The GRACO 904287 is a stainless steel displacement pump designed for high-pressure, high-volume material transfer, commonly used in proportioning and pumping applications within GRACO equipment. It features a robust stainless steel construction and is intended for use with chemically-activated gel systems and other demanding industrial fluids.

Key Features:

• Displacement Pump
• 904287
• Stainless Steel (wetted parts), PTFE, Delrin, Ultra-High Molecular Weight Polyethylene
• Maximum Working Pressure: 1500 psi (10 MPa, 103 bar)
• Compatible with GRACO President® and Hydra-Cat proportioning systems
• Certified and approved for use in proportioning systems (as referenced in GRACO documentation)
• Short stroke, modified intake
• PTFE packings for enhanced durability and chemical resistance
• Chrome-plated and electropolished stainless steel for corrosion resistance
• Reliable performance in high-pressure environments
• Ease of maintenance and replacement of wear parts

Applications:
Used for pumping high volumes of material such as chemically-activated gel systems, grouts, and other industrial fluids. Suitable for applications requiring high pressure and reliability, including grouting, chemical injection, and industrial maintenance.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise system integrity and void warranties.
• Refer to the specific parts list and assembly drawing for Model 904287 in the GRACO manual (pages 12–13 for Model 904287)
• Ensure all wetted parts are compatible with the intended fluid
• Follow recommended maintenance schedules for packings and seals
• Use appropriate tools and torque specifications during assembly
• Regularly inspect and replace wear parts such as packings and seals
• Monitor system pressure and flow to detect early signs of wear or malfunction
• Keep installation area clean and free of contaminants
