The NDP-80BSC covers 3" transfer duty as an air-operated double-diaphragm pump in stainless steel, rated to 215 GPM. It passes solids to 13/32" (10 mm) and handles fluid to 180°F (82°C).
316 stainless wetted parts take the aggressive chemicals and elevated-temperature service that aluminum cannot, and clean up for food, beverage and pharmaceutical work. 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.
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.
