• Electric pump
• LM8511, 20 lb. (9.06 kg) grease metal reservoir
• Hardened steel piston in steel sleeve, metal reservoir
• Designed for use with Trabon Series Flo® divider valves and a wide range of GRACO lubrication systems
• Optional explosion-proof: Class I, Group C and D; Class II, Group E, F, and G (LOH Low Level Option only)
• Adjustable output
• Broad output range
• Simplified construction for ease of maintenance
• Modular components
• Anti-friction drive bearings for improved reliability
• Soft-seat outlet check valve
• Can be driven by electric motor (gear drive) or rotating/oscillating movement (clutch drive)
• Optional high-pressure and low-level switches for system protection

Applications:
Used for automated lubrication of all types of machinery in industrial, mining, agricultural, and manufacturing environments. Suitable for systems requiring reliable, consistent grease or oil delivery.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing GRACO equipment and systems.
• Ensure proper alignment and secure mounting of the pump and reservoir
• Connect to compatible GRACO or Trabon Series Flo® divider valves
• Verify electrical connections and safety features (e.g., high-pressure and low-level switches if installed)
• Regularly inspect and maintain pump components for wear and proper lubrication
• Follow all local safety and electrical codes during installation
