Product Guide

Diesel Transfer Pumps — 12V, 24V, 240V & Air-Operated for Australian Industry

A diesel transfer pump is a mechanical or electric device that moves diesel fuel from a storage tank to a vehicle, generator or piece of machinery — the core component of any on-site refuelling setup. A-FLO Equipment supplies professional diesel transfer pumps in 12V DC, 24V DC, 240V AC and air-operated (pneumatic) configurations for agriculture, mining, construction, transport and industrial applications across Australia — including complete kits with flow meters, hoses, nozzles and filtration.

Pump Types

Types of Diesel Transfer Pump — Which Is Right for Your Application?

Diesel transfer pumps are available in four power configurations — each suited to a different operating environment and power source. Matching the pump to your available power supply and daily fuel throughput is the most important selection decision.

Mobile & Field Use

12V DC Diesel Transfer Pump

Powered from a vehicle battery — the most common choice for ute-mounted, trailer and field refuelling setups. No external power source required. Typical flow rates 40–80 LPM. Ideal for agriculture, remote site access and mobile service vehicles where mains power is not available.

Heavy Vehicle & Truck

24V DC Diesel Transfer Pump

Powered from heavy vehicle batteries — suited to truck-mounted fuel setups, road train service vehicles and plant that runs 24V electrical systems. Higher flow rates than 12V with the same mobile flexibility for remote applications.

Fixed Depot Installation

240V AC Electric Diesel Transfer Pump

Mains-powered for fixed depot refuelling bays, workshed installations and high-volume dispensing. Higher and more consistent flow rates than DC pumps — typically 80–200+ LPM depending on model. The preferred choice for busy fleet depots and fixed on-site fuel stations.

Hazardous Area & Air-Powered

Air-Operated (Pneumatic) Diesel Pump

Powered by compressed air — no electrical ignition source, making them the required choice for hazardous area installations and environments where spark risk must be eliminated. Also suited to sites with compressed air infrastructure but limited electrical supply.

Diesel Transfer Pump Selector

Pump Type Power Source Typical Flow Rate Best Application
12V DC Vehicle battery 40–80 LPM Ute-mounted, trailer, farm & field refuelling
24V DC Heavy vehicle battery 60–100 LPM Truck-mounted, road train service, plant vehicle
240V AC Mains power 80–200+ LPM Fixed depot, workshop, high-volume fleet bay
Air-Operated Compressed air 40–120 LPM Hazardous areas, mining, no-spark environments
Engine-Driven Diesel engine 100–400+ LPM High-volume remote sites, no electrical supply
Installation Guide

How to Install a Diesel Transfer Pump

Installing a diesel transfer pump correctly ensures safe, efficient and compliant operation from day one. Follow these steps as a general guide — always refer to the specific manufacturer's installation instructions for your pump model and comply with local fuel handling regulations.

01

Choose the Right Location

Mount the pump on a stable, level surface as close to the diesel tank as practical — minimising suction lift improves priming and flow rate. Ensure adequate ventilation, accessibility for refuelling and clear space for maintenance. Avoid high-traffic areas and locations with excessive heat or direct ignition sources.

02

Secure the Pump

Fix the pump to the tank mounting bracket, trolley baseplate or surface mount using the provided hardware — ensuring it cannot shift or vibrate loose during operation. For mobile setups, verify all fasteners are rated for the transport vibration environment.

03

Connect the Suction Hose

Attach the suction hose from the pump inlet to the bottom outlet or dip tube of the diesel tank — use a foot valve to maintain prime. Ensure all connections are tight and the hose is diesel-rated. Any air leak on the suction side will prevent the pump from priming or maintaining flow.

04

Fit the Filter and Flow Meter

Install the fuel filter and water separator on the delivery side of the pump — before the flow meter. Fit the digital flow meter in line with the delivery hose. The meter should be oriented correctly for accurate reading as indicated by the directional arrow on the meter body.

05

Attach the Delivery Hose and Nozzle

Connect the diesel-rated delivery hose to the pump outlet — through the flow meter — and secure the automatic shut-off nozzle to the dispensing end. Confirm all hose clamp and camlock connections are tight before proceeding to power connection.

06

Power Connection

For 12V or 24V DC pumps — connect with appropriately rated cable and an inline fuse sized to the pump's current draw. Use a dedicated switch or relay rather than direct battery connection. For 240V AC pumps — connect via a weatherproof isolating switch with appropriate cable and circuit protection. Have a licensed electrician complete 240V connections where required by state regulation.

07

Prime and Test

Switch the pump on and allow it to self-prime — most modern diesel pumps prime within 30–60 seconds. Check all connections for leaks while the pump is running. Confirm fuel is flowing consistently through the nozzle and the flow meter is incrementing correctly before placing the system in service.

