Yamada's NDP-50BFH-NPT-NEW is a 2" AODD pump in cast iron, moving up to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 248°F (120°C).
The cast iron body is built for heavy industrial duty — waste oils, sludges and abrasive slurries where mass and rigidity matter more than corrosion resistance. 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.
Stocked and shipped from Texas with fast dispatch and competitive pricing. Send over your application details if you want the material selection checked before ordering.
