II. Product Details (PRODUCT DETAILS)

1. Fast Flow & High Pressure: Efficiency for Heavy-Duty Use

• 2 L/min Flow Rate: Outperforms standard manual grease pumps (typically 1-1.5 L/min), cutting lubrication time by 25%. For example, filling a 10L machinery grease tank takes only 5 minutes, ideal for busy workshops or construction sites.
• 2000-3000psi Transmission Pressure: Ensures medium-to-high viscosity grease is pushed into tight machinery gaps (e.g., bearing races, hydraulic joints). This prevents machinery wear caused by insufficient lubrication.

2. Flexible Capacity & Mobility: Adapt to Diverse Needs

• 8L/12L/16L Options: The 8L model fits small-scale use (daily lubrication of 5-8 machines), 12L for medium facilities (8-15 machines), and 16L for large plants (15+ machines). This eliminates frequent refilling and boosts productivity.
• Compact & Lightweight Design: At 56×36.5×17cm and 9kg, the pump is easy to transport—one person can carry it to lubricate scattered equipment (e.g., construction vehicles, port cranes) without heavy tools.

3. Safety & Durability: Reliability for Long-Term Use

• Built-In Safety Features: The pressure relief valve automatically releases excess pressure (above 3000psi), avoiding hose bursts or pump damage. Leak-proof piston seals reduce grease waste by 15% compared to standard pumps.
• Tough Construction: The high-impact plastic body resists bumps and drops in industrial environments, while the oil-resistant rubber hose withstands harsh grease and frequent bending. This ensures a service life of 5+ years with regular maintenance.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Construction Site Excavator Lubrication

1. Setup: Choose YD52-005B (12L capacity) to avoid refilling mid-task; carry the pump to each excavator;
   
   
   2. Lubrication: Connect the 2m hose to the excavator’s grease inlet; use the manual piston to dispense grease at 2 L/min—8L per excavator takes 4 minutes;
   
   
   3. Efficiency: 12 excavators lubricated in 48 minutes; no power needed (works anywhere on-site);
   
   
   4. Mobility: Lightweight design allows easy transport between 3 construction zones.
   
   
   Effect: Fast flow meets daily demands; mobility fits scattered equipment; no power reliance suits site conditions.

2. Manufacturing Plant Conveyor Belt Maintenance

1. Setup: Deploy YD52-005C (16L capacity) near the conveyor belt area; connect the hose to the bearing lubrication ports;
   
   
   2. Lubrication: Dispense 5L grease per conveyor belt in 2.5 minutes (2 L/min flow); the high pressure ensures grease reaches deep into bearings;
   
   
   3. Safety: Pressure relief valve prevents over-lubrication, protecting belt bearings from damage;
   
   
   4. Productivity: 20 conveyor belts serviced in 50 minutes—minimal downtime for production.
   
   
   Effect: Fast flow reduces maintenance time; high pressure ensures thorough lubrication; safety features protect equipment.

3. Port Crane Joint Lubrication

1. Setup: Load YD52-005C (16L capacity) onto a handcart; transport to each crane;
   
   
   2. Lubrication: Use the 2m flexible hose to reach high joints; dispense 12L grease in 6 minutes per crane;
   
   
   3. Durability: The pump’s tough body withstands outdoor rain and dust; the oil-resistant hose resists grease degradation;
   
   
   4. Convenience: Manual operation works without power—no need for extension cords or generators.
   
   
   Effect: Outdoor-friendly design ensures reliability; large capacity fits monthly needs; mobility suits port layouts.
