Yamada builds the NDP-20BSC as a 3/4" double-diaphragm pump in stainless steel, capable of 31.7 GPM. It passes solids to 1/16" (2.0 mm) and handles fluid to 180°F (82°C).
316 stainless construction is specified where corrosion resistance and cleanability both matter — dairy, brewing, fine chemicals and pharmaceutical transfer. Neoprene diaphragms and balls give balanced service across mild chemicals, oils and water, and are the economical default where nothing aggressive is being moved. 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.
