Yamada's G15PS11 is a 1/2" AODD pump in polypropylene, moving up to 16.6 GPM. It passes solids to 1/32" (1 mm) and handles fluid to 180°F (82°C).
Polypropylene construction gives broad resistance to inorganic acids and caustics at a lower cost than fluoropolymer, and it stays inert in the salt and chlorine service that corrodes metal pumps. 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 runs on plant air with no electrical supply at the pump, self-primes, and will sit stalled against a closed discharge without damage — useful on intermittent or dead-headed duty.
