This NDP-80BPE is a 3" NDP-80 air-operated diaphragm pump in polypropylene, rated to 215 GPM. It passes solids to 13/32" (10 mm) and handles fluid to 180°F (82°C).
A glass-filled polypropylene wetted path handles dilute acids, alkalis and brines without the galvanic issues a metal body brings, making it the usual pick for chemical transfer and wastewater duty. 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.
Air drive means no electrics at the pump, seal-less operation with nothing to leak at a shaft, and safe stalling against a closed discharge.
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.
