As the parts that are constantly in motion during an AODD pump’s operation – with any breakdowns or failures resulting in undeniably costly and oftentimes hazardous product leaks – careful consideration must be taken in regard to diaphragm selection.
That’s why Wilden® has engineered its Chem-Fuse Integral Piston Diaphragms (IPDs) to deliver an elevated level of pumping performance, reliability, safety, and cost effectiveness. Most significantly, Wilden Chem-Fuse Diaphragms eliminate a potential leak point at the outer piston, making Chem-Fuse diaphragms the best choice when the application involves the transfer of critical, dangerous, or hazardous liquids. Designed to last up to 3x longer than a conventional diaphragm, Chem-Fuse Diaphragms do not compromise your pump’s performance, increasing flow and suction lift by 100% compared to PTFE laminate diaphragms. Additional benefits include faster installation and easy cleanability for changeovers between products.

Jim Wilden revolutionized the pumping industry when he invented the air-operated double-diaphragm (AODD) pump in 1955. Since that time, Wilden® Pump and Engineering Company has been at the forefront of bringing AODD technology into the future by building its extensive infrastructure, knowledge base and intellectual capital. Wilden offers a comprehensive ...
