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.
Satisfaction Guaranteed
We guarantee your satisfaction. If, on your initial order, you are not completely satisfied with the performance-in-use of the diaphragms, return them to us for a full refund of the purchase price.
