II. Product Details (PRODUCT DETAILS)

1. 50:1 Pressure Ratio: Power for Thick Grease

• 25-50 Mpa Working Pressure: The 50:1 pressure ratio generates sufficient force to push high-viscosity greases (e.g., SAE240 gear grease, synthetic hydraulic grease) into narrow machinery gaps—something standard manual pumps (≤30 Mpa) cannot achieve. This ensures thorough lubrication of heavy-duty components like excavator hydraulic joints or port crane bearings.
• Smooth Air Motor Action: The unique air motor eliminates "stuttering" during pumping, maintaining a steady 0-0.5 L/min flow. This avoids uneven lubrication and reduces machinery wear caused by under-greasing.

2. Flexible Capacity & Wheel-Mounted Mobility

• 12L/20L/30L Options: The 12L model fits small workshops (daily lubrication of 5-8 machines), 20L for medium facilities (8-15 machines), and 30L for large plants/construction sites (15+ machines). This minimizes frequent refilling and boosts productivity.
• Wheel-Mounted Tank: Unlike heavy fixed grease systems, the wheel-mounted design allows easy movement—one person can roll the pump to scattered machinery (e.g., construction vehicles, factory conveyors) without lifting, saving 60% of labor time.

3. Durable Build & Safety

• Seamless Pressed Tank: The tank’s seamless construction ensures the follower plate adheres tightly to the grease surface, preventing air ingress and grease contamination. This extends grease shelf life and reduces waste by 20% compared to tanks with seams.
• High-Pressure Hose & Safety Valve: The 4m hose withstands 25-50 Mpa pressure without bursting, while the pressure relief valve automatically releases excess pressure, protecting operators and equipment from harm.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Construction Site Excavator Hydraulic Greasing

1. Setup: Choose YD52-006C (30L capacity) to service 2 excavators per tank; connect the pump to a portable air compressor (0.5-0.7 Mpa);
   
   
   2. Greasing: Roll the wheel-mounted pump to each excavator; use the 4m hose to reach hydraulic joints; the 50:1 ratio pushes thick grease into components—15L per excavator takes ~30 minutes;
   
   
   3. Efficiency: 8 excavators serviced in 4 hours; no manual carrying (saves labor);
   
   
   4. Reliability: Smooth air motor action ensures no pumping interruptions.
   
   
   Effect: High pressure handles thick grease; wheel design fits site mobility needs.

2. Manufacturing Plant Heavy Machinery Maintenance

1. Setup: Deploy YD52-006B (20L capacity) near the gearbox area; connect to the factory’s compressed air supply;
   
   
   2. Greasing: Dispense 8L grease per gearbox in ~16 minutes (0.5 L/min flow); the 4m hose reaches gearbox lubrication ports without moving the pump;
   
   
   3. Safety: Pressure relief valve prevents over-greasing, protecting gearbox seals;
   
   
   4. Productivity: 12 gearboxes serviced in 3.2 hours—minimal impact on production.
   
   
   Effect: Consistent flow ensures thorough lubrication; high pressure suits SAE200 grease.

3. Port Crane Joint Lubrication

1. Setup: Use YD52-006C (30L capacity) with a portable air compressor; roll the pump to crane bases;
   
   
   2. Greasing: Extend the 4m hose to reach high joints; the 50:1 ratio pushes synthetic grease into joints—20L per crane takes ~40 minutes;
   
   
   3. Durability: Seamless tank resists outdoor dust/rain; wheel design works on port concrete floors;
   
   
   4. Convenience: No manual lifting—one technician can complete lubrication alone.
   
   
   Effect: Long hose reaches high joints; high pressure handles synthetic grease; outdoor-friendly build ensures reliability.
