The GRACO 649532 (likely a variant of the Husky 1050 series) is an air-operated double diaphragm pump designed for transferring a wide range of fluids. It features a polypropylene (PP) center section and PTFE (polytetrafluoroethylene) diaphragms and balls, making it suitable for handling aggressive chemicals and slurries. This pump is intended for use in demanding industrial applications such as lubrication, chemical transfer, and process fluid handling within GRACO equipment.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050 (likely 1" NPT/BSP ports, based on similar models)
• Polypropylene (PP) center section, PTFE diaphragms and balls
• Maximum free flow: 189 lpm (50 US Gpm)
• Maximum working pressure: 8.6 Barg (125 Psig)
• Compatible with a wide range of fluids, including aggressive chemicals and slurries
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Up to 5 times longer diaphragm life compared to other diaphragm pumps in its class
• Spring-loaded, externally serviceable pilot valves for faster changeover and reduced pulsation
• Modular air valve design for ease of maintenance
• Four bolt joint design for robust construction

Applications:
Chemical transfer, lubrication, process fluid handling, slurry pumping, and other industrial fluid transfer applications

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure correct alignment of inlet and outlet ports
• Use appropriate fittings and gaskets for the intended fluid
• Follow manufacturer guidelines for air supply pressure and flow
• Regularly inspect diaphragms and valves for wear and replace as needed
• Lubricate air valve components if required (though Husky 1050 is typically no-lube design)
• Check for leaks and tighten connections as necessary
