Diesel & Fuel Transfer Pumps

Flow Rate and Motor Power Selection

Transfer volume dictates the required pump capacity and motor size. Light-duty top-ups and barrel emptying typically need compact pumps delivering 5 L/min to 12 L/min (roughly 3.2 GPM), drawing minimal current with motors around 25W to 130W. These units handle targeted fluid shifts without splashing or overflowing small sumps.

Bulk dispensing into heavy vehicles, site generators, or machinery day-tanks requires higher delivery speeds. Units delivering 30 L/min, 45 L/min, or up to 60 L/min cut refueling times on busy sites. Motors for high-capacity applications range from 150W up to 990W, maintaining flow velocity even through long delivery hoses.

• Low volume (5 to 12 L/min): Suitable for small reservoir draining, marine bilges, and precise oil top-offs.
• Medium volume (30 to 45 L/min): Standard output for agricultural machinery, tractors, and commercial vans.
• High volume (50 to 60 L/min): Recommended for rapid turnaround on heavy plant, bulk tanks, and earthmovers.

Voltage Configuration and Power Source

Power access at the transfer point determines your pump drive mechanism. For mobile service vehicles and roadside machinery refueling, a DC electric diesel transfer pump connects directly to vehicle electrics. Dual-voltage 12V / 24V DC models provide flexibility across mixed fleets of light commercial trucks and 24V heavy excavators.

Stationary maintenance bays benefit from hybrid DC/AC units or dedicated 220V AC motors for continuous operation without draining vehicle batteries. Cordless operations can utilize rechargeable battery options, including models compatible with standard 18V tool battery platforms, eliminating trailing cables around machinery tracks.

• 12V DC: Connects to standard service vehicle batteries using heavy-duty battery clamps.
• 24V DC: Delivers stable current for heavy transport, construction equipment, and marine vessels.
• 220V AC: Ideal for fixed workshop installations and permanent transfer stations.
• Cordless / 18V Battery: Enables swift fuel drops in remote locations without vehicle hookups.

Housing Materials and Media Compatibility

Pump longevity depends on matching the housing metal and internal seals to your target media. Submersible transfer pumps feature stainless steel or aluminum alloy shells to withstand corrosion, abrasive grime, and continuous fluid immersion. Stainless steel bodies offer high resistance when cycling between diesel, kerosene, and water.

Media compatibility varies significantly across models. Most pumps in our catalog handle diesel, kerosene, light oils, and clean or sewage water. Standard diesel units must never be used with petrol or solvents unless the product listing explicitly verifies gasoline compatibility. Check specific product specifications for chemical and viscosity tolerances.

• Stainless Steel Housing: High corrosion resistance for submersible use in damp tanks and marine environments.
• Aluminum Alloy Shell: Lightweight build suitable for portable, hand-carried emergency kits.
• Fluid Compatibility: Verify your specific media (diesel, kerosene, oil, or water) against product data sheets before commissioning.
