Heavy Duty Drum Pump 34L/Min 925mm Suction For Workshops / Farms / Sites
| Parameter Category | Specific Specification |
|---|---|
| Model | YD51-004C (Heavy-duty manual drum pump, engineered for high-volume liquid transfer from 200-gallon drums in industrial workshops, large farms, construction sites, and commercial storage facilities) |
| Product Type | 200-gallon drum-compatible heavy-duty manual pump, integrating "high-flow performance + rugged chrome-plated steel + deep suction" to handle large-scale liquid transfer tasks |
| Basic Parameters |
|
| Test Item | Test Condition | Test Result |
|---|---|---|
| High-Flow Stability | Operate at 40 strokes/min to transfer diesel from a 200-gal drum for 2 hours | Flow rate remains steady at 34 L/min (850 cc/stroke × 40 strokes/min); no pressure drop or flow fluctuation |
| Leak-Proof Performance | Fill the pump with hydraulic oil (viscosity 46 cSt), operate for 1 hour at max flow | Nitrile seal ring maintains a tight seal; no leakage at adaptor, piston, or pipe joints; 100% liquid retention |
| Durability | Perform 15,000 consecutive strokes (simulate 1 month of heavy use) with 34 L/min flow | Chrome-plated pipe no bending; PP piston no wear; reinforced adaptor thread no stripping; pump functions normally |
| Suction Efficiency | Test suction from a 200-gal drum with 5L residual oil at the bottom | 925mm suction head extracts 4.8L of residual oil (96% extraction rate); minimal waste |
The YD51-004C Heavy-Duty Manual Drum Pump addresses the limitations of lightweight pumps: "slow flow, shallow suction, and fragile build". With 34 L/min high flow + 925mm deep suction + rugged chrome steel as core strengths, it is built for large-scale 200-gallon drum transfer tasks.
- 34 L/min Rapid Transfer: The 850 cc per stroke flow rate and 40 strokes per minute speed enable transferring 34L of liquid per minute - enough to empty a 200-gallon drum (≈757L) in just 22 minutes.
- Wide Inlet/Outlet Design: The φ38.6mm inlet and φ19mm outlet work together to minimize flow resistance.
- Thickened Chrome-Plated Steel Pipe: Resists rust and scratches while withstanding accidental impacts.
- Reinforced Nitrile Seal: Thicker than standard seals (2mm vs. 1mm), ensuring it can handle high-flow pressure without leaking.
- Sturdy PP Piston: Designed to withstand the pressure of 850 cc per stroke while moving smoothly.
- 925mm Extra-Long Suction Head: Reaches the bottom of tall 200-gallon drums, extracting 96% of the liquid.
- 2" G-Thread Reinforced Adaptor: Features reinforced threads that lock securely into standard drum bungs.
Scenario Requirement: A manufacturing workshop transfers 500L of hydraulic oil daily from 200-gallon drums to 10 pieces of machinery (50L each).
- Installation: 2 workers attach YD51-004C to the drum (2 minutes)
- Transfer: Operate the pump at 40 strokes/min - 50L hydraulic oil transferred per machine in ~1.5 minutes
- Efficiency: 10 machines serviced in 15 minutes
Scenario Requirement: A farm with 20 tractors (each needing 100L diesel per day) uses 200-gallon drums of diesel.
- Setup: Install YD51-004C on the diesel drum
- Refueling: Transfer 100L diesel per tractor in ~3 minutes
- Convenience: The 925mm suction head empties the drum completely
Scenario Requirement: A construction site has 5 large generators (each needing 200L gasoline weekly) and uses 200-gallon drums of gasoline.
- Mobility: 2 workers carry the 2kg pump to the gasoline drum
- Fueling: Operate the pump to transfer 200L gasoline per generator in ~5.9 minutes
- Safety: The nitrile seal prevents gasoline leakage
A1: High viscosity increases flow resistance - solutions:
- Warm the Oil: Heat the hydraulic oil to 40-50℃ to reduce viscosity
- Adjust Stroke Speed: Increase strokes to 45 per minute
- Clean the Inlet: Check the φ38.6mm inlet for debris
A2: Yes, but verify the drum's bung size and height first.
A3: Heavy handles are due to friction or improper alignment - fixes:
- Lubricate the Piston: Apply a small amount of the liquid being transferred
- Check Pipe Alignment: Ensure the main pipe is straight
A4: Yes, but take extra safety precautions:
- Secure the Drum: Use drum chocks to keep the 200-gallon drum stable
- Use a Splash Guard: Attach a plastic splash guard to the φ19mm outlet
