Ultra-Flex® technology incorporates many revolutionary design concepts, which reduce internal stress.
Wilden’s Ultra-Flex® diaphragm is molded in an "operational shape" such that stress concentration is minimized throughout its entire stroke length. The transition radii are tailored to minimize stress throughout the dynamic area of the flex path.
Ultra-Flex® hardware (shaft, pistons, and spacers) maximizes the amount of diaphragm material involved in the diaphragm’s movement. This improvement decreases the unit loading on the diaphragm and alleviates stress concentrations.
Controlled fabric placement decreases tensile loading to further reduce stress.

LONGER LIFE GUARANTEE:
All Ultra-Flex® diaphragms are guaranteed to deliver longer life than your existing Wilden diaphragms. If less flex life is realized, Wilden will send you a new set of Ultra-Flex® diaphragms free of charge. This comparison must be conducted in the same pump, utilizing the same diaphragm material on the same application. Failures due to misapplication, as well as consequential damage to other pump components and/or associated equipment are not covered by this guarantee.
Note: The conversion to Ultra-Flex diaphragm system will require the combined use of UF diaphragms, UF shaft and UF outer pistons. Your pump's maximum flow rate will be reduced by about 7% - air consumption will increase up to 12% when compared to other Wilden systems. The usage of Ultra-Flex diaphragms goal is to increase the life of diaphragms in severe duty applications.
