What Are Engine-Driven Transfer Pumps?

Engine-driven transfer pumps are self-contained pumping units powered by their own petrol or diesel engine — completely independent of any external electrical supply. Unlike electric diesel transfer pumps that require a 12V battery, 240V mains or 3-phase connection, engine-driven pumps start up and run anywhere — making them the only practical choice for remote sites, large rural properties and locations where no power infrastructure exists.

A-FLO's engine-driven pump range from Ultraflo covers petrol and diesel engine configurations in both 1-inch and 2-inch pump sizes, with Viton seals throughout for compatibility with diesel fuel, biodiesel blends and water. The Honda GX25-powered 1-inch diesel transfer pump rounds out the range with Honda's renowned engine reliability for light-duty portable applications.

Petrol Powered Diesel Transfer Pumps

A-FLO's petrol engine-driven diesel transfer pumps from Ultraflo combine a reliable petrol engine with a Viton-sealed pump body rated for diesel fuel and water transfer. Available in cast iron construction for maximum durability in demanding applications, petrol-powered models are the most portable option in the engine-driven range — suited to farms, construction sites and any application where a lightweight, highly mobile pumping unit is needed.

The 6.5HP petrol engine model with 2-inch cast iron pump body delivers the highest flow rate in the petrol range — suited to bulk transfer applications. The 2.4HP models in 1-inch and 1.5-inch configurations provide a compact, lightweight solution for lower-volume portable refuelling.

Diesel Powered Engine-Driven Transfer Pumps

Diesel engine-driven transfer pumps run on the same fuel they're transferring — a significant logistical advantage on diesel-heavy mine sites, construction projects and transport depots where petrol may not be readily available. A-FLO stocks Ultraflo 4HP diesel engine driven pumps in both cast iron and aluminium pump body configurations, both featuring Viton seals for diesel and water compatibility.

Both diesel models feature a 2-inch pump outlet with roll frame for easy repositioning around site. The cast iron pump body suits high-abrasion environments and long-term continuous duty applications. The aluminium body offers a lighter-weight alternative where portability is a priority without sacrificing the Viton seal protection required for fuel handling.

Honda GX25 Diesel Transfer Pump

The 1-inch Honda GX25 diesel transfer pump combines Honda's renowned engine reliability with a compact, lightweight pump body suited to portable diesel transfer applications. The Honda GX25 is a four-stroke engine known for its fuel efficiency, easy starting and long service life — making it the preferred choice for operators who need a reliable portable pump they can depend on day after day in the field.

This model is well suited to agricultural operations, light construction and any application requiring a compact, dependable diesel transfer pump that starts first time and runs reliably in remote conditions without the need for any external power.
