Yamada Pump NDP-80BFC

The Yamada NDP-80BFC is a heavy-duty air operated diaphragm pump engineered for high-volume general fluid transfer, slurries, and industrial applications. Built with a rugged cast iron housing, 3" NPT ports, and resilient Neoprene (C) diaphragms and check balls, this high-performance AODD pump delivers flow rates up to 215 GPM with exceptional reliability. Powered by Yamada’s patented non-lubricated C-Spool air valve system, the Yamada AODD NDP-80BFC eliminates stalling and maintenance downtime while providing safe, leak-free, bolted construction for demanding process environments.

Yamada Air-Operated Double Diaphragm Pumps

Engineered for High Performance. Manufactured to Last.

• Leak-Free Bolted Construction: Built for heavy-duty reliability, Yamada’s bolted design ensures precise alignment and effortless reassembly—eliminating the leaks and tedious rebuilds common with clamp-band retainers.
• Externally Accessible Air Valve: Perform quick inspections or routine maintenance directly in-line, without taking the pump out of service.
• Unified Valve Architecture: Standardized air valve assemblies across pump models reduce part confusion and lower inventory overhead.
• Maintenance-Free Pilot Valve: Yamada’s unique modular pilot valve uses an inner center-disk mechanism to trigger valve shifting with zero hassle. Free of dynamic O-rings or awkward snap rings, it requires no routine repairs.
