The GRACO 15K690 is a stainless steel (SST) guide piston designed for use within GRACO Check-Mate 200 series pumps. It functions as a critical component in the piston assembly, guiding and stabilizing the piston movement during operation to ensure smooth and reliable pump performance.

Key Features:

• Guide Piston
• 2 CM (exact size not further specified; likely refers to a specific pump model or piston diameter)
• Stainless Steel (SST)
• GRACO Check-Mate 200 series pumps
• Stainless steel construction for durability and corrosion resistance
• Precision-machined for reliable piston guidance
• Essential for maintaining pump efficiency and longevity

Applications:
Used in GRACO Check-Mate 200 series pumps for fluid transfer and metering applications in industrial lubrication and maintenance systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal pump performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Refer to the GRACO Check-Mate 200 pump manual for detailed disassembly and reassembly instructions
• Inspect the piston rod and guide for wear or damage before installation
• Use appropriate tools (e.g., vise with soft jaws, wrenches) to avoid damaging components during installation
• Ensure proper torque is applied to all fasteners as specified in the manual
• Lubricate threads and moving parts as recommended
• Regularly inspect the guide piston and associated components for wear or damage
• Replace worn or damaged parts promptly to prevent pump failure
• Follow GRACO’s recommended maintenance schedule
