The integrated wireless data system and method may be configured to allow for bi-directional communication with a central station to enable human intervention with pumpjack and to store pump parameters in a database for use in development of predictive maintenance techniques.

A dual pump smart control system. The operating time and the number of simultaneous operations are analyzed and compared with a reference time and a reference number, so that a controller determines whether or not the operation is normal. Afterwards, the driving of a first pump and the driving of a second pump are differentially controlled depending on whether or not the operation is determined to be normal by the controller. Thus, a malfunction caused by the concentration of load at a specific pump is prevented. Accordingly, the dual pump smart control system precisely controls the driving of the dual pumps and enables the pumps to operate efficiently.

Operating an engine exhaust aftertreatment system includes receiving fluid pressure data of a reductant pump, determining a pump operating state, and comparing a pump health parameter to a prognostic pump failure criterion based upon the determining a pump operating state. Operating an engine exhaust aftertreatment system further includes outputting a pump health alert based upon a difference between the pump health parameter and the prognostic pump failure criterion. Related control logic is also disclosed.

A test controller and method to operate a rotary motor of a pump are provided. The test controller includes a test speed circuit electrically coupled to, but detachable from, the pump and being configured to apply at least one signal to the pump motor to cause the pump motor to rotate at a predetermined test speed and/or for a predetermined test time. An actuator selectively activates the test speed circuit to operate the pump motor at the predetermined test speed and/or for the predetermined test time. The method includes electrically coupling the test controller to the pump and, in response to selective activation of the actuator, selectively activating the test speed circuit to apply at least one signal to the pump motor to operate the pump motor at a predetermined test speed and/or for a predetermined test time. The method further includes detaching the test controller from the pump.
