AIGMlSON 12V 260W Diesel Transfer Pump 45 L/min — Cast-Iron, Low-Noise with Bypass Valve

AIGMlSON's 12V 260W diesel transfer pump is a compact electric pump that moves up to 45 liters per minute and is built for durable, low-noise diesel, biodiesel, and kerosene transfer.

This 12V pump combines a cast-iron housing, alloy-steel impeller, and a copper-wound motor to deliver reliable fuel transfer for workshops, agricultural machinery, and service vehicles. Designed for portability and frequent use, it includes safety features such as a bypass valve and a stainless-steel intake filter to protect the motor and minimize contamination. It requires a 25 mm hose (sold separately) and is intended strictly for diesel-type fuels and kerosene — not for gasoline, water, or other low-flash-point liquids.

How fast and efficient is this pump for routine refueling?

The pump transfers fuel at up to 45 L/min, driven by a 260W motor that balances power and energy draw from a 12V supply. Its construction focuses on consistent flow with reduced vibration and noise, making it suitable for repeated fills without excessive wear.

• Maximum flow rate: 45 liters per minute
• Motor power: 260 watts on 12V DC
• Low-noise operation thanks to sturdy housing and quality motor windings
• Alloy-steel impeller for long service life

What safety features prevent overheating and contamination?

Built-in protections include a bypass valve to relieve pressure and prevent motor overload or overheating during restricted flow. The stainless-steel intake screen keeps particulates away from the impeller and motor, reducing the risk of clogs and premature failure.

• Internal bypass valve to avoid excessive back pressure
• Stainless-steel filter net to trap debris
• Cast-iron housing resists corrosion and mechanical stress
• Extra-thick copper wires for improved heat dissipation

What fuels and hoses are compatible with this unit?

This pump is intended for diesel, biodiesel blends, and kerosene only. It must not be used with gasoline, water, engine oil, alcohol, LPG, or other low-flash-point liquids. The pump is sized for 25 mm (1-inch) hose fittings; hoses and clamps are not included and must be purchased separately.

• Compatible fluids: diesel, biodiesel, kerosene
• Not compatible: gasoline, water, engine oil, alcohol, LPG
• Hose requirement: 25 mm (approx. 1") inner diameter
• Includes motor and filtered inlet; hose and fittings sold separately

How do I use and install the pump safely in a vehicle or tank setup?

Mount the pump securely near the fuel source, connect to a 12V DC supply with appropriate-rated wiring and fusing, and use a 25 mm fuel hose with proper clamps. Ensure the intake filter faces the fuel source and test with a short run to verify seal integrity and that the bypass valve behaves normally.

• Secure mounting to reduce vibration and noise
• Use correct 12V wiring and inline fuse for safety
• Install 25 mm fuel hose and tighten clamps properly
• Perform a brief test run and inspect for leaks or overheating

Who is this for: technicians, fleet operators, farmers, and DIY mechanics who need a robust, portable diesel transfer solution that balances flow rate and durability. It's a practical choice for refueling engines, topping off tanks, or transferring diesel between containers where a 12V power source is available and the operator understands fuel-handling safety. Not recommended for use with petrol, water, or other incompatible liquids.
