The GRACO MBD0AL MBL Lubricator, GBL is an automatic lubrication system component designed for reliable, centralized lubrication in industrial environments. It is typically constructed from robust materials suitable for heavy-duty use and is intended to deliver lubricant efficiently to multiple points within machinery or equipment.

Key Features:

• Automatic box lubricator
• Heavy-duty, engineered for durability and extreme conditions
• Compatible with various MBL pump/reservoir combinations; see GRACO documentation for specific compatibility details
• Hazardous area rating: Class I, Group B (for heater options, if equipped)
• Engineered for durability and heavy usage
• Precision stroke length (~0.05") for improved flow and delivery
• Thermostat-controlled electric heater options (not available for 4 pint reservoirs)
• Heater elements must be completely submerged in oil at all times
• Blank cover assemblies included for unused pump positions

Applications:
Centralized lubrication for industrial machinery, mining, agriculture, and other heavy-duty applications

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system
• Follow GRACO installation guidelines for reservoir and pump setup
• Ensure heater elements (if used) are fully submerged in oil
• Adjust thermostat to break contact at desired temperature (max recommended: 1500°F/660°C for heater options)
• Refer to wiring schematics for heater installation if applicable
• Regularly inspect and maintain the lubricator for long service life
