Wilden has announced the release of its 76-mm (3”) size Full-Stroke Integral Piston Diaphragm (FSIPD). The new 76 mm (3”) FSIPD is ideal for use in Wilden’s Saniflo FDA pumps, as well as its Original, Advanced and Advanced FIT series of air-operated double-diaphragm (AODD) pumps.
Wilden 76 mm (3”) diaphragms are well suited for hygienic applications because they are constructed of food-grade Wil-Flex (Santoprene), and unlike conventional diaphragms, the integral piston is completely encapsulated within the TPE material, meaning there is no outer piston that can trap fluid and particles. The result is a durable, highly cleanable diaphragm assembly that features a large integral piston and a full-stroke shaft that enables it to maintain the same stroke length as conventional Wilden diaphragms. The diaphragm’s full-stroke design increases product displacement per stroke, which translates into improved suction lift, greater flow rates and higher efficiencies than experienced when using pumps that operate with reduced stroke diaphragms.
Features and benefits of the new Wilden 76 mm (3”) FSIPD model include:
• Full-stroke, FDA-compliant Wil-Flex, sanitary, integral-piston design
• No adhesive used in construction of FSIPD
• Elimination of outer piston abrasion – a leading cause of diaphragm failure
• Temperature range from -40°C to 107°C
(-40°F to 225°F)
• Meets the requirements of FDA CRF 21.177, EHEDG and 3A
The 76 mm (3”) model is the latest addition to Wilden’s FSIPD family, which also includes 25 mm (1”), 38 mm (1.5”) and 51 mm (2”) sizes. All four FSIPD sizes are ideal for general industrial applications where downtime and maintenance are more costly than replacement parts. For the 76 mm (3”) FSIPD, repair kit options are available that include two inner pistons, one shaft and two wedge-installation aids for convenience.
