The NDP-50BSW-NPT covers 2" transfer duty as an air-operated double-diaphragm pump in stainless steel, rated to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 212°F (100°C).
316 stainless wetted parts take the aggressive chemicals and elevated-temperature service that aluminum cannot, and clean up for food, beverage and pharmaceutical work. Yamada's Ultimate two-piece diaphragm pairs a PTFE wetted face with an elastomer backer, giving PTFE chemical resistance with markedly longer flex life than solid PTFE. Ball check valves are the right choice for flooded-suction installations.
Supplied with NPT threaded connections. 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.
