This NDP-25BSC-PP is a 1" NDP-25 air-operated diaphragm pump in stainless steel, rated to 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.
The non-metallic center body and glass-filled polypropylene air motor cut weight and remove a corrosion path in wet or chemically aggressive areas. It self-primes, tolerates running dry, and stalls harmlessly against a closed valve, so it suits batching and intermittent transfer where a centrifugal pump would be a poor fit.
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.
