Yamada builds the NDP-25BVV-PN-FLANGE as a 1" double-diaphragm pump in kynar pvdf, capable of 46.2 GPM. It passes solids to 1/8" (3 mm) and handles fluid to 212°F (100°C).
PVDF construction handles the aggressive oxidising chemistry — chlorine, bromine, strong mineral acids — where polypropylene reaches its limit. Viton diaphragms and balls are chosen for aggressive chemicals and hot fluids — aromatic solvents, chlorinated hydrocarbons and concentrated acids. Ball check valves are the right choice for flooded-suction installations.
Fitted with flanged manifolds rather than threaded connections. Being air-driven, it needs no motor starter or electrical classification at the pump, self-primes from dry, and can be dead-headed and left stalled under pressure.
Texas-based, with short lead times and pricing that reflects our supply position. Not sure this is the right build? Send us the fluid and duty and we will confirm.
