The GRACO 188078 Rod, Displacement is a precision-engineered component designed for use within GRACO hydraulic reciprocator and pump assemblies. It is typically constructed from durable metal to withstand the mechanical stresses of reciprocating motion. Its primary function is to facilitate the displacement of hydraulic fluid or other media within GRACO equipment, ensuring smooth and reliable operation of the pump system.

Key Features:

• Displacement rod
• Compatible with GRACO hydraulic reciprocator and pump assemblies (e.g., Dyna-Star series)
• Engineered for durability and reliability in high-duty cycle applications
• Precision fit for smooth reciprocating motion
• Designed for ease of maintenance and replacement

Applications:
Used in GRACO hydraulic reciprocator and pump systems for fluid displacement in industrial, mining, and agricultural lubrication and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise system reliability and void warranties.
• Refer to the equipment manual for specific installation instructions and torque specifications
• Ensure proper alignment and fit during installation
• Use recommended tools and follow torque guidelines (e.g., torque to 42–45 in-lb for certain fasteners as per manual)
• Apply appropriate primer and thread locker as specified in the manual
• Regularly inspect the rod for wear or damage
• Replace as part of scheduled maintenance or when performance issues arise
• Use only compatible replacement parts and lubricants
