Yamada K225-AM Air Motor Reseal Kit K225AM

Description:

The Yamada K225-AM is an air motor reseal kit used in air-operated double diaphragm (AODD) pump systems to restore sealing, airflow control, and internal pneumatic components. It is commonly used in Yamada NDP-20 and NDP-25 series pumps where proper air motor function is critical for diaphragm actuation and continuous operation. Maintenance teams, OEMs, and integrators purchase this kit for preventative maintenance, pump rebuilds, and replacement of worn seals and internal air motor components.

Applications:

The Yamada K225-AM repair kit is used in industrial fluid handling environments where AODD pumps operate under continuous or high-cycle conditions. It is commonly deployed in chemical processing, wastewater treatment, coatings, and fluid transfer systems where maintaining proper air motor sealing and valve function ensures consistent diaphragm movement, stable flow output, and reduced downtime.
