The GRACO 563111 is a cylinder assembly for the HP-50 high-pressure lubricator, consisting of a hardened alloy steel cylinder and plunger. It is designed to provide reliable, high-pressure lubrication in industrial applications.

Key Features:

• Cylinder Assembly
• HP-50
• Hardened alloy steel cylinder and plunger, precision-honed and ground
• Up to 50,000 psi (344 MPa, 3,447 bar) for HP-50 lubricator
• For use with GRACO HP-50 high-pressure lubricators
• Precision-ground and fitted plunger for reliability
• Hardened alloy steel construction for durability
• Designed for high-pressure operation
• Long service life with proper maintenance

Applications:
Used in industrial lubrication systems requiring high-pressure delivery, such as mining, manufacturing, and heavy equipment maintenance.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Install with a high-pressure check valve in the discharge line adjacent to the pump discharge connection
• Ensure all seals and gaskets are in good condition before assembly
• Follow manufacturer’s torque specifications for hardware
• Regularly inspect for wear and replace components as needed
