The Yamada NDP-50BVS-PP is a 2" air-operated double-diaphragm pump in kynar pvdf, rated to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 212°F (100°C).
The Kynar PVDF wetted path is specified for concentrated sulfuric, hydrochloric and nitric service, and for hot chemicals beyond what polypropylene tolerates. Santoprene diaphragms and balls offer broad chemical compatibility with a long flex life, and are usually the best value where the duty cycle is heavy. Ball check valves are the right choice for flooded-suction installations.
The non-metallic center body and glass-filled polypropylene air motor cut weight and remove a corrosion path in wet or chemically aggressive areas. It runs on plant air with no electrical supply at the pump, self-primes, and will sit stalled against a closed discharge without damage — useful on intermittent or dead-headed duty.
