Wilden”s Wil-Flex diaphragms for air-operated, double-diaphragm pumps are designed for easy installation. The 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, the diaphragms offer a 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 easily handle abrasion, and wide swing in pH levels. Because of their thermoplastic qualities, the diaphragms have inherent tensile strength and do not need fabric reinforcement. The diaphragms are currently available for use on the Advanced Series Metal 25mm (1”) bolted stainless steel and aluminum, 38mm (1.5”) 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 flowrate and maximize efficiency to reduce processing costs.
