Abstract
A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall and have a compliant edge configured to deflect or compress when presented with pinched material rather than jamming.
