Yamada's NDP-50BFE-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 212°F (100°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. EPDM diaphragms and balls handle acids, caustics, ketones and alcohols well — but not petroleum products, which swell the elastomer. 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.
