The GRACO MBB2CN is a robust automatic lubrication pump designed for reliable, long-term performance in industrial environments. It is typically constructed from durable materials suitable for harsh conditions and is intended for use in centralized lubrication systems to deliver oil or grease to multiple lubrication points.

Key Features:

• Automatic lubrication pump
• MBL Box Lubricator, GBL (MBB2CN)
• Compatible with various GRACO MBL Box Lubricator reservoir sizes (4 to 40 pints) and pump combinations
• Precision stroke length (~0.05") for improved flow and delivery
• Designed to avoid vapor locks
• Long piston and rocker life due to design over piston tip
• Multiple heater options for temperature control (not available for 4 pint reservoir)
• Blank cover assemblies included for unused pump positions
• Built for outstanding performance and longevity

Applications:
Used in industrial settings for centralized lubrication of machinery, suitable for mining, agriculture, manufacturing, and other heavy-duty applications.

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 manufacturer wiring schematics for heater installation
• Adjust thermostat to break contact at desired temperature (max recommended setting: 1500°F/660°C for certain components, but confirm for your specific model)
• Use appropriate number of heaters for reservoir size (1 for 6–12 pints, 2 for 16–24 pints, 3 for 32–40 pints)
• Blank cover assemblies should be used on unused pump positions
