YAMADA DP-20F DIAPHRAGM PUMP DP20F

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 ultrapure fluid transfer systems where non-metallic construction and chemical resistance are required. Maintenance teams, OEMs, and integrators purchase this pump for new system builds, replacement of failed pumps, and retrofit of high-purity fluid handling applications requiring contamination-free operation.

Applications:

The Yamada DP-20F diaphragm pump is used in high purity industrial environments where contamination control and corrosion resistance are critical. It is commonly deployed in semiconductor manufacturing, chemical dosing systems, pharmaceutical processes, and specialty coating applications where PTFE/PFA wetted parts prevent metal ion contamination and ensure safe transfer of aggressive chemicals such as acids and alkalis.
