Zusammenfassung:	A stuffing box assembly for an artificial lift system includes a stuffing box including a housing having a passage, in which the housing has a shoulder disposed along the passage. The stuffing box also includes a seal disposed within the passage and engaged with the shoulder. The seal is configured to engage a polish rod while the polish rod extends through the passage, and the seal is configured to expand radially in response to longitudinal compression of the seal. In addition, the stuffing box includes an actuator having an engagement element configured to move along a longitudinal axis to compress the seal. Furthermore, the stuffing box assembly includes a controller configured to determine a flow rate of fluid bypassing the seal based on one or more input signals, and the controller is configured to control the actuator based on the flow rate.
