This NDP-50BFN-NPT-NEW is a 2" NDP-50 air-operated diaphragm pump in cast iron, rated to 164 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 158°F (70°C).
Cast iron construction gives the weight and stiffness that heavy transfer work wants, and stands up to abrasive and particulate-laden fluids that wear lighter housings. Buna-N diaphragms and balls suit petroleum oils, diesel, hydraulic fluid and greases, but should be kept away from ketones and strong oxidizers. Ball check valves are the right choice for flooded-suction installations.
Supplied with NPT threaded connections. 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.
