YAMADA NDP-20BPT 1/4 Inch Corrosion Resistant Pump

The YAMADA NDP-20BPT is a compact 1/4 inch air operated double diaphragm pump designed for transferring corrosive and chemically aggressive fluids.

Featuring a PTFE diaphragm and PTFE wetted components, this pump provides excellent chemical resistance and reliable performance in applications requiring stable fluid transfer and material compatibility.

The pneumatic diaphragm design operates without electrical power and eliminates rotating seals, reducing leakage risks while providing flexible installation options.

Compared with general-purpose diaphragm pumps, the NDP-20BPT is optimized for applications where corrosion resistance and chemical compatibility are critical.
