The GRACO 648093 HUSKY PUMP,1050A-E,SP/SP/SP/4D is an industrial-grade, air-operated double diaphragm pump designed for reliable fluid transfer in demanding environments. The pump features a robust aluminum construction and is intended for use with a variety of industrial fluids, offering smooth, low-pulsation operation and the ability to handle solids up to 1/8 inch in size.

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050A-E
• Aluminum (center section), Santoprene balls, SP (specific material for seats and diaphragms—likely Santoprene or similar, as per SP/SP/SP/4D designation)
• Up to 50 GPM (189 LPM) for standard Husky 1050 models; some listings specify 38 GPM for certain configurations[1][4][5]
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for standard Husky 1050 metal pumps; some listings specify 50–100 psi for specific configurations[1][4][5]
• Industrial fluids, oils, waste oils, and fluids with solids up to 1/8 inch (3.2 mm) in size[1][4][5]
• UL listed for certain configurations[4][5]
• Stall-free, low-pulsation air valve for smooth operation
• Robust aluminum construction for durability
• Capable of handling solids up to 1/8 inch (3.2 mm)
• Easy maintenance with accessible components
• Reliable performance in continuous and intermittent duty cycles
• Maximum cycle rate: 280 CPM[1][3][4]

Applications:
Industrial fluid transfer, oil and waste oil handling, fluid reclamation, circulation systems, and applications requiring reliable, low-maintenance pumping of fluids with suspended solids[1][4][5]

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment of inlet and outlet connections (1 in. NPT standard for many models)
• Follow recommended air pressure operating range (typically 20–100 psi, depending on configuration)
• Check for correct installation of diaphragms, seats, and balls as per manufacturer guidelines
• Regularly inspect and maintain diaphragms and seals for wear and tear
• Use appropriate wall-mount or floor-mount brackets as required for stability and safety
• Periodically check and replace diaphragms and seals as needed
• Monitor air consumption and cycle rate for signs of wear or inefficiency
• Keep pump and surrounding area clean to prevent contamination
• Consult the equipment manual for specific maintenance intervals and procedures
