What to Look for When Choosing a Fuel Pump?

In today's fast-paced world, the range of fuel pump options can be daunting. Three questions cut through the noise and lead you to the right solution.

  • How fast do you want to refuel your vehicles?
  • How accurately do you want to measure the fuel you use?
  • Where is your fuel storage tank?
Choosing a fuel pump

How fast do you need to refuel?

Everyone wants to refuel quickly — but too fast creates problems. Excessive flow causes splashback, frothing, and spillage. If you're using an automatic shut-off nozzle, froth can repeatedly trip the sensor, forcing drivers to wait for it to settle and top up repeatedly — actually slowing the whole process down.

Match your flow rate to your vehicle type:

Fuel pump flow rates
Low Speed
40LPM
Cars, light vans, forklifts, jerry cans and small plant equipment.
Medium Speed
60LPM
Large vans, small rigid trucks, agricultural vehicles and large industrial plant equipment.
High Speed
80LPM
Buses, coaches, articulated vehicles, heavy plant, and quarry/mining equipment.

How accurately do you need to measure?

Higher accuracy metering costs more — but for any significant fuel operation, the extra cost is recovered quickly through tighter records and reduced uncertainty. There are two main meter types:

Fuel meter accuracy comparison
Standard
Nutating Disc Meter
±2%
  • Accuracy varies with delivery speed and fuel type
  • Should be calibrated after installation and regularly checked
  • Accuracy reduces further when topping tanks to the brim
  • Suited to smaller fleets with lower fuel volumes

To put the difference in practical terms — if a driver fills to 100 litres shown on the pump display:

Accuracy comparison at 100 L dispensed
±2% meter (nutating disc) 98–102 L actual — 4 L uncertainty
±0.5% meter (oval gear) 99.5–100.5 L actual — 1 L uncertainty
At 10,000 L/month with ±2% meter Up to 400 L unaccounted monthly
Remember: All key and card-operated fuel monitoring systems connect to the output of the meter in the pump. Your monitoring data can only ever be as accurate as the meter it's connected to. A worn, old or inaccurate meter will produce unreliable records — regardless of the system attached to it.

Where is your storage tank?

Tank location directly affects which pump will work for your installation. Underground tanks require a pump with sufficient suction lift to draw fuel from depth. Above-ground tanks need less suction but require installation that protects against leakage if dispensing equipment is damaged.

Always check that your pump's suction lift rating matches your actual installation — a pump rated to 2 m suction won't perform correctly in a system requiring 4 m. Match the specification to the system, not the other way around.
