The GRACO 562859 is a mechanical pump assembly designed for automatic lubrication systems. It is constructed for durability and reliability, intended to be powered by machine motion for dispensing lubricants in industrial machinery. The pump is typically made from robust materials suitable for industrial environments, though specific material is not specified in available sources.

Key Features:

• Mechanical pump
• RMLS-50
• Robust, compact design for industrial use
• Output ranges from 0.020 to 0.050 cu. in. per stroke
• Designed for integration with GRACO automatic lubrication systems and machinery with available mechanical motion
• Compact and simple design
• Direct mechanical action to pump piston
• Reliable for automatic lubrication
• Ease of maintenance (not detailed, but typical for mechanical pumps)

Applications:
Automatic lubrication of machinery where machine motion can be used as the power source for the pump, suitable for industrial, mining, and agricultural equipment

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system
• Ensure proper alignment with machine motion source
• Follow manufacturer guidelines for mounting and connection
• Regularly inspect for wear and proper lubrication
