Yamada builds the G25AS11 as a 1" double-diaphragm pump in aluminum, capable of 40.1 GPM. It passes solids to 1/8" (3 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. 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. 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.
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.
