Product Details
The YEEDA YD52-007/008 Air-Operated Grease Pump Series solves grease transfer challenges with high compression ratios (50:1/65:1), long-life design, and broad compatibility.
YD52-007 (50:1 Compression Ratio): Reliable for Standard High Viscosity
- 400 Bar Max Flow Pressure: Effortlessly transfers standard high-viscosity grease (up to SAE240) over short or long distances (0.5-10m).
- Low Maintenance & Long Life: Simplified internal structure reduces wear, cutting maintenance frequency by 40% compared to generic pumps.
YD52-008 (65:1 Compression Ratio): Power for Ultra-High Viscosity
- 500 Bar Max Flow Pressure: Handles ultra-high viscosity grease (up to SAE300) for industrial gearbox grease or heavy construction machinery lubricants.
- Consistent Performance: Maintains 120 L/Min air consumption and 800g/Min relative capacity despite higher compression ratio.
Universal Advantages for Both Models
- Flexible Suction Tubes: Multiple lengths (410mm-940mm) fit small (20-60L) and large (100-200L) grease drums, minimizing waste.
- Easy Integration: Standard F1/4"G air inlet and M1/4"G oil outlet fit existing hoses and lubrication kits.
Application Scenarios
Automotive Workshop Routine Lubrication (YD52-007, 410mm Tube)
Scenario: Car repair shop lubricates 25 cars daily using 20L grease drums.
Operation: Transfer 200g grease per car in ~15 seconds; 25 cars serviced in ~6 minutes.
Benefits: Low maintenance fits busy workshops; 400 Bar pressure handles engine grease.
Construction Site Heavy Machinery Greasing (YD52-008, 940mm Tube)
Scenario: Construction site lubricates 8 excavators weekly using 200L drums.
Operation: Transfer 5kg grease per excavator in ~6.25 minutes; 500 Bar pressure pushes SAE300 grease.
Benefits: 65:1 ratio handles ultra-high viscosity; long tube fits large drums.
Industrial Plant Gearbox Maintenance (YD52-007, 730mm Tube)
Scenario: Factory maintains 12 industrial gearboxes monthly using 100L drums.
Operation: Transfer 1.5kg grease per gearbox in ~1.875 minutes; 400 Bar pressure ensures deep penetration.
Benefits: Broad compatibility fits plant systems; long transfer distance optimizes workflow.
Frequently Asked Questions
Q1: YD52-007's flow slows down when transferring SAE240 grease. How to fix?
A1: Check air pressure (ensure 8 Bar), clean suction tube, or warm grease to 25-30℃ to restore flow rate.
Q2: Can YD52-008 be used for grease with viscosity higher than SAE300 (e.g., SAE320)?
A2: No. Exceeding SAE300 limit reduces flow rate by 50% and risks damaging pump components.
Q3: The pump makes loud noise during operation. What's the issue?
A3: Check for air leaks, lubricate air motor monthly, or inspect for loose parts causing vibration.
Q4: How to choose between YD52-007 and YD52-008 for my business?
A4: YD52-007 for standard high-viscosity grease (up to SAE240); YD52-008 for ultra-high viscosity (up to SAE300).
