ABSTRACT:
A dual chamber pump assembly comprises two separate bellows pumps driven from a single motor. The belows pumps can be operated independently, or simultanously, by selectively engaging clutches coupled to the motor and the pumps. A replenishment system for a film processor incorporating such a pump assembly has a plurality of tanks for solutions used in processing film, and each of the pumps is connected to one of the tanks and to a source of replenishment solution for its respective tank. By selectively engaging the clutches for the bellows pumps, the tanks can be replenished independently or simultaneously, as needed.
