Abstract: A pump system features a power adapter and a pump having a signal processor. The power adapter includes voltage settings that respond to a voltage setting by a user and provide a selected voltage. The signal processor receives signaling containing information about the selected voltage supplied to a motor to run the pump, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received.

Abstract: A fluid delivery system for delivering a metered dose of fluid from a supply tank (28) to a downstream chamber or vessel (10), comprises a pump apparatus (20) comprising a pump plunger (32) which is operable to perform a pumping stroke under the control of an electromagnetic actuator (36), including a solenoid (36a), to effect delivery of the fluid and a control unit (24) for supplying an input signal (58) to the solenoid (36a) to initiate a current flow to the solenoid (36a) and thereby initiate movement of the pump plunger (32). An electronic device (54) provides an output signal to indicate that movement of the pump plunger has stopped at the end of the pumping stroke, and a timer determines a time difference between the input signal (58) being supplied to the solenoid (36a) and the output signal being output by the electronic device (54). A processor (26) compares the time difference with a predetermined time difference and determines, as a result of the comparison, whether or not the pump plunger (32) has performed a valid pumping stroke in which an intended volume of fluid is displaced.

Abstract: The device for counting the strokes of a piston sliding within a cylinder comprises a support housing a magnet which generates a magnetic field. The support also houses a sensor arranged to sense the magnetic field, such that the passage of the piston into a position corresponding with the magnet causes a disturbance in the magnetic field, which is sensed by the sensor, to indicate a stroke of the piston.

Abstract: Pump maintenance data associated with each of plural components of each of plural frac pumps of each of plural frac pump transports of a frac fleet is accessed. The pump maintenance data includes usage data of plural well completion operations performed by the frac fleet. The usage data indicates actual component life intervals of each of the plural components and corresponding operating conditions. The pump maintenance data is analyzed to generate a maintenance prediction model that is configured to output for each of the plural components, a predicted component life interval as a function of an operating condition. A current operating condition corresponding to a current well completion operation of the frac fleet is accessed. The maintenance prediction model is applied to generate the predicted component life intervals for each of the plurality of components of the frac fleet based on the current operating condition.

Abstract: An adhesive dispensing system includes a pump and at least one sensor positioned to sense movements of a component of the pump and produce signals based on the sensed movements. The dispensing system also includes a controller operating the pump and communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals. As a result, one or more diagnostic processes are enabled at the controller during operation of the adhesive dispensing system. These diagnostic processes may include a leak rate test for the dispensing system, an overspeed detection test for the pump, and expected life cycle monitoring of the pump or other components.
