Yamada builds the NDP-40BFH-NPT as a 1-1/2" double-diaphragm pump in cast iron, capable of 107 GPM. It passes solids to 9/32" (7 mm) and handles fluid to 248°F (120°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. Hytrel diaphragms and balls carry the highest temperature rating in the range and resist abrasion well, which suits hot oils and particulate-bearing fluids. 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.
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.
