What is a high-volume diesel refuelling gun?

A high-volume diesel refuelling gun is a heavy-duty nozzle designed for fast bulk fuel dispensing at 80–120+ L/min. Unlike standard automatic nozzles suited to light vehicles, high-volume refuelling guns are engineered for large trucks, earthmoving plant, mining equipment and fuel depots where maximum throughput is critical.

What is a dry-break refuelling system?

A dry-break refuelling system uses a matched nozzle and receiver coupling that seals completely when disconnected — preventing fuel spillage or drips at the point of connection and disconnection. Flomax-compatible dry-break systems are commonly used in mining and heavy equipment operations where spill prevention and environmental compliance are required.

What is a ball-lock refuelling nozzle?

A ball-lock refuelling nozzle uses a ball-lock coupling mechanism to secure the nozzle to the receiver during refuelling, providing a positive, vibration-resistant connection. This is particularly important during high-flow dispensing or vehicle refuelling at elevated pressure, where an unsecured nozzle could dislodge. Colour coding (e.g., red #1 for engine fuel) helps prevent misfuelling.

Does A-FLO supply Flomax dry-break nozzles and receivers?

Yes. A-FLO supplies Flomax coolant nozzles and receivers, Flomax engine nozzles with ball-lock plugs, fuel nozzles with ball-lock and swivel connections, and compatible aluminium fuel receivers. This range supports complete dry-break refuelling point installations for heavy vehicle and mining equipment applications.

What accessories does A-FLO supply for high-volume refuelling points?

A-FLO supplies a range of high-volume refuelling accessories including Flomax nozzle and receiver sets, ball-lock connections, swivel joints for hose flexibility, reinforced high-pressure hoses, and vapor control components. These accessories are used to build complete, safe and spill-free bulk diesel dispensing points for service stations, fuel depots and fleet operations.

Overview

Why High-Volume Refuelling Guns for Fleet & Bulk Operations?

In high-throughput refuelling environments — fuel depots, mining sites, fleet yards and heavy vehicle service stations — refuelling speed, spill prevention and connection security are critical. Standard automatic nozzles at 45–80 L/min are too slow for large tanks and extended refuelling windows. A-FLO's high-volume refuelling gun range addresses these requirements with:

High-volume refuelling advantages

High flow / low pressure drop — engineered to maximise throughput at the dispensing point without restricting pump output
Precision metering and control — accurate, controlled dispensing even at high flow rates
Dry-break connections — Flomax couplings prevent spills at connection and disconnection for environmental compliance
Ball-lock security — positive locking mechanism prevents nozzle disengagement during dispensing
Vapor control — reduces fuel vapour emissions at the dispensing point
Reinforced hoses — heavy-duty hose construction rated for continuous high-pressure dispensing
