The Yamada NDP-50BPC is an economical, non-metallic 2-inch air operated diaphragm pump engineered for continuous, high-volume transfer of general process chemicals, utility water, and mild industrial slurries. Built with a chemical-resistant Polypropylene fluid casing and flexible Neoprene (C) diaphragms, this heavy-duty pump offers outstanding mechanical fatigue resistance, high flex life, and reliable wear performance. Driven by Yamada’s patented, oil-free C-Spool air-valve technology, this non-metallic Yamada AODD unit ensures non-lubricated, stall-free operation across continuous duty cycles. Delivering flow rates up to 140 GPM while passing suspended solids up to 5/16”, the NDP-50BPC-PP AODD pump offers a seal-less, leak-proof, and fully chemical-resistant fluid transfer solution for industrial wastewater treatment, plant utility circulation, dewatering, and general chemical manufacturing lines.
