The GRACO 648071 Husky 1050A-E is an air-operated double diaphragm pump designed for industrial applications. It features a robust construction with FKM (Fluoroelastomer) ball material and is engineered for reliable transfer of a wide range of fluids, including those requiring chemical resistance and durability in demanding environments[1][2][5].

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050A-E, 1" connection (model/size may vary by configuration)
• Industrial-grade; ball material: FKM (Fluoroelastomer); center section and fluid section materials may vary (aluminum, stainless steel, Hastelloy, etc.)
• Up to 50 GPM (189 LPM)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa); maximum air input pressure: 125 psi (8.6 bar, 0.86 MPa)
• Industrial fluids, antifreeze, detergents, motor oil, hydraulic fluid, cutting oil, water, wastewater transfer
• Durable, bolted design for even sealing and easy maintenance
• Handles solids up to 1/8 in. (3.2 mm)
• Maximum cycle rate: 280 cycles per minute
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet
• Reliable performance in harsh environments
• Easy to disassemble and maintain

Applications:
Industrial fluid transfer, chemical processing, wastewater management, lubrication systems, mining, agriculture, and other heavy-duty applications

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure correct alignment of inlet and outlet connections
• Use appropriate thread sealant for NPT connections
• Verify air supply pressure does not exceed maximum rated pressure
• Inspect diaphragms and balls regularly for wear and replace as needed
• Follow GRACO’s recommended maintenance schedule for best results
