How quickly will it empty my fuel can or tank?

The pump moves liquids at a maximum of 2.8 gallons (10.6 liters) per minute, which means a standard 5-gallon container can be emptied in roughly two minutes under ideal conditions. Actual time varies with hose routing, liquid viscosity and battery charge level.

• Maximum flow: 2.8 GPM / 10.6 LPM
• Typical 5-gallon transfer time: about 2 minutes
• Works with fuels, diesel, water and many non-corrosive liquids

What power options does this pump support for off-grid use?

Demlox offers dual power modes: recharge via USB Type-C for modern batteries or run on four AA batteries when USB power isn’t available. This flexibility helps you keep working outdoors or at remote sites without an AC outlet.

• USB-C recharging for low-maintenance power
• 4 × AA battery compatibility as backup power
• LED indicators (where applicable) help monitor charge or operation

How do I control flow and avoid overfills or spills?

The pump includes a hand-operated nozzle that gives you precise start/stop control and variable flow, so you can fill small tanks and containers without splashing. The nozzle design reduces fuel waste and makes brief stops on the job safer.

• Hand nozzle for instant stop and adjustable flow
• Retractable intake pipe fits common container openings
• 51-inch discharge hose for flexible reach and positioning

What containers and situations is this best suited for?

Designed for versatility, the Demlox transfer pump adapts to many everyday fueling and liquid-moving tasks. The retractable intake pipe and full-length hose let you work with jerry cans, pails, generators and small equipment while maintaining tidy storage.

• Intake pipe length: approx. 30–43 cm to fit varied neck depths
• Discharge hose length: 130 cm (51 inches) for reach
• Ideal for fuel, diesel, water, and non-corrosive cleaning solutions

Who this is for: The Demlox portable transfer pump is built for homeowners, gardeners, mechanics, small-fleet operators and outdoor enthusiasts who need a fast, controllable way to move fuel and liquids without permanent pump installations.
