The GRACO 648227 Husky 1050A-E is an air-operated double diaphragm pump with a stainless steel (SS) center section, PTFE (PT) balls, and PTFE/Stainless (PS) diaphragms, designed for robust and reliable fluid transfer in industrial applications. It is intended for use with a variety of fluids, including fuels, oils, and waste oils, and is suitable for demanding environments where chemical resistance and durability are required.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050A-E
• Stainless steel center section, PTFE balls, PTFE/Stainless diaphragms, Aluminum or Stainless Steel options available in other models
• Maximum free flow delivery: 50 GPM (189 LPM); typical continuous use flow rate may be lower depending on cycle rate
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal models; some configurations may have lower maximums (e.g., 50 psi or 100 psi for certain packages)
• Compatible with fuels, oils, waste oils, and other industrial fluids; not for use with highly abrasive or corrosive fluids unless specified
• UL-listed for certain models; check specific configuration for certification
• Stall-free low pulsation air valve for smooth and rapid changeover
• Robust construction for long service life
• Easy maintenance with accessible components
• Handles solids up to 1/8 in (3.2 mm)
• Reliable performance in continuous and intermittent duty cycles

Applications:
Used for fuel transfer, oil transfer, waste oil reclamation, and general industrial fluid handling in mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump system.
• Ensure proper alignment of inlet and outlet connections
• Use appropriate thread sealant for NPT connections
• Check air supply pressure and flow rate before operation
• Follow recommended cycle rates for continuous use (typically 93–140 CPM for continuous duty, 20 CPM for circulation systems)
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed
• Periodically check for leaks and tighten connections
• Lubricate moving parts as recommended
• Replace worn or damaged components with genuine GRACO parts
• Keep pump and surrounding area clean to prevent contamination
