Wilden announced that it has recently upgraded the design of its cost-effective Wil-Flex Diaphragms 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 (ethylene propylene diene Monomer) rubber and polypropylene, Wil-Flex diaphragms are an excellent low-cost alternative to PTFE diaphragms. Their design characteristics make them ideal for use in Paint & 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.
Wil-Flex diaphragms are currently available for use on the Advanced Series Metal 25mm (1”) bolted stainless steel and aluminum, 38mm 1-1/2”) bolted stainless steel, and 76mm (3”) bolted stainless steel and aluminum models. Wilden’s Advanced bolted pumps also include the Pro-Flo X air distribution system that allows the pump user to control the flow rate and maximize efficiency to reduce processing costs.
