The NDP-50BSC covers 2" transfer duty as an air-operated double-diaphragm pump in stainless steel, rated to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 180°F (82°C).
A 316 stainless wetted path resists chlorides, organic acids and most process chemicals, and is the standard specification wherever wash-down or product purity matters. 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.
Ordered online, shipped from Texas, priced well and backed by US support before and after the sale. Send us your application details if you want a second opinion on materials.
