The NDP-15BAS is Yamada's 1/2" air-operated double-diaphragm pump in aluminum, with a 13.5 GPM maximum. It passes solids to 1/32" (1 mm) and handles fluid to 180°F (82°C).
The aluminum body suits solvents, fuels, oils and paints — the general-industrial fluids where a metal pump is wanted but stainless is more than the job needs. Santoprene diaphragms and balls offer broad chemical compatibility with a long flex life, and are usually the best value where the duty cycle is heavy. Ball check valves are the right choice for flooded-suction installations.
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.
