The GRACO 648007 HUSKY PUMP, 1050A-E, BN/BN/BN/4A is an industrial-grade air-operated double diaphragm pump designed for reliable fluid transfer. It features a Buna ball material and is engineered for robust performance in demanding environments. The pump is commonly used for transferring a variety of fluids, including fuels and other industrial liquids, and is suitable for applications requiring high flow rates and the ability to handle small solids[1][2][5].

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050A-E
• Aluminum body, Buna ball material, TPE diaphragms, Nitrile Rubber seats (varies by configuration)
• Up to 50 GPM (189 LPM) depending on configuration and application[2][5]
• Maximum fluid working pressure: 100–125 psi (0.7–0.86 MPa, 7.0–8.6 bar) depending on configuration[2][5]
• Industrial fluids, fuels, compatible with systems requiring 1 in. NPT connections[5]
• UL listed[3][5]
• Stall-free low pulsation air valve for smooth operation
• High flow rate and robust construction for industrial use
• Capable of handling solids up to 1/8 in. (3.2 mm)
• Easy maintenance and reliable performance
• Suitable for continuous and intermittent duty cycles

Applications:
Industrial fluid transfer, fuel transfer, fluid reclamation, circulation systems, and applications requiring reliable pumping of liquids with small solids[2][3][5].

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting of the pump
• Use recommended air pressure (20–100 psi, 0.14–0.7 MPa) for safe operation[5]
• Connect fluid lines using 1 in. NPT fittings as specified[5]
• Follow manufacturer guidelines for maintenance intervals and diaphragm inspection
• Use appropriate wall brackets or mounting kits for secure installation
