The NDP-25BSH covers 1" transfer duty as an air-operated double-diaphragm pump in stainless steel, rated to 46.2 GPM. It passes solids to 1/8" (3 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.
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.
