The Yamada G15SS11 is a 1/2" air-operated double-diaphragm pump in stainless steel, rated to 16.6 GPM. It passes solids to 1/32" (1 mm) and handles fluid to 180°F (82°C).
A 316 stainless wetted path resists chlorides, organic acids and most process chemicals, and is the standard specification wherever wash-down or product purity matters. Santoprene diaphragms and balls offer broad chemical compatibility with a long flex life, and are usually the best value where the duty cycle is heavy. 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.
