GUARANTEED TO LAST LONGER
FOR AIR-OPERATED
DIAPHRAGM PUMPS

GORE™ ONE-UP® Pump Diaphragms are durable and versatile. With proprietary PTFE on the wetted side, they last significantly longer than other conventional PTFE diaphragms. These diaphragms provide a dramatic improvement in service life and are considerably stronger, with greater flex life. Excellent chemical resistance makes ONE-UP® Pump Diaphragms extremely versatile. They are suitable for use with most chemicals and in elevated temperatures and pressures, and are ideally suited for general-service pumps that are used for a variety of pumping tasks.
