The GRACO MBG0AA is a robust automatic lubrication pump designed for heavy-duty industrial applications. It is constructed from durable materials to withstand harsh environments and is intended for use within GRACO’s MBL Box Lubricator systems to deliver consistent lubrication to critical machinery components.

Key Features:

• Automatic lubrication pump
• MBG0AA (MBL Lubricator, GBL)
• Heavy-duty, engineered for durability and extreme conditions
• Compatible with GRACO MBL Box Lubricator systems; designed for use with oil or grease (specific models may vary)
• Engineered for durability and heavy usage
• Precision stroke length (~0.05") to eliminate vapor locks and improve flow
• Multiple reservoir capacities (4 to 40 pints) and pump configurations (1 to 24 pumps)
• Electric heater options available for larger reservoirs (not for 4 pint size)
• Thermostat-controlled heating for consistent oil temperature
• Blank cover assemblies included for unused pump positions

Applications:
Used in industrial environments requiring reliable, automatic lubrication of machinery, including mining, manufacturing, and agriculture. Suitable for both oil and grease applications depending on configuration.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure heater elements are completely submerged in oil at all times if using electric heaters
• Follow wiring schematics for heater options as specified in the manual
• Adjust thermostat to break contact at desired temperature (max recommended setting: 1500°F/660°C for heater, but typical operating range is lower)
• Use appropriate number of heaters for reservoir size (1 for 6–12 pints, 2 for 16–24 pints, 3 for 32–40 pints)
• Regularly inspect and maintain pump and reservoir for optimal performance
