The GRACO 133955 is a robust automatic lubrication pump designed for demanding industrial environments. It features a 4-liter reservoir, low-level indicator, and four pressure relief valves (4K-PRV). The pump is constructed for durability and reliability, intended for use in automatic grease and oil delivery systems within GRACO equipment, particularly suited for harsh applications such as hydraulic fracturing and heavy machinery maintenance.

Key Features:

• Automatic lubrication pump
• G5, 4L
• High-impact, UV-resistant reservoir; robust pump assembly
• Up to 4,250 psi (293 bar)
• Designed for use with GRACO automatic lubrication systems; compatible with various grease types
• Five pump elements for versatile and simple grease operations
• Low-level indicator for reservoir monitoring
• Four pressure relief valves (4K-PRV) for safety and system protection
• Optional auto-fill shutoff (AFSO) available in larger enclosures
• Stirring paddle with wiper arm to prevent material separation
• Flexible power options with CPC-style connectors
• Designed for harsh environments and extended duty cycles
• Easy maintenance and reliable performance

Applications:
Ideal for automatic lubrication of heavy machinery, hydraulic fracturing (fracking) equipment, mining, construction, and agricultural machinery where reliable, continuous lubrication is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the lubrication system.
