One-Up Diaphragms
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.
