The GRACO 77X100 is an electric injector module designed for automatic lubrication systems. It features a robust 12-gauge steel reservoir, a high-pressure pump, tube-in-tube design, vent valve, cover, and dip stick. It is intended for reliable, automated delivery of lubricants in demanding industrial environments.

Key Features:

• Electric injector module with pump
• HP 24 VDC, 60 lb (27 kg) reservoir
• 12-gauge steel reservoir, tube-in-tube design
• HP models: 5000 psi (34.47 MPa, 344 bar)
• Designed for use with GRACO automatic lubrication systems; common bolt pattern for easy drop-in replacement
• Adjustable motor control for power input, motor speed, current control, and signal input
• Cavitation-free fill and vent path for easy filling and venting
• Strong 12-gauge steel reservoir
• Alternate fill and vent ports for direct lube delivery to pump bottom
• No external vent hoses or extra internal pipes required
• Easy to convert a standard drum to an injector pump station

Applications:
Automated lubrication in industrial, mining, agricultural, and vehicle service environments where reliable, high-pressure lubricant delivery is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems.
• Ensure proper alignment and secure mounting using the common bolt pattern for easy drop-in replacement
• Connect electrical supply according to specifications (24 VDC, 18–32 VDC input range)
• Follow manufacturer’s instructions for filling and venting to prevent cavitation
• Regularly inspect and maintain the reservoir, pump, and vent valve for optimal operation
