Yamada's NDP-20BAE-D 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 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. EPDM diaphragms and balls handle acids, caustics, ketones and alcohols well — but not petroleum products, which swell the elastomer. Ball check valves are the right choice for flooded-suction installations.
Supplied as a drum-mount package with dip tube and bung adapter. Being air-driven, it needs no motor starter or electrical classification at the pump, self-primes from dry, and can be dead-headed and left stalled under pressure.
We ship from Texas, quote honest lead times and price sharply. Tell us the fluid, temperature and flow you need and we will confirm the right configuration before you order.
