Yamada builds the G15AN11 as a 1/2" double-diaphragm pump in aluminum, capable of 16.6 GPM. 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. 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 come as standard across the Global Series.
The Global Series air motor uses Yamada's S-Spool valve with no pilot valve and runs completely oil-free, so there are fewer parts to fail and no lubricator to maintain. 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.
Texas-based, with short lead times and pricing that reflects our supply position. Not sure this is the right build? Send us the fluid and duty and we will confirm.
