Yamada's NDP-15BSN is a 1/2" AODD pump in stainless steel, moving up to 13.5 GPM. It passes solids to 1/32" (1 mm) and handles fluid to 180°F (82°C).
316 stainless construction is specified where corrosion resistance and cleanability both matter — dairy, brewing, fine chemicals and pharmaceutical transfer. 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 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.
