Field Testing

GORE™ ONE-UP® pump diaphragms have been extensively field tested in a wide variety of industries including chemical processing, pharmaceuticals, paint, solvent and detergent manufacturing, and wastewater treatment. Documented case histories show that the average service life is 3.5 times longer than conventional PTFE diaphragms.

Long Service Life

The superiority of the PTFE technology developed by Gore ensures that pump diaphragms will provide extended service life.

Easy Installation

Since the GORE™ ONE-UP® pump diaphragm is a one-piece design, it is simple to install. Whether it incorporates bolt holes or a perimeter sealing bead, it fits easily into the pump housing without the difficulties associated with installing two-piece diaphragm sets.
