1. A computer-implemented method of predicting a future maintenance event of a main pump associated with a wellbore pumping unit, wherein the wellbore pumping unit comprises a mixing system comprising a supply pump, the main pump, and a plurality of sensors, the method comprising:
retrieving, by a unit controller, a pump usage log associated with the main pump, wherein the unit controller comprises a processor, non-transitory memory, and an input-output device;
updating, by the unit controller, the pump usage log with one or more datasets of periodic pumping data indicative of a pumping operation;
predicting a future maintenance event via a predictive maintenance model, wherein the predictive maintenance model is configured to:
determine a probability of the future maintenance event for the main first pump in response to changes in the pump usage log when compared to a pump maintenance log; and
determine a pump life value comprising a percentage of pump usage before the future maintenance event;
determining the pump life value in comparison to a threshold value for i) a recommended maintenance period, ii) a required maintenance period, or combinations thereof; and
outputting, by the unit controller, indicia of the pump life value exceeding the threshold value via the input-output device, wherein the indicia is a visual cue, an audible cue, or both.
