The GRACO Husky 1050 is an air-operated double diaphragm pump designed for industrial fluid transfer. This specific model features a stainless steel (SS) pump body, aluminum (AL) center section, stainless steel seats and balls, and a polypropylene (PO) diaphragm. It is intended for use in environments requiring flameproof motors (C1D1 certification) and is suitable for transferring water, antifreeze, fuel, and other compatible fluids.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050, 1 in. (25.4 mm) NPT
• Stainless steel (SS) pump body, aluminum (AL) center section, stainless steel (SS) seats and balls, polypropylene (PO) diaphragm
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal models; some sources list 100 psi (7 bar, 0.7 MPa) for certain configurations
• Suitable for water, antifreeze, fuel, and other compatible fluids; maximum pumpable solids: 1/8 in (3.2 mm)
• C1D1 Flameproof Motor (for this specific configuration); UL listed for other Husky 1050 models
• Stall-free low pulsation air valve for smooth and rapid changeover
• Reliable and robust construction for industrial environments
• Easy to maintain with accessible components
• Handles abrasive and corrosive fluids due to SS and PO materials
• High suction lift capability: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet

Applications:
Industrial fluid transfer, including water, antifreeze, fuel, and other compatible liquids in environments requiring flameproof equipment. Suitable for mining, agriculture, and other sectors with demanding fluid handling needs.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment. Non-genuine parts may compromise reliability and safety, especially in hazardous environments.
• Ensure all connections are secure and leak-free before operation
• Verify that the pump is properly grounded and that electrical components meet local safety standards
• Check that the air supply is clean and dry to prevent damage to internal components
• Follow all manufacturer guidelines for installation and maintenance
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
