The NDP-40BFC-NPT is Yamada's 1-1/2" air-operated double-diaphragm pump in cast iron, with a 107 GPM maximum. It passes solids to 9/32" (7 mm) and handles fluid to 180°F (82°C).
A cast iron wetted path suits mining, foundry and heavy-process service where the pump takes physical punishment and the fluid is not corrosive. Neoprene diaphragms and balls give balanced service across mild chemicals, oils and water, and are the economical default where nothing aggressive is being moved. 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.
