Pump Diaphragms


Ultraflex is a VERSIV™ Multimaterial Composite with all the benefits of regular PTFE skived films and enhanced flex resistance, especially for high-pressure requirements.


Used in the most demanding high-pressure applications, flex barrier Ultraflex VERSIV Multimaterial Composite is an unmatched PTFE solution for the highest flex life requirements and permeation resistance. A bondable version with best-in-class etching on one or both sides adds another dimension to the range.

Product Details

Ultraflex VERSIV Multimaterial Composite has the highest flex life compared to regular PTFE (up to 200% higher) and its high flex resistance means it has a long MTBF (mean time between failure). Its unique PTFE fabric is particularly suitable for high-pressure requirements, delivering performance levels no other material can offer. A smooth surface means there are no contamination anchor points and it offers the lowest permeation rate of flex barriers – enabling robust protection of outer layers and equipment from aggressive chemical media. It demonstrates an extreme reduction in deformation under load thanks to higher modulus and clearly reduced cold flow behavior, while high-quality resins produce high quality with no staining. Safe to use in food and pharma applications, Ultraflex provides continuous service temperatures over an impressive range, from cryogenic up to 500°F (260°C)