Installation safety note

  • Always follow the pump manufacturer's installation instructions — particularly for power connection, fusing and earthing requirements. Comply with local fuel handling regulations and AS1940. Where 240V connections are required, engage a licensed electrician. Never operate a diesel pump in a poorly ventilated enclosed space.
Fluid Compatibility

Can a Diesel Transfer Pump Be Used for Other Fluids?

Diesel transfer pumps are designed and rated for diesel — but buyers frequently ask whether they can be used for petrol, kerosene, biodiesel or other fuels. The answer depends on the pump's seal materials, motor rating and fluid compatibility specification. Never assume compatibility — always check the pump's rated fluid list before use with any alternative liquid.

? Compatible

Diesel

The primary rated fluid for all diesel transfer pumps — seals, motor and materials specified for diesel service.

? Compatible

Biodiesel (B20 or below)

Most diesel pumps are compatible with biodiesel blends up to B20 — confirm with manufacturer for higher blends as seal compatibility varies.

? Compatible

Kerosene

Compatible with most diesel-rated pumps — kerosene is a low-flashpoint combustible liquid with similar properties to diesel. Confirm with manufacturer.

? Compatible

Light Heating Oil

Generally compatible with diesel-rated pumps — similar viscosity and flashpoint to diesel fuel. Confirm specific pump compatibility before use.

? Check First

Mineral Oils & Lubricants

Viscosity varies significantly — confirm the pump's rated viscosity range before use with oils. High-viscosity oils may require a dedicated oil transfer pump rather than a fuel pump.

? Not Compatible

Petrol (Gasoline)

Never use a diesel-rated pump for petrol. Petrol degrades diesel pump seals and creates a serious fire and explosion risk. A pump rated for Class 3 flammable liquids is required under the ADG Code.

? Not Compatible

AdBlue (DEF)

AdBlue requires stainless steel and specific polymer wetted components — standard diesel pump materials corrode on contact. A dedicated AdBlue pump is always required.

? Not Compatible

Water & Aqueous Fluids

Diesel transfer pumps are not designed for water — internal components are not corrosion-protected for aqueous fluids and will fail rapidly if used with water-based liquids.

Frequently Asked Questions

Diesel Transfer Pump FAQ

What flow rate do I need for a diesel transfer pump?

Flow rate depends on the number of vehicles being refuelled, their fuel tank capacity and how quickly you need to turn around refuelling. As a general guide: 40–60 LPM suits light vehicles, farm machinery and smaller mobile applications; 80–120 LPM suits medium fleet depots and construction site bowsers; 150–200+ LPM suits high-volume heavy fleet depots and large on-site refuelling bays. A-FLO can advise on the right flow rate for your daily throughput — call 1300 235 623.

Why won't my diesel transfer pump prime?

The most common causes of a diesel transfer pump failing to prime are: an air leak on the suction side — check all suction hose connections and clamps; suction lift too high — the pump is mounted too far above the fuel level in the tank; blocked or missing foot valve — the foot valve at the base of the suction line maintains prime and must be clean and seating correctly; blocked inlet strainer — the suction strainer may be clogged with debris; or a worn pump rotor or vanes on a pump that has been in service for some time. If the pump runs but draws no fuel, start with the suction side and work forward.

Do I need a filter on my diesel transfer pump?

Yes — particularly for refuelling modern common rail diesel engines, which operate at very high injection pressures and are highly sensitive to fuel contamination. A 30-micron or finer fuel filter and water separator fitted on the delivery side of the pump removes particulates and free water before diesel reaches vehicle fuel systems — protecting injectors from contamination damage that can cost thousands to repair. A-FLO recommends filtration as standard on all diesel transfer pump setups.

Can I use a diesel transfer pump with a fuel management system?

Yes. A-FLO's FLUIDTRACK, PIUSI Bsmart and PIUSI 3000 Supreme fuel management systems can be integrated with a diesel transfer pump setup — adding access control via RFID card or PIN, driver and vehicle identification and digital transaction reporting. This allows every litre dispensed to be tracked by vehicle or driver for cost allocation, compliance records and theft prevention. A-FLO can design the complete pump and management system package for your operation.

What accessories do I need with a diesel transfer pump?

A complete diesel transfer pump setup requires: a digital flow meter for accurate litre counting; a diesel-rated delivery hose in the appropriate length and diameter; an automatic shut-off nozzle to prevent overfilling; a fuel filter and water separator to protect common rail engines; and a suction hose or foot valve for tank connection. For depot and fleet applications, a hose reel and fuel management controller complete the professional setup. A-FLO supplies complete pump kits with all accessories included.
