The GRACO 650003 HUSKY PUMP, 1050P-E, PP/PT/PO/4A is an air-operated double diaphragm pump designed for industrial fluid transfer. It features a polypropylene (PP) body with PTFE (Teflon) balls and is intended for reliable, low-maintenance pumping of a wide range of fluids, including those with small solids, in demanding environments[2][3][5].

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050P-E
• Polypropylene (PP) body, PTFE (Teflon) balls, TPE (Hytrel) seat material
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 100–125 psi (7–8.6 bar, 0.7–0.86 MPa) depending on configuration
• Industrial fluids, including those with solids up to 1/8 in (3.2 mm)
• UL listed
• Stall-free low pulsation air valve for smooth, rapid changeover
• Bolted design for even sealing and easy maintenance
• Reliable, robust construction for heavy-duty use
• Suitable for dry or wet suction lift (up to 16 ft dry, 29 ft wet)
• Handles solids up to 1/8 in (3.2 mm)

Applications:
Ideal for transferring a wide range of industrial fluids, including those with small solids, in sectors such as mining, agriculture, chemical processing, and general manufacturing[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 of pump and piping to avoid stress on connections
• Use appropriate thread sealant for air and fluid connections
• Check for leaks after installation and during initial operation
• Follow manufacturer’s guidelines for air supply pressure and flow rate
• Regularly inspect diaphragms, balls, and seals for wear and replace as needed
