The GRACO 77X202 is an electric injector module designed for automatic lubrication systems. It features a 24 VDC pump, tube-in-tube design, vent valve, low-level sensor, cover, tank, and auto-fill shutoff (AFSO) for a 60 lb (27 kg) reservoir. It is engineered for heavy-duty applications, supplying lubricant and flushing contaminants from critical pivot points in construction and mining equipment. The module is constructed with robust materials for durability and reliability in demanding environments.

Key Features:

• Electric injector module with pump
• 77X202, 60 lb (27 kg) reservoir
• Robust steel and engineered plastics for durability
• Maximum working pressure: 3500 psi (24.1 MPa, 241 bar); Maximum refilling inlet pressure: 5000 psi (34 MPa, 344.7 bar)
• For use with single line parallel automatic lubrication systems; not approved for use in European explosive atmosphere locations
• Tube-in-tube design for efficient lubrication
• Vent valve for easy venting and filling
• Low-level sensor for reservoir monitoring

• Easy maintenance and reliable performance
• Built-in pressure relief for safety

Applications:
Heavy-duty construction and mining equipment requiring continuous, automatic lubrication to reduce component wear and prevent failures.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Read all warnings and instructions in the Dyna-Star HP and HF Pump instruction manual and related component manuals before installation.
• Ensure proper wiring and connection of the low-level sensor and other components as per the manual.
• Regularly inspect and maintain the system to ensure continuous operation and prevent contamination.
• Use only recommended lubricants and follow GRACO’s maintenance guidelines.
• Save all instruction manuals for future reference.
• Contact a GRACO specialist for detailed installation and compatibility information.
• Perform preventative maintenance to ensure peak performance and longevity.
