Abstract
A seal assembly is provided that can be automatically cleaned in place, without requiring manual cleaning by a technician, and that can be used with food processing equipment. The seal assembly has a back plate that is attached to a wall of the food processing equipment and a seal cover that connects to the back plate. A cavity is defined between the seal cover and a rotating shaft that extends into the seal assembly, and a cleaning fluid may be introduced into the cavity. The cavity may house a pair of seals that are longitudinally spaced from each other and a hub collar between the seals and which may influence a fluid flow path of the cleaning fluid through the cavity.
