Key Benefits of the Graco G3 Max Lubrication Pump
Automatic Lubrication for Improved Equipment Reliability
The G3 Max Lubrication Pump automatically delivers lubrication to critical components, helping reduce inconsistent manual greasing practices and supporting improved equipment protection.
This helps:
- Extend machinery life
- Reduce component wear
- Improve lubrication consistency
- Reduce maintenance downtime
Features of the G3 Max Lubrication Pump
- Built-in controller with a selectable pump on/pump off timer.
- The low-level indicator provides low warning and shut-down alarm.
- Manual run initiates lube cycle on-demand (a remote option also available).
- Password protection safeguards.
- The pre-lube function can initiate lube cycle on start-up.
- Up to three pressure or cycle switch inputs to ensure proper lubrication cycles.
- Mix/match cycle and pressure switches for custom installations and feedback.
- Machine count input–ideally suited for inconsistently used equipment.
- Fault indication to external alarms.
Advanced Data Management System (DMS™)
Optional DMS™ functionality allows operators to monitor lubrication system performance and lubrication history.
The system supports:
- Lubrication performance tracking
- Data protection and storage.
- USB upload and download capability
- Lubrication cycle analysis
This provides improved visibility into lubrication system operation and maintenance planning.
