This NDP-50BAC is a 2" NDP-50 air-operated diaphragm pump in aluminum, rated to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 180°F (82°C).
An aluminum wetted path is the workhorse choice for petroleum products, inks, adhesives and machine coolant, giving metal durability without the cost of 316. 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 pump self-primes, handles a degree of entrained air, and holds pressure when stalled, which makes it forgiving on transfer duty that starts and stops.
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.
