The Yamada NDP-25BAC-PP is a 1" air-operated double-diaphragm pump in aluminum, rated to 46.2 GPM. It passes solids to 1/8" (3 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. Neoprene diaphragms and balls give balanced service across mild chemicals, oils and water, and are the economical default where nothing aggressive is being moved. 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. It self-primes, tolerates running dry, and stalls harmlessly against a closed valve, so it suits batching and intermittent transfer where a centrifugal pump would be a poor fit.
Shipped from Texas with short lead times and strong pricing. If you are unsure which build fits your fluid, send us the application details and we will point you at the right part number.
