The GRACO 648228 HUSKY PUMP, 1050A-E, SP/SP/SP/6A is an air-operated double diaphragm pump designed for industrial applications. It features a robust construction with Santoprene ball material and is intended for reliable fluid transfer, including oils and waste oils, in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050A-E
• Industrial-grade, with Santoprene ball material
• Up to 50 GPM (189 LPM) for metal versions; some configurations may have lower flow rates (e.g., 38 GPM for certain UL-listed models)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal versions; some configurations may have lower pressure ratings (e.g., 50 psi for certain UL-listed models)
• Designed for use with oils, waste oils, and compatible with a range of industrial fluids
• UL-listed for certain models; check specific configuration for certification
• Stall-free low pulsation air valve for smooth operation
• Bolted design for even sealing and easy maintenance
• Reliable performance in harsh environments
• Handles solids up to 1/8 in. (3.2 mm) in size
• Easy to maintain and service

Applications:
Industrial fluid transfer, oil and waste oil handling, fluid reclamation, and general-purpose pumping in mining, agriculture, and manufacturing 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 and secure mounting of the pump
• Use recommended air pressure (typically 20–100 psi, depending on configuration)
• Check all connections for leaks before operation
• Follow manufacturer guidelines for diaphragm and seat replacement
• Regularly inspect and maintain diaphragms, seats, and balls for wear
• Regularly check and replace diaphragms and seats as needed
• Inspect for leaks and unusual noises during operation
• Keep air supply clean and dry to prevent contamination
• Follow recommended cycle rates for continuous use (e.g., 93–140 CPM for continuous use, 20 CPM for circulation systems)
