Keeping your stuffing box adequately maintained while monitoring your seal integ – rity and confirming rod rotation is crucial. The mAutoGrease+ compensates for the normal loss of grease using predetermined set points, automatically triggering the mAutoGrease+ pump. The system will report if the grease pressure drops to zero a set number of times indicating action is required on either tightening the gland nut or replacing the seals. The rod rotator sensor package is a bolt-on system that monitors the rotation of your rod rotator to ensure proper operation is taking place.
