The GRACO LM4333 Lubemaster Pump is an electric piston pump designed for reliable lubrication of machinery. It is constructed with robust materials for industrial environments and is intended to efficiently pump grease or oil to various types of equipment, ensuring consistent lubrication and reducing maintenance downtime.

Key Features:

• Electric piston pump
• LM4333
• Hardened steel piston in steel sleeve, modular components
• Designed for use with Trabon Series Flo® divider valves and a wide range of machinery
• 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
• Reliable operation with anti-friction drive bearings
• Modular components for flexibility
• Can be driven by electric motor (gear drive) or rotating/oscillating motion (clutch drive)
• Optional high-pressure and low-level switches for system protection

Applications:
Used for automatic lubrication of all types of machinery in industrial, mining, agricultural, and other heavy-duty environments. Suitable for both grease and oil applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety of the lubrication system.
• Ensure proper mounting and alignment for efficient operation
• Connect to appropriate power supply (230/460V, 3 phase, 60 Hz, 1/2 HP motor for LM4333)
• Verify compatibility with existing divider valves and system controls
• Install optional high-pressure and low-level switches for added protection
• Regularly inspect and maintain modular components for long service life
