The YEEDA YD52-006A/B/C Pneumatic Grease Pump addresses critical industrial lubrication pain points: "low pressure for thick grease, cumbersome portability, and inconsistent pumping". With "50:1 high pressure ratio + 3 capacity options + wheel-mounted design" as core strengths, it delivers reliable, efficient high-pressure greasing for heavy-duty machinery:
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
Scenario Requirement: A construction site lubricates 8 excavators (each needing 15L high-viscosity hydraulic grease) weekly. The grease is too thick for manual pumps, and excavators are parked in different zones.
Operation Process:
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
Scenario Requirement: A factory maintains 12 industrial gearboxes (each needing 8L gear grease, SAE200) daily. The plant requires consistent, high-pressure greasing to avoid production downtime.
Operation Process:
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;
Scenario Requirement: A port lubricates 6 container cranes (each needing 20L synthetic grease for rotating joints) monthly. Cranes are tall, requiring long-reach greasing, and grease is thick.
Operation Process:
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.
IV. Frequently Asked Questions (FAQ)
Q1: The pump fails to build pressure (working pressure <25 Mpa). How to fix?
A1: Low pressure is usually due to air supply issues or leaks. Solutions: 1) Check Air Pressure: Ensure the air compressor provides 0.5-0.7 Mpa (low air pressure reduces pump output); 2) Inspect Air Motor Connections: Tighten loose air inlet fittings—air leaks reduce pressure generation; 3) Clean Follower Plate: Remove the follower plate and wipe away grease debris (debris prevents proper sealing, causing pressure loss). These steps restore 25-50 Mpa working pressure.
Q2: Can the pump be used for low-viscosity fluids like diesel?
A2: No. The pump is designed for medium-to-high viscosity greases/fluids. Low-viscosity fluids (e.g., diesel) will: 1) Leak through the follower plate (not designed for low-viscosity sealing); 2) Damage the air motor (diesel can corrode motor components); 3) Cause inconsistent flow (low viscosity exceeds the pump’s 0-0.5 L/min control range). Use exclusively for greases and compatible high-viscosity fluids.
Q3: The hose becomes stiff and hard to maneuver. What’s the issue?
A3: Stiff hoses are caused by grease buildup or cold temperatures. Fixes: 1) Flush the Hose: After use, disconnect the hose and flush it with a small amount of low-viscosity oil to remove dried grease; 2) Warm the Hose: In cold weather (<0℃), wrap the hose in a heated blanket for 10 minutes to restore flexibility; 3) Store Properly: Coil the hose loosely when not in use—avoid folding, which causes permanent stiffness.
Q4: How to maintain the pump to extend its service life?
A4: Key maintenance steps: 1) Post-Use Cleaning: Wipe the tank and air motor with a dry cloth; flush the 4m hose to remove residual grease; 2) Lubricate Air Motor: Add 5-10 drops of air tool oil to the air inlet monthly to keep the motor running smoothly; 3) Inspect Follower Plate: Replace worn follower plate seals every 6 months to prevent leaks; 4) Store Correctly: Empty remaining grease before long-term storage; keep the pump in a dry, ventilated area (avoid humidity to prevent tank rust).
