The Yamada NDP-50BPS is an advanced, non-metallic 2-inch air operated diaphragm pump engineered for high-volume transfer of abrasive chemical slurries, acidic suspensions, and corrosive process fluids. Built with a chemical-resistant Polypropylene fluid casing and durable Santoprene® (TPO) diaphragms, this heavy-duty unit offers outstanding abrasion resistance, mechanical toughness, and long flex fatigue life. Driven by Yamada’s patented, oil-free C-Spool air-valve technology, this non-metallic Yamada AODD unit ensures non-lubricated, stall-free performance across continuous processing cycles. Capable of output flow rates up to 140 GPM while handling suspended solids up to 5/16”, the NDP-50BPS-PP AODD pump provides a seal-less, leak-proof, and fully chemical-resistant fluid transfer solution for chemical manufacturing, industrial wastewater treatment, metal finishing, and hazardous slurry handling.
