It’s a fact of life: the components on an AODD pump – diaphragms, balls, valves, seats, gaskets, O-rings – will eventually wear out. So, when they need to be replaced, it should be a simple, easy fix for the operator. Too many times, though, a manufacturer’s repair kits don’t satisfy that simple need, meaning they feature too many parts that require too many different tools, resulting in a frustrating, time-consuming repair process.
