Yamada's NDP-50BFS-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. Santoprene diaphragms and balls offer broad chemical compatibility with a long flex life, and are usually the best value where the duty cycle is heavy. Ball check valves are the right choice for flooded-suction installations.
Supplied with NPT threaded connections. It runs on plant air with no electrical supply at the pump, self-primes, and will sit stalled against a closed discharge without damage — useful on intermittent or dead-headed duty.
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.
