The Yamada NDP-80BPE is an industrial-grade 3-inch air-operated double diaphragm (AODD) pump engineered for high-volume transfer of water-based fluids, mild acids, caustics, alkaline solutions, and abrasive slurries. Featuring standard ANSI Flange connections for direct, leak-free pipe integration, this heavy-duty pump pairs a chemically resistant Polypropylene body with highly resilient EPDM diaphragms and seals. This material pairing delivers excellent flexibility, outstanding weather and chemical resistance, and extended service life when handling polar solvents and corrosive wastewater. Driven by Yamada’s patented, oil-free C-Spool air-valve technology, this reliable AODD unit guarantees stall-free, non-lubricated performance under continuous duty cycles. Capable of output flow rates up to 215 GPM while handling suspended solids up to 13/32”, the NDP-80BPE provides a seal-less, explosion-proof fluid transfer solution designed for municipal and industrial wastewater treatment, chemical distribution, utility lines, and mining applications.
