This NDP-40BAE is a 1-1/2" NDP-40 air-operated diaphragm pump in aluminum, rated to 107 GPM. It passes solids to 9/32" (7 mm) and handles fluid to 212°F (100°C).
Aluminium construction handles solvents, lubricating oils and hydrocarbon-based fluids well, and takes mechanical abuse better than a plastic body in a busy plant. EPDM diaphragms and balls handle acids, caustics, ketones and alcohols well — but not petroleum products, which swell the elastomer. 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.
