The NDP-15FVT-D is Yamada's 1/2" air-operated double-diaphragm pump in kynar pvdf, with a 13.5 GPM maximum. 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.
Supplied as a drum-mount package with dip tube and bung adapter. It self-primes, tolerates running dry, and stalls harmlessly against a closed valve, so it suits batching and intermittent transfer where a centrifugal pump would be a poor fit.
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.
