System Configuration

Pump & Reservoir: Supplies lubricant at the required pressure and flow.

Progressive Distributors: Sequentially distribute measured lubricant volumes to individual outlets.

Monitoring: Pressure switches or sensors monitor system operation and blockage conditions.

Piping: Main and branch lines connect the pump, distributors and lubrication points according to equipment layout.

Configuration: Outlet quantity and distributor capacity can be selected according to the number of lubrication points.

Key Performance Features

High-Pressure Delivery: Operates up to 400 bar working pressure, pumping NLGI 0–2 grease over main-line distances up to 100 meters.

Parallel Point Isolation: Blockage at an individual metering outlet or bearing does not interrupt line pressure or grease flow to remaining distribution blocks.

Calibrated Output Adjustment: Metering block discharge can be mechanically adjusted from 0.5 to 5.0 cm³/stroke per outlet via regulating screws.

Pressure-Driven Changeover: Line switching is triggered by hydraulic or end-of-line differential pressure switches once target threshold is reached, ensuring full pressurization before half-cycle completion.

Industrial Applications

Steel Processing: Continuous casters, hot rolling mills, cooling beds, and furnace conveyors.

Mining & Quarrying: Jaw crushers, vibrating screens, ball mills, and stacker-reclaimers.

Cement Production: Rotary kilns, clinker coolers, roller presses, and raw mills.

Material Handling: Port gantry cranes, container stackers, and bulk ship unloaders.

Paper & Pulp: Wet end press rolls, dryer section bearings, and calendar stacks.

PLC Control & System Integration

Cycle Control: PLC controls lubrication intervals and pump operation.

Cycle Monitoring: Distributor or pressure feedback can verify lubrication cycles.

Fault Detection: Low pressure, low lubricant level and abnormal cycle conditions can trigger alarms.

Machine Interface: Run, fault and status signals can be exchanged with the main control system.

Remote Monitoring: Operating and fault signals can be connected to HMI or supervisory systems.

FAQ

Q: Can your parts directly replace SKF, Lincoln, or Delimon components?

A: Yes. Our pumps, changeover valves, and metering blocks follow standard ISO and BSP/NPT thread profiles for direct drop-in replacement without piping modifications.

Q: What happens if a lubrication point gets clogged?

A: Unlike progressive systems, a clogged outlet or bearing does not block the main supply line or affect grease delivery to other distribution blocks.

Q: What happens if a main line leaks or bursts?

A: The end-of-line pressure switch will fail to reach target pressure within the programmed timeout window, triggering a system fault alarm via the PLC panel.

Q: How does the system handle cold winter operations?

A: For temperatures down to -20°C, pumps can be fitted with electric reservoir heaters, follower plates, and high-pressure pumping elements to prevent grease channeling.

Q: Are hydraulic or electric changeover valves better for my setup?

A: Hydraulic valves switch lines automatically via mechanical differential pressure, while electric solenoid valves switch based on signals sent from end-of-line pressure switches.

Q: Do you offer explosion-proof (ATEX) configurations?

A: Yes. Motors, control panels, solenoids, and pressure switches can be supplied with ATEX/IECEx certifications for underground mining or hazardous chemical zones.

Q: Do you provide 3D CAD files before production?

A: Yes. We supply 2D piping schematics and 3D CAD models (.STEP / .IGS format) based on your point layout for engineering approval before manufacturing.

Q: What is the standard lead time for custom lubrication skids?

A: Standard pumps and metering blocks ship in 7–10 working days. Customized skid packages with special reservoirs or PLC panels require 3–4 weeks.
