During an AODD wet-end rebuild, center disk orientation and material matter. Installing a non-beveled face against the diaphragm—or reversing air-side and wetted-side disks—can accelerate abrasion, corrosion and premature diaphragm failure.

AODD pumps can tolerate dry running, but that doesn’t mean it should become normal operating practice. This article explains how dry running can accelerate component wear, increase compressed-air consumption, and raise maintenance costs—and outlines practical ways to prevent it using dry-run protection devices, liquid level controls, and pump controllers.

Pilot Valve Troubleshooting: Why Your Yamada NDP Pump Is Cycling Unevenly

Learn common AODD pump failure causes, diaphragm and check-valve issues, preventive maintenance tips, and proper reassembly practices to reduce downtime.

Water hammer is one of the more common—and costly—issues encountered in industrial pumping systems. In simple terms, water hammer is a sudden pressure surge within a piping system caused by a rapid change in fluid velocity.
