The GRACO 77X012 is a heavy-duty automatic lubrication system component designed for use in construction and mining equipment. It features a robust 24 VDC HP pump and a vent valve with a tube-in-tube system, intended for reservoirs of 90 or 120 lb (41 or 55 kg). The kit is engineered to provide continuous, reliable lubricant replenishment to critical pivot points, helping to flush contaminants and reduce component failures.

Key Features:

• Electric automatic lubrication system injector kit
• Custom Tank Injector Kit for 90 or 120 lb (41 or 55 kg) reservoir
• HP models: up to 5000 psi (34.47 MPa, 344 bar)
• Designed for use with heavy-duty construction and mining equipment requiring automatic lubrication
• GRACO Advantage Drive™ heavy-duty gear drive, lubed for life
• Tube-in-tube vent and fill path for easy conversion of drum to injector system
• Vent valve mounted directly to pump—no brackets or extra hoses/pipes
• Motor control for speed and AMP adjustment
• Cold weather performance down to -40°C
• Efficient seal replacement
• Continuous lube replenishment for reduced component failures

Applications:
Used in heavy-duty construction and mining equipment for automatic, continuous lubrication of critical pivot points to flush contaminants and prevent expensive component failures.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Convert standard drum to injector pump station in minutes using the tube-in-tube system
• Vent valve is mounted directly to the pump, eliminating the need for extra brackets or hoses
• Ensure proper electrical connection (24 VDC, 18–32 VDC input range)
• Follow manufacturer guidelines for cold weather operation and maintenance
• Regularly inspect and replace seals as needed for efficient operation
