The GRACO 26D862 appears to be an air-operated piston oil pump, commonly used for transferring oil and similar fluids in industrial lubrication systems. While the exact material is not specified for this part number, typical GRACO piston oil pumps are constructed from zinc-plated carbon steel, aluminum, nitrile, polyurethane, and nickel-plated aluminum components. These pumps are designed for reliable, high-pressure oil transfer in demanding environments.

Key Features:

• Air Operated Piston Oil Pump
• Reliable air-operated piston design
• Easy maintenance and serviceability
• Robust construction for industrial use
• Low noise operation (typical: 72.9–82 dB(a))
• Quick-disconnect coupler for easy maintenance
• Replaceable seat and floating priming plate for improved serviceability

Applications:
Industrial oil transfer, lubrication systems, bulk fuel storage and dispensing, and other applications requiring reliable, high-pressure fluid transfer.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise system integrity and void warranties.
• Ensure proper alignment and secure mounting of the pump
• Use recommended fittings and hoses for oil transfer
• Follow manufacturer guidelines for air supply pressure and flow
• Regularly inspect and maintain seals and packings for leak prevention
• Consult the equipment manual for specific installation instructions
• Perform routine checks on seals, packings, and moving parts
• Replace worn components with genuine GRACO parts
• Keep the pump clean and free from debris
• Monitor noise and vibration for early detection of issues
