The GRACO 133956 G5™ Standard Pump Assembly is a robust, quintuplex lubrication pump designed for heavy-duty applications, particularly in harsh environments such as hydraulic fracturing (fracking) operations. It features a high-impact, UV-resistant reservoir and is engineered to deliver reliable, long-lasting performance. The pump is intended for use in automatic lubrication systems to extend the life of plunger packing seals and other critical components in oil and gas equipment.

Key Features:

• Quintuplex lubrication pump
• G5™ Standard Pump Assembly, 24 VDC, 4 Liter
• High-impact, UV-resistant reservoir; robust pump elements
• Adjustable per element per minute: 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 GRACO automatic lubrication systems, especially in oil and gas, mining, and heavy equipment applications
• Five adjustable pump elements for versatile lubrication
• External low level and pressure relief valves
• Reservoir wiper arm to prevent material separation
• Optional auto-fill shutoff (AFSO) for spill prevention
• Robust construction for harsh environments
• Easy installation with standard 5-pin CPC connectors
• Reliable, heavy-duty performance
• Maximum run time: 30 minutes
• Operating temperature: -40°F to 158°F (-40°C to 70°C), depending on lubricant

Applications:
Primarily used in hydraulic fracturing (fracking) operations, oil and gas equipment, and other heavy-duty industrial applications requiring reliable, automatic lubrication of critical components.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the lubrication system. Non-genuine parts may compromise system integrity and safety.
• Ensure the pump is installed according to GRACO guidelines for your specific equipment
• Use appropriate connectors and wiring for 24 VDC power supply
• Install pressure relief valves as required for your application
• Regularly inspect and maintain the reservoir and pump elements
• Consider using the optional auto-fill shutoff (AFSO) to prevent spills and overfilling
• Follow preventative maintenance schedules to maximize equipment life
