The NDP-20BAW-PP is Yamada's 3/4" air-operated double-diaphragm pump in aluminum, with a 31.7 GPM maximum. It passes solids to 1/16" (2.0 mm) and handles fluid to 212°F (100°C).
An aluminum wetted path is the workhorse choice for petroleum products, inks, adhesives and machine coolant, giving metal durability without the cost of 316. Yamada's Ultimate two-piece diaphragm pairs a PTFE wetted face with an elastomer backer, giving PTFE chemical resistance with markedly longer flex life than solid PTFE. Ball check valves are the right choice for flooded-suction installations.
The non-metallic center body and glass-filled polypropylene air motor cut weight and remove a corrosion path in wet or chemically aggressive areas. The pump self-primes, handles a degree of entrained air, and holds pressure when stalled, which makes it forgiving on transfer duty that starts and stops.
Texas-based, with short lead times and pricing that reflects our supply position. Not sure this is the right build? Send us the fluid and duty and we will confirm.
