The GRACO 134179 is a pump assembly designed for the G5 series, featuring a 4-liter reservoir, auto-fill shutoff (AFSO), and four pressure relief valves (4KPRV). It is constructed for robust industrial use, typically in lubrication systems for heavy-duty equipment. The assembly is engineered to provide reliable, high-pressure lubrication in demanding environments such as mining, oil and gas, and agriculture.

Key Features:

• Pump Assembly
• G5 Series, 4L Reservoir
• High-impact, UV-resistant reservoir; robust industrial-grade components
• Adjustable per pump element: 0.055–0.155 in³/min (with shims)
• Maximum pressure: 4,250 psi (293 bar)
• Designed for use with GRACO G5 series lubrication systems and compatible enclosures
• Five adjustable pump elements for versatile lubrication
• Auto-fill shutoff (AFSO) for automated reservoir management
• Four pressure relief valves (4KPRV) for safety and system protection
• Robust, UV-resistant reservoir for harsh environments
• Easy maintenance and reliable operation
• Suitable for continuous duty in demanding industrial applications

Applications:
Ideal for automatic lubrication systems in mining, oil and gas (including hydraulic fracturing), agriculture, and other heavy industries requiring reliable, high-pressure grease or oil delivery.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the lubrication system.
• Ensure compatibility with existing GRACO G5 series enclosures and controllers
• Follow manufacturer guidelines for wiring and plumbing connections
• Regularly inspect and maintain pump elements and valves for optimal performance
• Use only recommended lubricants and fluids for the system
• Install in a clean, dry environment to prevent contamination
• Check all connections for leaks after installation
• Schedule routine maintenance as per GRACO recommendations
