Pump diaphragms have a common flaw: the outer metallic plate requires the pump to be cleaned manually. Wilden now offers new food–grade diaphragms that already incorporate the plate within the component's flexible material. This patent pending innovation results in an all-new diaphragm design that features a large integral piston and longer rubber/TPE shaft, enabling it to maintain the same stroke length as traditional diaphragm designs. According to the manufacturer, the new 'full–stroke' design increased product displacement per stroke also leads to a higher suction lift..

“The introduction of Wilden’s Full Stroke Integral Piston Diaphragm is another powerful tool for liquid handlers searching for best-in-class suction lift and flow rates with unmatched clean-ability in their pumps. This product delivers exceptional product-handling versatility,” said Greg Duncan, Wilden’s Director of Engineering. “We have already heard back from the field that this combination of pump performance and enhanced clean-ability are offering operators just what they need.”
