The Graco Husky 1050 649034 is a high-capacity air operated double diaphragm pump designed for industrial fluid transfer, chemical processing, wastewater handling, and compatible coating applications. This configuration uses a polypropylene fluid section and polypropylene center section with PTFE balls, polypropylene seats, and two-piece PTFE/EPDM diaphragms.
The pump delivers a maximum flow rate of 189 L/min and can operate at pressures up to 8.6 bar. Its 1 in. female NPT fluid inlet and outlet support higher-volume transfer lines, while the 1/2 in. female NPT air inlet provides pneumatic power for stable operation.
The one-piece polypropylene center section helps reduce air-leak points, while the modular low-pulsation air valve supports smooth changeover and reliable continuous operation. The four-bolt construction provides even sealing pressure between pump components.
The 649034 is suitable for compatible acids, alkalis, detergents, process water, wastewater, slurry-containing liquids, and industrial fluids. Material compatibility must be verified before installation because the wetted components include polypropylene, PTFE, and EPDM.
