SureFire II Lubricator – SFX2PBSNNNDXD

The Bijur Delimon SureFire II Lubricator (SFX2PBSNNNDXD) is a compact, electric, motor-driven lubrication pump engineered for single-line positive displacement injector (PDI) systems. This configuration is designed for applications requiring reliable, repeatable oil or fluid grease delivery with external control via PLC or machine control.

What This Configuration Means

The part number SFX2PBSNNNDXD defines a SureFire II lubricator with the following configuration:

• 2-liter reservoir capacity
• PDI (Positive Displacement Injector) distribution system
• Plastic (Luran) reservoir
• Standard lubricant viscosity range
• Standard fill cap with integrated strainer
• No integral controller (terminal block operation)
• Three-phase motor configuration
• Low-level monitoring for fail-safe operation

How the SureFire II PDI System Operates

During operation, the internal gear pump draws lubricant from the reservoir and pressurizes the main supply line. This pressure forces all connected positive displacement injectors (PDIs) to discharge their preset lubricant volumes to individual lubrication points.

Once all injectors have completed their discharge, system pressure continues to rise until the pressure switch setting is reached. At this point, the control system can stop the motor. The resulting pressure differential activates the internal quick dump valve, relieving pressure back into the reservoir and resetting the system for the next lubrication cycle.

Typical Applications

• CNC machining centers and lathes
• Machine tools with centralized lubrication points
• Production equipment requiring precise oil or fluid grease delivery
• Systems controlled by PLCs or machine controllers
• Applications with up to 100 lubrication points

Key Performance Characteristics

• Electric motor-driven gear pump
• Maximum output pressure (PDI): 450 psi (31 bar)
• Maximum output volume: 250 cc/min
• Supports oil and fluid greases (PDI systems)
• Operating temperature range: 40°F to 105°F (5°C to 40°C)
• IP54 enclosure rating

Lubricant Compatibility

This SureFire II configuration is suitable for:

• Industrial oils with viscosities from 20 to 1500 cSt
• Fluid greases (PDI only) up to NLGI 000 / 00, pending application review

When to Use This Model

• When lubrication timing and logic are handled externally
• When precise, metered delivery to multiple points is required
• When a three-phase power supply is available
• When a compact, centralized lubrication pump is needed

When to Select a Different Configuration

• If integrated timing or fault monitoring is required
• If resistance fitting (SLR) systems are used instead of injectors
• If a different reservoir capacity or voltage is needed
