A steel disc attached to the bottom of a grease pump. Like a follower plate, the inductor plate helps move product in a drum toward the inlet of the pump, and includes a seal that wipes the inside surface of the drum as the product level decreases. While a follower plate slides down the body of the pump, the inductor plate is fixed to the bottom end of the pump so that the weight of the pump helps push the inductor plate down onto the product, reducing cavitation by forcing the product towards the pump inlet.
