Yamada Pump NDP-800BSV

The Yamada NDP-800BSV is a heavy-duty, ultra-high-capacity 3-inch air-operated double diaphragm pump engineered for demanding high-volume fluid transfer and severe chemical environments. Equipped with female 3-inch ANSI Flange connections, it offers a secure, leak-free connection tailored for heavy-duty threaded piping systems. Featuring a cast 316 stainless steel housing paired with high-performance FKM (Viton) diaphragms, this pump provides maximum dynamic sealing, exceptional thermal durability, and superior resistance to aggressive chemicals, acids, hydrocarbons, and harsh solvents. Powered by Yamada’s patented, oil-free C-Spool air-valve technology with a built-in reset button, the NDP-800BSV guarantees reliable, stall-free operation without requiring air motor lubrication or high maintenance downtime. Capable of delivering maximum flow rates exceeding 300 GPM while passing suspended solids up to 13/32” (10 mm), this seal-less liquid handling unit is an ideal solution for chemical processing, petrochemical refining, solvent recovery, and corrosive fluid handling across industrial applications.
