Yamada's NDP-20BAN-PP is a 3/4" AODD pump in aluminum, moving up to 31.7 GPM. It passes solids to 1/16" (2.0 mm) and handles fluid to 180°F (82°C).
Aluminium construction handles solvents, lubricating oils and hydrocarbon-based fluids well, and takes mechanical abuse better than a plastic body in a busy plant. Buna-N diaphragms and balls suit petroleum oils, diesel, hydraulic fluid and greases, but should be kept away from ketones and strong oxidizers. 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.
