The Yamada NDP-80BAS is an industrial-grade 3-inch air-operated double diaphragm pump engineered for high-volume transfer of abrasive slurries, mild chemicals, paints, adhesives, and industrial process fluids. Featuring standard ANSI Flange connections for direct, leak-free pipe integration, this heavy-duty pump pairs a durable cast Aluminum body with highly resilient Santoprene® (TPO) diaphragms and check valves. This material combination delivers superior mechanical flex life, outstanding abrasion resistance, and reliable fluid containment across demanding processing applications. Driven by Yamada’s patented, oil-free C-Spool air-valve technology, this dependable AODD unit guarantees stall-free, non-lubricated operation under continuous duty cycles. Capable of output flow rates up to 215 GPM while handling suspended solids up to 13/32”, the NDP-80BAS provides a seal-less, explosion-proof fluid transfer solution tailored for paint and coating manufacturing, municipal and industrial water treatment, filter press feeding, and bulk fluid management.
