Applications:
Used in industrial hydraulic systems for driving proportioning pumps, particularly in lubrication and maintenance applications where precise and reliable hydraulic actuation is required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the hydraulic system.
• Read all warnings and instructions in the manual before installation
• Ensure the system is depressurized before installation or maintenance
• Use only compatible hydraulic fluids and fittings
• Follow all safety procedures outlined in the manual
• Regularly inspect for leaks and wear
• Monitor hydraulic fluid levels and quality
• Replace worn or damaged components promptly
• Keep the actuator clean and free from debris
