The design of the company’s cost-effective Wil-Flex™ Diaphragms has been upgraded to allow for easy installation. The Wil-Flex diaphragms are now available in a flat profile design, eliminating the need to invert the diaphragm when rebuilding a pump. Made of Santoprene®, which is a thermoplastic elastomer that links EPDM rubber and polypropylene, Wil-Flex diaphragms are an ideal low-cost alternative to PTFE diaphragms. Their design characteristics make them ideal for use in paint and coatings applications due to long flex life, ability to easy handle abrasion and wide swing in pH levels. Because of their thermoplastic qualities, Wil-Flex diaphragms have inherent tensile strength and do not need fabric reinforcement.
