The GRACO 648013 HUSKY PUMP, 1050A-E, SS/SS/PO/4A is a stainless steel air-operated double diaphragm pump designed for industrial fluid transfer applications. It is constructed with stainless steel wetted parts and is intended for use in environments requiring corrosion resistance and durability, such as chemical processing, oil and fuel transfer, and other demanding industrial settings[1][2][5].

Key Features:

• Air-operated double diaphragm pump
• 1050A-E, SS/SS/PO/4A
• Stainless steel wetted parts, stainless steel balls, polypropylene diaphragms (PO/4A may refer to specific diaphragm/seat material or configuration; confirm with GRACO for exact details)
• Up to 50 GPM (189 LPM) for Husky 1050 series (exact flow may vary by configuration; confirm for 1050A-E SS/SS/PO/4A)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for Husky 1050 series
• Industrial fluids, chemicals, oils, fuels (compatible with a wide range of industrial fluids; check chemical compatibility for specific applications)
• Stall-free air valve for reliable operation
• One-piece center for longer diaphragm life
• Efficient air consumption (up to 67 SCFM for Husky 1050 series; actual may vary by model)
• Handles solids up to 1/8 in (3.2 mm)
• Corrosion-resistant stainless steel construction
• Easy maintenance and serviceability

Applications:
Industrial fluid transfer, chemical processing, oil and fuel dispensing, waste oil handling, and other applications requiring robust, corrosion-resistant pumping solutions[2][3][5].

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 proper alignment and secure mounting of the pump
• Use appropriate air supply and filtration to prevent contamination
• Follow GRACO’s recommended air and fluid pressure ranges
• Regularly inspect diaphragms, seats, and valves for wear
• Refer to the specific installation manual for detailed instructions
• Perform routine inspections and maintenance as per GRACO guidelines
• Replace diaphragms and seals at recommended intervals
• Keep air and fluid lines clean and free of debris
• Monitor for leaks and unusual noises
