Applications

Construction & Earthmoving Machinery: Automated multi-point greasing for excavators, wheel loaders, and mobile cranes operating in severe dirt and moisture.

Mining & Quarrying Equipment: Continuous protection for jaw crushers, vibrating screens, conveyor pivot points, and underground mining rigs.

Wind Turbines: Precise, automated pitch and yaw bearing lubrication operating autonomously in remote high-altitude towers.

Port Cranes & Material Handling: Reliable wear protection for heavy-duty slewing rings, spreaders, and high-load boom pivots.

Plastic Injection Molding & Presses: Centralized lubrication for toggle mechanisms, guide pillars, and high-tonnage clamping units.

Control System & Automation

Smart Cycle Verification: Integrated electronic proximity switches or magnetic cycle pins monitor exact piston movement, confirming that a full lubrication cycle has successfully executed.

Instant Fault Detection: If a single line or bearing blocks, the frozen piston stops the monitoring switch from toggling, instantly signaling an alarm via your PLC or stopping the machine to prevent damage.

Programmable Timers: Fully adjustable pause and run times optimized to prevent over-lubrication while ensuring optimal grease film retention on high-friction surfaces.

Our Service

Pre-Startup Line Flushing: Mandatory purging of all main and secondary lines using clean oil or grease to flush out installation debris.

Air Bleeding Protocol: Step-by-step priming instructions to completely evacuate trapped air pockets from high-pressure lines before live operation.

System Pressure Testing: Recommended commissioning checks to verify relief valve settings and ensure zero leakage across all progressive fittings.

Packaging & Logistics

Inner Packaging: Each batch of fittings is counted, oil-coated for temporary anti-rust protection, and sealed in heavy-duty polyethylene bags with clear label identification (Part Number, Batch Code, Quantity).

Outer Packaging: Packed in double-walled corrugated export cartons, then palletized and shrink-wrapped for sea or air freight transit. Custom barcode labeling and private-label packaging are available for global distributors.

Shipping Terms: EXW, FOB, CIF, DDP via air express, air cargo, or ocean container shipping. Real-time tracking and full customs documentation (Certificate of Origin, Material Test Report) are provided with every shipment.

FAQ

Q: What is a Series Progressive Lubrication System?

A: It is an automated centralized lubrication network that uses a single pump and a series of interconnected progressive divider blocks to deliver metered amounts of grease or oil sequentially to multiple friction points in a continuous loop.

Q: What happens if a single lubrication point becomes blocked in a progressive system?

A: Because the internal pistons operate in a strict dependent sequence, a blockage at any single bearing point will instantly freeze the entire divider block cycle. This triggers an integrated cycle switch or pressure alarm, notifying operators immediately before damage occurs.

Q: How do I verify that the system is working properly?

A: Systems are typically equipped with electronic cycle switches (proximity or magnetic sensors) or visual indicator pins on the divider blocks. Every successful full cycle sends a confirmation signal to your PLC or control panel.

Q: Can I adjust the amount of grease delivered to individual bearings?

A: Yes. Progressive divider blocks are assembled using interchangeable metering segments of different volumetric sizes, allowing you to customize the exact discharge volume delivered to each specific bearing based on its load.

Q: What types of lubricants are compatible with progressive systems?

A: Our systems are engineered to handle standard mineral oils, synthetic lubricants, and heavy greases up to NLGI Grade 2. (Consult our engineering team for high-viscosity NLGI Grade 3 applications).

Q: Are progressive systems suitable for mobile machinery like excavators?

A: Absolutely. We offer rugged 12V and 24V DC electric pump packages as well as hydraulic-driven units specifically built to withstand the high vibration, shock loads, and weather exposure typical of mobile construction and mining equipment.
