Yamada K45-AM Air Motor Reseal Kit For NDP Series Pumps

The Yamada K45-AM is an air motor reseal kit for Yamada NDP-40 and NDP-50 AODD pumps, designed to rebuild the air motor by replacing seals, valves, and other pneumatic components to restore diaphragm actuation and stable airflow in high-cycle systems. The kit includes O-rings, gaskets, pilot valve assemblies, springs, bushings, and a spool valve, and is constructed from elastomers, PTFE, nylon, and composite materials for installation in the air motor/pneumatic section. Common replacements include Yamada K225-AM and K80-AM, and the package weighs around 3 lb; typical applications include chemical processing, wastewater treatment, chemical transfer, coatings, and bulk fluid handling where reliable diaphragm movement and consistent flow output are critical.
