Chesterton 1765 is ideally suited for bleach pumps and other rotary applications requiring a white, non-staining packing. Constructed from chemically resistant, expanded PTFE material, this packing demonstrates higher speed performance capabilities than traditional PTFE materials for improved performance in a wide range of applications. Chesterton 1765 is ideal for rotary applications where chemical resistance is required and process needs to remain non-contaminated, such as ClO2 pumps, paper stock, and feeders.
