The GRACO 649037 Husky 1050 PP (NPT) Pump is an air-operated double diaphragm pump with a polypropylene (PP) center section, PP seats, CR (polychloroprene) balls, and CO (polychloroprene overmolded) diaphragm. It is designed for reliable, low-maintenance transfer of a wide range of fluids in industrial settings, including chemicals, water, and wastewater, and is suitable for use in environments where corrosion resistance and chemical compatibility are required.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050 PP (NPT), 1" End Flange
• Polypropylene (PP) center section, PP seats, CR (polychloroprene) balls, CO (polychloroprene overmolded) diaphragm, PTFE manifold O-rings
• 50 gpm (189 lpm)
• Maximum fluid pressure: 125 psi (0.86 MPa)
• Suitable for handling antifreeze, detergents, motor oil, hydraulic fluid, water, and wastewater transfer
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Modular air valve for easy service
• Four-bolt joint design for even sealing pressure and leak-free operation
• Multiple ports for installation flexibility
• Up to 5x longer diaphragm life for less maintenance and downtime

Applications:
Industrial fluid transfer, including chemicals, antifreeze, detergents, motor oil, hydraulic fluid, water, and wastewater. Suitable for environments requiring corrosion resistance and chemical compatibility.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment, reducing the risk of leaks and downtime.
• Ensure proper alignment of the pump with piping to avoid stress on connections
• Use appropriate thread sealant for NPT connections
• Check for leaks after installation and during initial operation
• Follow manufacturer-recommended maintenance schedules for diaphragm and valve inspection
• Ensure air supply is clean and dry to prolong pump life
• Regularly inspect diaphragms and valves for wear or damage
• Replace worn parts with genuine GRACO components
• Keep the pump clean and free from debris
• Monitor for unusual noise or vibration, which may indicate maintenance needs
