The G15VT11 covers 1/2" transfer duty as an air-operated double-diaphragm pump in kynar pvdf, rated to 16.6 GPM. It passes solids to 1/32" (1 mm) and handles fluid to 212°F (100°C).
The Kynar PVDF wetted path is specified for concentrated sulfuric, hydrochloric and nitric service, and for hot chemicals beyond what polypropylene tolerates. PTFE diaphragms and balls give near-universal chemical resistance, covering solvents, concentrated acids and oxidizers that destroy rubber elastomers, at the cost of a slightly lower displacement per stroke. 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. The pump self-primes, handles a degree of entrained air, and holds pressure when stalled, which makes it forgiving on transfer duty that starts and stops.
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.
