Description
SureFire II Lubricator – SFX2PBLNNNAXB
The Bijur Delimon SureFire II Lubricator (SFX2PBLNNNAXB) is an electrically driven automatic lubrication pump designed for centralized lubrication systems using positive displacement injectors (PDI). This model is configured for applications requiring reliable light oil lubrication to multiple machine points from a single compact unit.
What This Lubricator Is Used For
This SureFire II configuration is commonly installed on CNC machining centers, lathes, milling machines, grinders, and other automated industrial equipment where consistent oil delivery is essential. It supports centralized lubrication networks supplying guideways, ball screws, linear bearings, and other critical wear surfaces while the machine is operating.
How the Lubrication Cycle Works
During a lubrication cycle, the internal motor-driven gear pump draws light oil from the reservoir and pressurizes the main supply line. As pressure increases, each connected PDI injector dispenses a fixed, metered volume of lubricant to its assigned lubrication point.
After all injectors have discharged, system pressure rises to a preset level. The pump then unloads and a quick-dump valve relieves pressure back to the reservoir, allowing injectors to reset and prepare for the next lubrication cycle.
Configuration Overview
- Distribution Type: Positive Displacement Injectors (PDI)
- Lubricant Type: Light oil (5–40 cSt)
- Reservoir Capacity: 2 liter
- Reservoir Construction: Plastic
- Control Interface: Terminal block with momentary run capability
- Electrical Supply: Single-phase AC
Key Advantages
- Provides accurate oil lubrication to multiple points from one centralized pump
- Supports clean, low-viscosity lubrication strategies
- Reduces manual lubrication and maintenance variability
- Compact design integrates easily into machine enclosures
- Expandable system architecture using PDI injectors
Typical Applications
- CNC machining and turning centers
- High-speed production equipment
- Automated manufacturing and assembly lines
- Industrial machinery requiring centralized oil lubrication
Application Guidance
The SFX2PBLNNNAXB is intended for properly designed PDI lubrication systems using approved light oil lubricants within recommended viscosity ranges. Lubrication timing and motor control are typically handled by the host machine or external PLC. Correct injector sizing and system layout are essential for consistent performance.
