Yamada's NDP-50BSE-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 212°F (100°C).
A 316 stainless wetted path resists chlorides, organic acids and most process chemicals, and is the standard specification wherever wash-down or product purity matters. 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.
Texas-based, with short lead times and pricing that reflects our supply position. Not sure this is the right build? Send us the fluid and duty and we will confirm.
