The GRACO MBB0AJ MBL Lubricator, GBL is a modular box lubricator designed for industrial lubrication systems. It is constructed from robust materials suitable for harsh environments and is intended to deliver precise, reliable lubrication to machinery and equipment. The system is engineered for use with mineral oil or synthetic lubricants and supports a wide range of reservoir and pump configurations.

Key Features:

• Box Lubricator
• MBL Lubricator, GBL (SKU:. MBB0AJ); Reservoir capacities: 4 to 40 pints (1.9 to 18.9 L); Supports 1 to 24 pumps
• Heavy-duty, modular design for industrial use
• 3,500 to 7,500 psi (for GBL 7500 pumps)
• Easily interchangeable with other manufacturers’ pumps; compatible with mineral oil or synthetic lubricants
• Hazardous area rating: Class I, Group B (for heater options)
• Modular design allows for custom pump-to-point lubrication systems
• Precision stroke length (~0.05") for improved flow and delivery
• Electric heater options for reservoirs (not available for 4 pint size)
• Thermostat-controlled heating (max recommended setting: 1500°F/660°C for thermostat, but heater range: 60°F to 240°F / 16°C to 116°C)
• Oil level controls and shaft rotation alarm available
• Dependable, easy to maintain, and reliable for continuous duty cycles

Applications:
Industrial lubrication systems for machinery and equipment in sectors such as mining, energy, manufacturing, and agriculture. Suitable for both large-scale and small-scale operations.

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
• Follow wiring schematics for electric heater options
• Use appropriate number of heaters for reservoir size (1 for 6–12 pints, 2 for 16–24 pints, 3 for 32–40 pints)
• Adjust thermostat to break contact at desired temperature
• Regularly check oil level and system integrity for maintenance
