The GRACO 651458 Husky 1050 SS is a stainless steel air-operated double diaphragm pump designed for reliable fluid transfer in demanding industrial environments. It is constructed with stainless steel wetted parts for enhanced durability and chemical resistance, making it suitable for handling water, antifreeze, fuel, and other compatible fluids within GRACO equipment and systems.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050 SS (1-inch port size)
• Stainless steel wetted parts, metal construction
• Maximum free flow: 189 lpm (50 US GPM)
• Maximum working pressure: 8.6 bar (125 psi)
• Compatible with water, antifreeze, fuel, and other compatible fluids; suitable for industrial and vehicle service applications
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Spring-loaded, externally serviceable pilot valves for faster changeover and reduced pulsation
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps in its class
• Handles solids up to 3.2 mm (1/8 inch) in size
• Modular air valve for easy maintenance

Applications:
Ideal for transferring water, antifreeze, fuel, and other compatible fluids in industrial, vehicle service, and maintenance applications. Suitable for environments requiring robust, leak-resistant, and low-maintenance fluid transfer solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of inlet and outlet connections
• Use appropriate fittings and seals for the intended fluid and pressure
• Follow recommended air supply requirements (maximum air consumption: 67 scfm)
• Regularly inspect and maintain pilot valves and diaphragms for optimal performance
• Refer to the manual for specific installation and maintenance procedures
