Yamada's NDP-50BSH-NPT is a 2" AODD pump in stainless steel, moving up to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 248°F (120°C).
316 stainless construction is specified where corrosion resistance and cleanability both matter — dairy, brewing, fine chemicals and pharmaceutical transfer. 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. It self-primes, tolerates running dry, and stalls harmlessly against a closed valve, so it suits batching and intermittent transfer where a centrifugal pump would be a poor fit.
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.
