The GRACO 651532 Husky 1050 is an air-operated double diaphragm pump featuring a vertical outlet, stainless steel (SS) pump body, aluminum (AL) center section, SS seats, SS balls, and a TPE (thermoplastic elastomer) diaphragm. It is designed for reliable transfer of fluids such as water, antifreeze, fuel, and other compatible liquids in industrial and vehicle service applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050 (1 in. inlet/outlet, vertical outlet configuration)
• Stainless steel (SS) pump body, aluminum (AL) center section, SS seats, SS balls, TPE diaphragm
• Maximum free-flow delivery: 189 l/min (50 gpm) (varies by configuration and pressure; some listings specify 38 gpm for certain models, but 50 gpm is the highest published for Husky 1050 series)
• Maximum fluid working pressure: up to 125 psi (8.6 bar, 0.86 MPa) for metal pumps; some listings specify 50 psi (0.35 MPa) for certain models, but 125 psi is the maximum for Husky 1050 metal pumps
• Compatible with water, antifreeze, fuel, and other compatible fluids; not for use with incompatible chemicals or highly abrasive media
• UL listed (varies by model and configuration)
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section reduces leaks and maintenance
• Vertical outlet for specific installation requirements
• Durable construction for industrial environments
• Handles solids up to 3.2 mm (1/8 in) in size
• Maximum suction lift: 4.9 m (16 ft) dry, 8.8 m (29 ft) wet
• Maximum pump speed: 280 cpm

Applications:
Industrial fluid transfer, vehicle service (oil evacuation, oil transfer), water, antifreeze, and fuel transfer in mining, agriculture, and other heavy-duty environments

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 thread sealant or gaskets for leak-free installation
• Follow recommended air pressure and flow settings for optimal performance
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
• Refer to the specific installation manual for vertical outlet models to ensure correct orientation and mounting
• Periodically check for leaks and tighten connections as necessary
• Replace diaphragms and seals according to the maintenance schedule
• Clean pump internals if handling fluids with suspended solids
• Lubricate moving parts as recommended by GRACO
