The GRACO 222802 is a lower piston assembly with a carbide seat, designed for use in the Dura-Flo 2400 (580 cc) pump. It is engineered for durability and precise sealing, ensuring reliable operation in high-pressure fluid handling systems. The carbide seat enhances wear resistance and longevity, making it suitable for demanding industrial applications.

Key Features:

• Lower Piston, Carbide Seat
• Dura-Flo 2400 (580 cc)
• Up to 24 MPa (235 bar, 3400 psi) for Dura-Flo 2400 lowers (varies by configuration; check specific model for exact rating)
• Dura-Flo 2400 (580 cc) pumps and compatible GRACO fluid handling systems
• Carbide seat for enhanced wear resistance and durability
• Engineered for reliable sealing and long service life
• Designed for easy maintenance and replacement as part of the lower assembly

Applications:
Used in industrial fluid handling, lubrication, and spray systems where high-pressure, reliable piston operation is required. Suitable for mining, agriculture, manufacturing, and other heavy-duty applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment. Non-genuine parts may compromise system integrity and void warranties.
• Lubricate piston packings before installation
• Ensure proper alignment of the piston and rod during assembly
• Torque components to manufacturer specifications (e.g., 459–481 N.m for rod assembly)
• Use an arbor press for safe and precise installation of the rod and piston into the cylinder
• Inspect seals and o-rings for wear and replace as needed
• Regularly inspect piston and seat for wear or damage
• Replace worn or damaged components promptly
• Follow GRACO’s recommended maintenance schedule for the Dura-Flo 2400 pump
