Yamada builds the NDP-25BSC as a 1" double-diaphragm pump in stainless steel, capable of 46.2 GPM. It passes solids to 1/8" (3 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.
Being air-driven, it needs no motor starter or electrical classification at the pump, self-primes from dry, and can be dead-headed and left stalled under pressure.
