Yamada NDP-15 air-operated diaphragm pump, 1/2", up to 51 L/min

Yamada NDP-15 is a popular industrial size of air-operated double diaphragm pump: flow up to 13.5 gpm (51 L/min), 1/2" NPT port, solids up to 0.8 mm, air pressure 1.4–7 bar.

Body in PP, PVDF, aluminium or AISI 316 stainless steel, diaphragms in CR, NBR, Hytrel, Santoprene or PTFE. Model example NDP-15FPT — polypropylene with PTFE diaphragm. Split manifold (NDP-15FPT-Z) and drum NDP-15*-D versions are available.

Model code example: NDP-25BPT — NDP-25 series, B — ball valve, P — polypropylene, T — PTFE diaphragm; suffixes: -FLG flange, -HP 2:1 pressure, -D drum version, -Z split manifold, -FDA food grade version.
