This NDP-25BAH-PP is a 1" NDP-25 air-operated diaphragm pump in aluminum, rated to 46.2 GPM. It passes solids to 1/8" (3 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.
The non-metallic center body and glass-filled polypropylene air motor cut weight and remove a corrosion path in wet or chemically aggressive areas. 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.
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.
