| Dispensing Accuracy | Use the digital meter to dispense 10L, 20L, and 25L of SAE100 gear oil | Measured volumes: 10.02L, 20.01L, 25.03L--all within ±0.5% accuracy range |
| Mobility & Stability | Move the trolley (with a 60Kg drum) across uneven workshop floors (50m distance) | Trolley maneuvers smoothly via castors; fixed wheels maintain stability; drum remains secured by clamping device |
| Pressure Resistance | Operate the pump at max flow pressure (24 Bar) for 2 hours with hydraulic oil | Hose (SAE 10R2AT) shows no swelling or leakage; pump maintains consistent 18 L/Min flow |
| Temperature Adaptability | Test the digital meter and hose at -20℃ (cold storage) and +60℃ (heated workshop) | Meter retains accuracy; hose remains flexible (no brittleness at low temp or softening at high temp) |
The YD51-012A Trolley-Mounted 3:1 Oil Dispenser Kit solves the key challenges of mobile oil dispensing: "limited mobility, imprecise measurement, and cumbersome setup". With integrated 4-in-1 design + high accuracy + rugged mobility as core strengths, it redefines efficiency for workshop and industrial oil transfer:
- All-in-One Solution: Combines air-operated pump, modular trolley, 4m hose, and digital meter in one kit--no need to purchase or assemble separate components. This saves 30% of setup time and eliminates compatibility issues between parts.
- Space-Efficient Trolley: The zinc-plated trolley holds both the drum and pump, reducing storage space by 50% compared to standalone pumps and drums. Its compact design fits through standard workshop doorways (width ≥80cm).
- ± 0.5% Accuracy Digital Meter: Enables precise oil measurement for tasks like customer billing (e.g., auto repair shops) or inventory tracking (e.g., industrial facilities). Unlike manual gauges that have ±2% error, this meter ensures no over-dispensing or under-dispensing.
- 3:1 Compression Ratio Pump: Delivers 18 L/Min flow and 24 Bar max pressure, handling medium-viscosity oils (up to SAE130) with ease. The 42mm suction tube reaches drum bottoms, minimizing residual oil (≤1L per 60Kg drum) and reducing waste.
- Heavy-Duty Trolley: The 20-60Kg capacity, zinc-plated finish, and 4-wheel design (2 fixed + 2 castors) make it easy to move across workshops--even with a full 60Kg drum. The drum clamping device prevents spills during transport, a critical safety feature.
- Wear-Resistant Hose: The SAE 10R2AT hose resists oil degradation and physical wear, with a 138 Bar working pressure that outperforms standard rubber hoses (typical 80 Bar). It remains flexible in extreme temperatures (-20℃ ~ +60℃), ensuring year-round use.
Scenario Requirement: A car repair shop services 30 cars daily (each needing 4-5L motor oil) and uses 60Kg drums. The shop needs a mobile, accurate dispenser to reduce labor time.
Operation Process:
- Setup: Secure a 60Kg oil drum to the trolley via the clamping device; connect the pump's F1/4"G air inlet to the shop's air compressor; attach the 4m hose and digital meter
- Dispensing: Use the meter to set the required volume (e.g., 4L for a sedan); the pump delivers oil at 18 L/Min--4L dispensed in ~13 seconds
- Mobility: Move the trolley between repair bays (50m distance) to service multiple cars without repositioning the drum
- Accuracy: Meter records each dispense, simplifying end-of-day inventory checks
Effect: Mobile design saves labor; precise meter reduces oil waste; 18 L/Min flow meets high daily demand.
Scenario Requirement: A manufacturing plant maintains 15 hydraulic machines (each needing 20L hydraulic oil monthly) and stores oil in 60Kg drums. The plant needs a stable, pressure-resistant dispenser for high-viscosity oil.
Operation Process:
- Setup: Mount the pump on the trolley's support; connect to the plant's air supply (8 Bar); attach the hose to the machine's oil inlet
- Dispensing: Operate the pump at 24 Bar max pressure to transfer 20L hydraulic oil (SAE120) in ~67 seconds; the meter ensures no overfilling
- Durability: Trolley's zinc-plated finish resists factory dust; hose (SAE 10R2AT) handles 24 Bar pressure without leakage
- Efficiency: One technician can maintain all 15 machines in 2.5 hours--half the time of manual dispensing
Effect: High-pressure performance fits hydraulic oil needs; durable build withstands factory conditions.
Scenario Requirement: A farm service team maintains 10 tractors (each needing 15L gear oil) on-site. The team needs a portable dispenser that works in cold (-5℃) and warm (+35℃) outdoor temperatures.
Operation Process:
- Setup: Load the trolley (with a 60Kg drum) into a service truck; at the farm, position the trolley near the tractors
- Dispensing: Use the digital meter to dispense 15L gear oil (SAE130) per tractor in ~50 seconds; the 4m hose reaches tractor oil tanks without moving the trolley
- Temperature Adaptability: Meter retains accuracy at -5℃; hose remains flexible for easy handling
- Portability: Trolley's compact size fits in the truck; castors work on gravel farm paths
Effect: On-site mobility meets farm needs; temperature resistance adapts to outdoor conditions.
A1: Error messages usually stem from pressure or connection issues. Solutions:
- Check Working Pressure: Ensure the pump provides at least 5 Bar (minimum for the meter)--low pressure triggers "LOW PRESS" errors
- Inspect Inlet Thread: Tighten the 1/2 Bsp/NPSM oil inlet thread (loose connections cause air gaps and "FLOW ERROR" messages)
- Reset the Meter: Turn the meter off and on to clear temporary glitches. If errors persist, contact the manufacturer to calibrate the meter
A2: No. The trolley's maximum capacity is 60Kg--exceeding this limit will cause:
- Trolley Damage: Castors or fixed wheels may bend or break under excess weight
- Safety Risks: The drum clamping device cannot secure heavy drums, leading to potential spills or drum tipping
- Reduced Mobility: The trolley will be difficult to maneuver, even on flat surfaces. For 80Kg drums, use a heavy-duty trolley (rated for ≥100Kg) and check compatibility with the YD51-012A pump separately
A3: To maintain hose flexibility at low temperatures:
- Pre-Warm the Hose: Before use, wrap the hose in a heated blanket (set to 10-15℃) for 10 minutes--this softens the SAE 10R2AT material
- Avoid Kinking: Store the hose coiled (not folded) when not in use--kinks weaken the material and increase brittleness
- Use Low-Temp Oil Additive: Mix a small amount of oil viscosity reducer (compatible with your oil type) to lower the oil's freezing point, reducing strain on the hose
A4: Cross-contamination is prevented with thorough cleaning:
- Flush the Pump: Run 5-10L of the new oil type through the pump to flush residual old oil
- Clean the Hose: Disconnect the hose and flush it with the new oil (or a compatible solvent, e.g., mineral spirits for petroleum-based oils)
- Calibrate the Meter: After cleaning, test the meter with 10L of the new oil to ensure accuracy
- Wipe External Parts: Clean the trolley and pump exterior with a dry cloth to remove oil residue. Never switch between incompatible oils (e.g., mineral oil to synthetic oil) without full cleaning
