ABSTRACT:
A processor is provided for processing film, paper and other sensitized materials. The processor includes a chemical containing tank in which the processing takes place and a circulation pump which is removably clipped to a sidewall of the tank. The pump has a head which is submerged in the chemical but the pump motor is positioned above the chemical level. A hollow, cylindrical filter element is mounted on the pump intake and baffles are provided on the ends of the filter to direct fluid through the filter prior to entering the pump intake. An oscillating replenishing pump is also removably mounted on the tank for adding fresh chemicals to those in the tank and facilitating mixing thereof. A heater is provided either within the filter element or beneath the tank to maintain the desired chemical temperature. A minimum of tubing is required to circulate the chemicals for conditioning, thereby reducing the cost and size of the processor while allowing for ready drainage and replacement of the chemicals.
