The Yamada NDP-50BAH is a 2" air-operated double-diaphragm pump in aluminum, rated to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 248°F (120°C).
The aluminum body suits solvents, fuels, oils and paints — the general-industrial fluids where a metal pump is wanted but stainless is more than the job needs. 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.
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.
