The GRACO 647124 is an air-operated double diaphragm pump featuring an aluminum center section and Buna-N (nitrile) seats, balls, and diaphragms. It is designed for reliable transfer of fluids in industrial applications, especially where compatibility with natural gas or compressed air is required, and is certified for use in Canada (CSA).

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1" BSPT
• Aluminum center section, Buna-N seats, balls, and diaphragms
• Up to 49 gpm (185 lpm) for similar Husky 1050 models; not explicitly specified for this configuration
• Designed for use with natural gas or compressed air; suitable for low, mid, and high viscosity fluids including glycol and general chemicals
• CSA certified (for use in Canada)
• Stall-free low pulsation air valve for smooth and rapid changeover
• Reliable and robust construction for demanding environments
• Easy maintenance and serviceability
• Suitable for remote oil and gas fields and offshore rigs

Applications:
Ideal for glycol circulation systems, general chemical transfer, and fluid circulation in upstream and midstream oil and gas applications. Suitable for use in environments with limited traditional energy resources.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty and certification compliance.
• Ensure proper alignment of inlet and outlet connections (1" BSPT)
• Verify compatibility of fluid with Buna-N materials
• Follow local and industry safety standards during installation
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
• Periodically check for leaks and proper operation
• Replace worn or damaged Buna-N components to maintain pump integrity
• Consult the equipment manual for specific maintenance intervals and procedures
