• Operating temperature range: -20°F to 120°F (-29°C to 49°C) for standard operation; optional heating extends range for specialized applications
• Operating speed: 3 to 36 rpm
• Reliable, easy-to-maintain design
• Provisions for flange-mounted auto-fill and low-level alarms

Applications:
Industrial lubrication for heavy machinery, mining, manufacturing, and other sectors requiring high-pressure, reliable lubrication delivery.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems.
• Ensure proper alignment and secure mounting of the lubricator
• Connect steam or electric heating as required for the application
• Verify compatibility of lubricant viscosity and operating temperature
• Regularly inspect and maintain seals, valves, and reservoir for optimal performance
• Follow manufacturer guidelines for installation and maintenance to maximize equipment lifespan
