The Wilden clamped metal Air-Operated Double-Diaphragm (AODD) pumps have a clamped configuration that ensure reliability without sacrificing ease of maintenance. The clamp bands come off quickly and easily for replacement of diaphragms and cleaning. These pumps offer increased productivity. Wilden's metal pumps are perfect for a number of applications. Wilden also offers a multitude of elastomer options, including Teflon® PTFE, to meet abrasion, temperature and chemical-compatibility requirements.
