ARO® PD30A-AAS-GGG-C

ARO® EXP Series 3" Metallic Diaphragm Pump, 275 GPM, Standard Pump Style, Aluminum Center Body, 3 - 8 NPTF Fluid Connections, Aluminum Wetted Parts, Stainless Steel Hardware, Nitrile Seat & Ball, Buna-N Diaphragm

The ultimate in heavy-duty pump design, the ARO® EXP 3" metallic diaphragm pumps achieve flow rates up to 275 GPM and have up to 4 times the life of traditional diaphragm pumps due to the EXP's new convoluted diaphragm design. ARO® EXP Series diaphragm pumps include all the benefits of standard air-operating pumps, but with significant additional features and benefits. The patented SimulShift™ "unstallable" air balanced valve design avoids stalling issues associated with other pumps. Quick Dump™ check valves divert cold exhaust air from ice-prone components to prevent downtime due to freezing. Modular designs add simplified serviceability and ease of upgrades to solenoid operation, flow monitoring and leak detection functionality.
