The GRACO 562925 HP-50 Lubricator is a high-pressure, single plunger force feed lubricator designed for injecting non-corrosive and non-abrasive oils and synthetic-based lubricants into high-pressure systems. It is constructed for robust industrial use and is intended for lubricating compressor and circulator cylinder walls, heavily loaded bearings, and other moving parts.

Key Features:

• High-pressure lubricator
• HP-50 with 4 pumps
• Industrial-grade, self-lubricated, totally enclosed working parts
• Up to 60,000 psi (4137 bar)
• Non-corrosive and non-abrasive oils and synthetic-based lubricants
• Single plunger force feed design for efficient injection
• Vacuum sight feeds on self-contained pumping units for monitoring output
• Individual pumping units easily removed for service
• All working parts are totally enclosed and self-lubricated
• Highly reliable and suitable for continuous duty cycles

Applications:
Lubricating compressor and circulator cylinder walls, heavily loaded bearings, and other moving parts in industrial machinery.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Follow all safety instructions and warnings provided in the GRACO manual
• Ensure proper grounding and maintenance procedures are observed
• Install in a clean, accessible location for easy service and monitoring
• Regularly inspect and maintain individual pumping units for consistent performance
• Regularly check and adjust feed rates as needed
• Monitor vacuum sight feeds for proper lubricant output
• Service or replace individual pumping units as required
• Keep the lubricator and surrounding area clean to prevent contamination
