Product Details
The YD51-012B Trolley-Mounted 5:1 Oil Dispenser Kit solves the critical pain points of high-viscosity oil handling: "clogged pumps, inaccurate measurement, and limited mobility". With 5:1 high-compression pump + precise digital meter + rugged mobile trolley as core strengths, it delivers unmatched efficiency for heavy-duty oil dispensing:
5:1 Compression Ratio Pump: Master of High-Viscosity Oil
- Powerful Oil Transfer: The 5:1 compression ratio generates 40 Bar max flow pressure, enabling smooth transfer of SAE240 high-viscosity oil-- a task that clogs standard 3:1 ratio pumps. This makes it ideal for industrial gearboxes and heavy machinery.
- Efficient Suction: The 42mm diameter suction tube reaches drum bottoms, minimizing residual oil (≤1L per 60Kg drum) and reducing waste. The 125 L/Min air consumption ensures consistent power for long-duration use.
Precise Digital Meter & Durable Hose
- ± 0.5% Accuracy Measurement: The digital meter eliminates guesswork in oil dispensing, critical for industrial inventory tracking and customer billing. Unlike manual gauges, it maintains accuracy even with thick, high-viscosity oils.
- SAE 10R2AT Hose: With a 138 Bar working pressure and oil-resistant material, the 4m hose withstands high-pressure output from the pump and resists degradation from heavy oils. Its length allows flexible dispensing without moving the trolley.
Rugged Modular Trolley: Mobility for Any Workspace
- 20-60Kg Capacity & Zinc Plating: The trolley handles full oil drums easily, while the zinc-plated finish resists rust and oil stains--perfect for humid workshops or outdoor farms.
- Smooth Maneuverability: 2 fixed wheels and 2 castors enable easy movement across rough surfaces (e.g., gravel, uneven concrete), making it suitable for both indoor industrial spaces and outdoor farmyards.
Application Scenarios
Industrial Gearbox Oil Refueling
Scenario Requirement: A manufacturing plant refuels 12 industrial gearboxes (each needing 25L SAE240 gear oil) monthly. The high-viscosity oil clogs standard pumps, and precise measurement is needed for inventory.
Operation Process:
- Setup: Secure a 60Kg SAE240 drum to the trolley; connect the pump's F1/4"G air inlet to the factory air supply; attach the 4m hose and digital meter
- Dispensing: The 5:1 pump transfers 25L oil per gearbox in ~107 seconds (14 L/Min capacity); the meter records each dispense for inventory
- Efficiency: 12 gearboxes refueled in ~21 minutes; no clogging or flow interruptions
- Durability: Trolley's zinc plating resists factory dust; hose handles 40 Bar pressure without leakage
Effect: High-compression pump solves clogging; precise meter simplifies inventory.
Heavy Machinery Service Center
Scenario Requirement: A service center maintains 8 excavators (each needing 30L hydraulic oil, SAE180) daily. The center needs a mobile dispenser to service machines in different bays.
Operation Process:
- Setup: Move the trolley to each excavator; secure the drum with the clamping device; connect the air supply
- Dispensing: Transfer 30L hydraulic oil in ~129 seconds; the 4m hose reaches the excavator's oil tank without repositioning the trolley
- Mobility: Trolley moves smoothly between service bays (concrete floors); castors lock for stability during dispensing
- Accuracy: Meter ensures no overfilling, preventing hydraulic system damage
Effect: Mobile design saves time; high-pressure pump handles SAE180 oil.
Large-Scale Farm Tractor Maintenance
Scenario Requirement: A farm services 15 tractors (each needing 20L gear oil, SAE200) seasonally. The farm has gravel paths, and oil must be dispensed outdoors.
Operation Process:
- Setup: Load the trolley (with 60Kg drum) onto a utility vehicle; transport to the farm's maintenance area
- Dispensing: Use the pump to transfer 20L oil per tractor in ~86 seconds; the digital meter verifies volume
- Outdoor Adaptability: Trolley navigates gravel paths; zinc plating resists rain and humidity; hose remains flexible in 10-30℃ outdoor temperatures
- Convenience: One technician handles all 15 tractors in ~21.5 minutes
Effect: Rugged trolley suits outdoor use; high-viscosity compatibility fits tractor needs.
Frequently Asked Questions
Q1: The pump clogs when transferring SAE240 oil. How to fix this?
A1: Clogging is usually due to insufficient air pressure or oil temperature. Solutions:
- Check Air Pressure: Ensure the air compressor provides 8 Bar (working pressure)--low pressure reduces pump power
- Warm the Oil: Heat the SAE240 oil to 30-40℃ (using a drum heater) to reduce viscosity
- Clean the Suction Tube: Remove the 42mm tube and flush it with diesel to clear residual oil. These steps restore smooth flow
Q2: Can the trolley hold drums smaller than 20Kg (e.g., 10Kg)?
A2: Yes, but use the drum clamping device properly:
- Adjust the Clamp: Tighten the clamping device to secure the 10Kg drum (loose clamps cause instability)
- Add Weight to Trolley: Place a small weight (e.g., 5Kg) on the trolley's empty side to balance the light drum--prevents tipping during movement
- Reduce Speed: Move the trolley slowly to avoid shifting the small drum. The trolley's design accommodates various drum sizes with minor adjustments
Q3: The digital meter's display is unreadable in bright sunlight. What to do?
A3: Improve visibility with these steps:
- Adjust Display Angle: Tilt the meter slightly downward to reduce glare
- Use a Sun Shade: Attach a small, portable sun shade (compatible with the meter's size) to block direct sunlight
- Calibrate Brightness: Check if the meter has a brightness adjustment button (refer to the user manual)--increase brightness for outdoor use. If no button exists, the shade is the most effective solution
Q4: How to maintain the pump to extend its service life?
A4: Key maintenance steps:
- Post-Use Flushing: After transferring high-viscosity oil, run 5-10L of low-viscosity oil (e.g., SAE30) through the pump to clear residual thick oil
- Clean the Suction Tube: Remove and rinse the tube monthly to prevent oil buildup
- Lubricate Connections: Apply a small amount of oil-resistant lubricant to the air inlet (F1/4"G) and oil outlet (M1/2"G) quarterly
- Store Properly: Keep the pump and trolley in a dry, ventilated area--avoid storing with oil in the pump, as it may clog over time
