This G50AT11 is a 2" G50 air-operated diaphragm pump in aluminum, rated to 193 GPM. It passes solids to 5/16" (8 mm) and handles fluid to 212°F (100°C).
Aluminium construction handles solvents, lubricating oils and hydrocarbon-based fluids well, and takes mechanical abuse better than a plastic body in a busy plant. 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.
