Performance Test Results
| Test Item | Test Condition | Test Result |
| Flow Stability | Operate at 12V/24V to transfer diesel for 2 hours | Flow rate remains 50±1 L/min; motor surface temp ≤60℃ (no overheating) |
| Self-Priming Efficiency | Test suction from 3m head with diesel | Self-primes in 8 seconds; maintains stable flow until barrel is empty |
| Durability | 60 continuous 1-hour cycles with kerosene | Cast iron parts no wear; full-copper motor no burnout; filter traps 99% debris |
| Safety Protection | Simulate overpressure (8m head) and dirty oil intake | Bypass valve activates instantly; filter prevents clogging; viewer detects contamination |
Product Features
Full-Copper Motor & Dual Voltage: Power & Versatility
- 100% Full-Copper Motor: Outperforms aluminum-coil motors with lower heat generation and 50% longer service life (10+ years). It runs continuously for 2+ hours--critical for batch refueling tasks.
- 12V/24V Compatibility: Works with car/truck batteries (12V) and heavy machinery batteries (24V), eliminating the need for multiple pumps. Ideal for sites with mixed power sources.
Cast Iron Durability & Smart Safety
- Rugged Construction: Cast iron casing, steel rotor, and cast iron impeller withstand impacts, corrosion, and harsh conditions (dust, humidity). Unlike plastic pumps, it resists cracking in farms or construction sites.
- Built-In Protection: Bypass valve prevents overpressure damage; accessible filter reduces maintenance time; dirty oil viewer avoids machinery damage from contaminated oil. The handheld switch enables one-hand operation for convenience.
Fast Flow & Self-Priming: Efficiency & Ease
- 50 L/min Rapid Transfer: Cuts refueling time by 80% vs. manual pumps. For example, 10 tractors (80L each) are refueled in 19 minutes--vs. 4 hours manually.
- 3m Self-Priming Suction: Skips pre-filling and reaches barrel bottoms, leaving only 2-3L residual oil. Saves fuel costs and reduces waste.
Application Scenarios
Construction Site Machinery Refueling
Scenario: A site refuels 8 excavators (150L diesel each) daily with 24V machinery batteries.
Process: 1. Connect to 24V battery via 2m cable; 2. Transfer 150L in ~3 minutes/excavator; 3. Bypass valve protects high tanks.
Effect: 8 excavators refueled in 24 minutes; no project delays from slow manual transfer.
Agricultural Farm Tractor Refueling
Scenario: A farm refuels 12 tractors (80L diesel each) with 12V batteries in the field.
Process: 1. Carry 21kg pump to drums; 2. Plug into tractor battery; 3. Transfer 80L in ~1.6 minutes/tractor.
Effect: Portable for field use; cuts labor time by 75%; filter traps farm debris.
Marina Boat Fueling
Scenario: A marina refuels 10 boats (60L diesel each) with 12V batteries; tanks are 5m high.
Process: 1. Connect to boat battery; 2. Use 7m head to transfer 60L in ~1.2 minutes/boat; 3. Viewer checks for water contamination.
Effect: Saltwater-resistant cast iron; no fire risks (gasoline prohibited); fast service for customers.
Frequently Asked Questions
Q1: Why is flow lower at 12V than 24V?
A1: Normal--12V delivers ~45 L/min (vs. 50 L/min at 24V) due to lower motor torque. Optimize by: 1) Using fully charged batteries; 2) Keeping hoses straight; 3) Cleaning the filter monthly.
Q2: Can I modify it for gasoline?
A2: No--gasoline vapors are explosive (sparks from electrical parts risk fire), and it degrades seals. Modifications void the warranty and cause safety hazards. Use only diesel/kerosene.
Q3: Self-priming fails--what to do?
A3: Fix air leaks or clogs: 1) Tighten inlet/outlet hoses; 2) Clean the filter; 3) Pour 200ml diesel into the inlet to prime manually.
Q4: How to maintain the pump?
A4: 1) Flush with 5L clean diesel after use; 2) Clean the filter every 10 uses; 3) Store in dry areas; 4) Use original parts for replacements.
