The GRACO 556522 is a thrust disk designed for use in high-pressure lubrication systems, specifically within GRACO HP-50 equipment. It is a critical wear component that helps maintain the integrity and performance of the pump assembly. The material is not explicitly stated, but similar GRACO thrust disks are typically made from durable, wear-resistant materials such as hardened steel or engineered plastics.

Key Features:

• Thrust Disk
• HP-50
• GRACO HP-50 high-pressure lubrication systems
• Designed for high-pressure environments
• Critical for pump longevity and performance
• Engineered for reliability and durability

Applications:
Used in high-pressure lubrication systems for industrial, mining, and agricultural equipment where reliable lubrication is essential.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Always refer to the GRACO equipment manual for specific installation instructions
• Ensure the system is depressurized before replacing the thrust disk
• Inspect for wear and replace as part of regular maintenance to prevent equipment failure
