Wilden® Receives Patent on Full-Stroke Integral Piston Diaphragms for AODD Pumps in Hygienic Market

Wilden®, the worldwide leader in air-operated double-diaphragm (AODD) pump technology, is proud to announce that its Full-Stroke Integral Piston Diaphragm (FSIPD) has received Patent No. 8,496,451 from the United States Patent and Trademark Office.

“This patent identifies Wilden as a global leader of AODD pumps in the hygienic industry,” says Robert Jack, Development Engineer, Wilden Pump and Engineering. “The FSIPD provides the clean-ability that customers need and adds the flow rate and suction-lift performance they want. In addition, customers will be happy to know that a Wilden FSIPD is about half the cost of a PTFE IPD.”

Constructed of Wil-Flex (Santoprene®), FSIPDs do not incorporate an outer metallic plate that requires the pump to be cleaned manually. Instead, the metallic plate is integrated into the material itself, resulting in a diaphragm design that uses the same shaft and inner piston as Wilden’s rubber and TPE diaphragms to maximize performance. Wil-Flex FSIPDs are easy to install and do not require inverting of the diaphragm for installation. Wilden FSIPDs do not use any adhesives that could get exposed to the pumping media. In addition, their material and construction make them a cost-effective alternative to PTFE IPDs.

Wilden’s full-stroke integral piston diaphragms are FDA-compliant and feature flow, suction lift and efficiency comparable to rubber and TPE diaphragms with clean-in-place (CIP) capabilities. They also meet FDA CFR 21.177, EHEDG and 3A requirements.

Wilden FSIPDs are available for use in 25 mm (1”), 38 mm (1-1/2”), 51 mm (2”) and 76 mm (3”) Hygienic™ Series pumps. These diaphragms can also be used in standard Wilden 25 mm (1”), 38 mm (1-1/2”) and 51 mm (2”) pumps, including the FDA-compliant Saniflo Series.
