Yamada's NDP-15FVT is a 1/2" AODD pump in kynar pvdf, moving up to 13.5 GPM. It passes solids to 1/32" (1 mm) and handles fluid to 212°F (100°C).
Kynar (PVDF) resists concentrated acids, halogens and aggressive solvents that attack polypropylene, and carries a higher temperature ceiling than PP. PTFE diaphragms and balls give near-universal chemical resistance, covering solvents, concentrated acids and oxidizers that destroy rubber elastomers, at the cost of a slightly lower displacement per stroke. Flat check valves are the right choice where the pump has to lift liquid rather than being fed by gravity.
Air drive means no electrics at the pump, seal-less operation with nothing to leak at a shaft, and safe stalling against a closed discharge.
Ordered online, shipped from Texas, priced well and backed by US support before and after the sale. Send us your application details if you want a second opinion on materials.
