Yamada America DP-20F High Purity 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 corrosive and contamination-sensitive liquids using compressed air. It is commonly installed in semiconductor, chemical processing, and ultrapure fluid systems where PTFE construction prevents metal contamination and ensures chemical compatibility. Maintenance teams, OEMs, and integrators purchase this pump for replacement of critical fluid transfer equipment, new system builds, and retrofit of high-purity process lines.

Applications:

The Yamada DP-20F diaphragm pump is used in high purity industrial environments where contamination control and chemical resistance are critical. It is commonly deployed in semiconductor manufacturing, ultrapure chemical transfer, pharmaceutical processing, and specialty coating systems where fluoropolymer wetted parts prevent metal ion contamination and ensure safe handling of aggressive fluids such as acids and alkalis.
