides integrated data acquisition system signaling containing information about an integrated set of pumping system parameters related to the pump, the bearing assembly, the motor and the VFD/VSD in the pump system. The combined programmable logic controller (PLC), data acquisition and modem provides the PLC data acquisition signaling and receive the integrated data acquisition signaling, provides PLC data acquisition modem signaling that exports performance data to the Internet to allow remote manual monitoring of the pump system, and provides the PLC control signaling to control the VFD/VSD and operate the pumping system as a controlled, closed loop system.
