Yamada America DP-20F Air Operated Diaphragm Pump

Description:

The Yamada DP-20F is a high purity air-operated double diaphragm (AODD) pump used in industrial fluid handling systems to transfer sensitive and contamination-critical liquids using compressed air. It is commonly used in semiconductor, chemical processing, and clean fluid transfer applications where material purity and chemical resistance are essential. Maintenance teams, OEMs, and integrators purchase this pump for new system builds, replacement of failed units, and retrofit of high-purity fluid handling systems.

Applications:

The Yamada DP-20F diaphragm pump is used in high purity industrial environments where contamination control and chemical compatibility are critical. It is commonly deployed in semiconductor manufacturing, ultrapure chemical transfer, pharmaceutical processing, and specialty coating systems where non-metallic wetted parts and clean fluid pathways are required for process integrity and reliability.
