Heavy-Duty Diesel Transfer Pump | 1/4 HP 10 GPM Electric Motor | Portable Toolbox

Refuel machinery anywhere using this self-priming 12v fuel transfer pump mounted inside a portable carry case. Driven by a 1/4 HP DC motor, this mobile diesel transfer pump moves up to 10 gallons per minute, letting you top off utility equipment straight from your truck bed tank. Features and Benefits - 1/4 HP 12V DC electric motor - Delivers a genuine 10 GPM flow rate to fill a 30-gallon tank in three minutes - Automatic shut-off nozzle assembly - Cuts fluid flow the second the tank fills to prevent costly overflows - Integrated steel carry case with handle - Keeps your hoses, cables, and nozzle neatly organized during transport - Internal thermal protection switch - Protects the electrical windings during its standard 30-minute continuous run rating Applications - Transferring diesel fuel from auxiliary pickup truck bed tanks to service machinery on the road - Filling forestry equipment, splitters, and stationary diesel power units deep off-grid - Dispensing light fuel oils and kerosene into heating tanks or commercial yard gear Key Compatibility Differences A common question is whether you can use a diesel transfer pump for gasoline. The short answer is no. This 12V DC unit is rated exclusively for diesel. Petrol has a much lower flashpoint than diesel, creating explosive vapours even below 45°F (7°C). Standard diesel transfer pumps are not explosion-proof; internal motor sparking can instantly ignite fuel vapour. Diesel also provides natural lubrication to internal vanes and seals. Running petrol through this mechanism strips that lubrication, leading to rapid seal degradation, overheating, and fire hazards. For site safety, keep this unit strictly on diesel duties and never substitute volatile, low-flashpoint fuels. What It Is A diesel transfer pump is a dedicated, self-contained fluid handling system designed to move heavy fuel oil from bulk storage tanks, IBCs, or barrels directly into plant and vehicle tanks. This model, the DCFD40, incorporates a 186 W (1/4 HP) electric motor running off standard 12V DC battery power. It delivers an operational flow rate of 37.85 L/min (10 GPM), cutting down turnaround times during site refuelling. Built into a self-contained portable toolbox, the unit includes an automatic shut-off nozzle as standard, which cuts fuel flow immediately once the receiving tank reaches capacity to eliminate waste and hazardous spills. Key Uses & Applications - Refuelling site excavators, dumpers, and telehandlers straight from drums or an IBC when ambient temperatures reach up to 43°C. - Mobile field servicing for agricultural tractors, combine harvesters, and forestry equipment running remote 12V DC battery connections. - Fleet yard topping-up for commercial vans and HGVs where dedicated forecourt fuel pumps are not accessible. - Transferring clean diesel fuel between bulk bowsers and static site storage vessels. - Fast top-ups for auxiliary site equipment, including diesel generators, lighting towers, and diesel-powered hydraulic power packs using the automatic shut-off nozzle to prevent overfilling.
