II. Product Details (PRODUCT DETAILS)

1. 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). Ideal for workshops maintaining cars, small tractors, or medium-sized industrial machinery.
• Low Maintenance & Long Life: The simplified internal structure reduces wear, cutting maintenance frequency by 40% compared to generic air-operated pumps. It works seamlessly with most lubrication systems and grease drums, eliminating compatibility issues.

2. YD52-008 (65:1 Compression Ratio): Power for Ultra-High Viscosity

• 500 Bar Max Flow Pressure: Outperforms the YD52-007 by handling ultra-high viscosity grease (up to SAE300)—e.g., industrial gearbox grease or heavy construction machinery lubricants that clog standard pumps.
• Consistent Performance: Despite the higher compression ratio, it maintains the same 120 L/Min air consumption and 800g/Min relative capacity as the YD52-007, ensuring efficient transfer without extra air supply demands.

3. Universal Advantages for Both Models

• Flexible Suction Tubes: Multiple tube lengths (410mm-940mm) fit small (20-60L) and large (100-200L) grease drums, minimizing residual grease (≤200g per drum) and reducing waste.
• Easy Integration: F1/4"G air inlet and M1/4"G oil outlet fit standard hoses and lubrication kits, allowing quick setup without custom adapters. The 30mm suction tube reaches drum bottoms, ensuring maximum grease utilization.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Automotive Workshop Routine Lubrication (YD52-007, 410mm Tube)

1. Setup: Attach YD52-007 (410mm tube) to a 20L drum; connect F1/4"G air inlet to the shop’s air compressor (8 Bar); attach M1/4"G outlet to a lubrication hose;
   
   
   2. Lubrication: Transfer 200g grease per car in ~15 seconds (800g/Min capacity); the 410mm tube reaches the drum bottom;
   
   
   3. Efficiency: 25 cars serviced in ~6 minutes; no maintenance needed for 2 weeks of daily use;
   
   
   4. Cost-Saving: Residual grease ≤200g per drum, reducing waste by 15% vs. manual pumps.
   
   
   Effect: Low maintenance fits busy workshops; 400 Bar pressure handles engine grease.

2. Construction Site Heavy Machinery Greasing (YD52-008, 940mm Tube)

1. Setup: Use YD52-008 (940mm tube) with a 200L drum; connect to a portable air compressor (8 Bar); extend the lubrication hose to 10m;
   
   
   2. Greasing: Transfer 5kg grease per excavator in ~6.25 minutes (800g/Min); 500 Bar pressure pushes SAE300 grease into hydraulic joints;
   
   
   3. Durability: The pump withstands site dust/rain; no performance drop after weekly use;
   
   
   4. Mobility: Portable air compressor and flexible hose allow greasing in different construction zones.
   
   
   Effect: 65:1 ratio handles ultra-high viscosity; long tube fits large drums.

3. Industrial Plant Gearbox Maintenance (YD52-007, 730mm Tube)

1. Setup: Deploy YD52-007 (730mm tube) with a 100L drum; connect to the plant’s air supply; integrate with the existing lubrication kit via M1/4"G outlet;
   
   
   2. Maintenance: Transfer 1.5kg grease per gearbox in ~1.875 minutes; 400 Bar pressure ensures grease reaches deep gear teeth;
   
   
   3. Integration: Works seamlessly with the plant’s lubrication system, no extra adapters needed;
   
   
   4. Reliability: Runs for 8 hours monthly without maintenance, reducing downtime.
   
   
   Effect: Broad compatibility fits plant systems; long transfer distance optimizes workflow.
