The GRACO MBD0AA is a Manzel® MBL Box Lubricator, designed for centralized lubrication systems. It is constructed for robust industrial use and intended to deliver reliable, automatic lubrication to machinery and equipment. The unit is typically made from durable materials suitable for harsh environments, though specific material details are not specified in available documentation. Its primary function is to ensure consistent lubrication across multiple points in industrial settings.

Key Features:

• Automatic box lubricator
• MBL Box Lubricator, GBL
• Compatible with various GRACO MBL pump/reservoir combinations; LH option available only on certain MBL drives (G01, G02, G03, G04, G12)
• Precision stroke length (~0.05") for improved flow and delivery
• Designed to eliminate vapor locks
• Long piston and rocker life due to design that avoids bending and wear
• Available in multiple reservoir capacities (4 to 40 pints)
• Can accommodate 1 to 24 pumps
• Electric heater options for temperature control (not available for 4 pint reservoir)
• Thermostat for temperature regulation (max recommended setting: 1500°F/660°C, but likely a typo; intended for much lower temperatures—see below)
• Heaters must be fully submerged in oil at all times

Applications:
Used in industrial environments requiring centralized, automatic lubrication of machinery and equipment, such as manufacturing plants, mining operations, and agricultural facilities.

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
• Adjust thermostat to break contact at desired temperature (note: maximum recommended setting is likely a typo in documentation; typical thermostat range is 60°F to 240°F/16°C to 116°C for heaters)
• Refer to wiring schematic for heater options and installation
• 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 are included for unused pump positions
• Regularly check oil level and heater operation
• Inspect for leaks or wear on pistons and rockers
• Follow GRACO’s recommended maintenance schedule
