The GRACO 133996 is a robust automatic lubrication pump assembly designed for demanding industrial environments. It features a 4-liter reservoir, four pressure relief valves (PRV), and a JIC vent for safe operation. The pump is constructed with high-impact, UV-resistant materials and is intended for reliable grease or oil delivery in harsh conditions, such as hydraulic fracturing (fracking) and pumpjack lubrication.

Key Features:

• Automatic grease/oil pump
• G5, 4L reservoir
• High-impact, UV-resistant reservoir; robust metal and composite components
• Adjustable per pump element: 0.155 in³ (2.54 cm³) [no shim], 0.104 in³ (1.70 cm³) [1 shim], 0.055 in³ (0.90 cm³) [2 shims]
• Maximum pressure: 4,250 psi (293 bar)
• Designed for use with a variety of greases and oils; compatible with GRACO G5 series enclosures and controllers
• Five adjustable pump elements for versatile lubrication
• Robust, UV-resistant reservoir for durability
• Pressure relief valves (PRV) for safety
• JIC vent for safe reservoir venting
• Easy installation with standard connectors
• Designed for harsh environments and demanding applications
• Optional auto-fill shutoff (AFSO) available on some models
• Stirring paddle with wiper arm to prevent material separation

Applications:
Ideal for hydraulic fracturing (fracking) operations, pumpjack lubrication, and other industrial applications requiring reliable, high-pressure grease or oil delivery in harsh environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise system integrity and void warranties.
• Ensure the pump is installed in a clean, dry, and accessible location
• Connect using the provided CPC-style connectors for easy installation
• Verify all pressure relief valves (PRV) and venting are properly configured
• Regularly inspect and maintain the reservoir and pump elements
• Consult the equipment manual for specific installation and maintenance procedures
