Fuel Additive Injection

Application Summary


Fuel Additive Injection


Improving or changing fuel performance by injecting fuel additives

How It’s Used

Pumping a wide variety of fuel additives, at a constant, controlled flow rate, into an injection manifold to facilitate mixing during fuel dispense

Key Feature

Chemical resistant pump materials

End Equipment

Fuel dispensing equipment

Pump Function



Corrosion inhibitors, lubricants, anti-icing additives, dyes, detergents, static dissipating additives

Flow Rate

0.5 to 10 L/min (7.9 to 159 USG/hr)

Differential Pressure

<40 psi (<2.76 bar)

Applications Overview

Fuel can be improved, changed or enhanced through the addition of fuel additives according to specific performance and usage requirements.

Additives can be added at the rack in a distribution terminal, at a service station style dispenser, or into the fuel stream dispensed from a delivery truck.

Typical examples include:

  • Refining additives
  • Detergent additives to keep fuel injectors clean
  • Color dyes to identify fuel grades
  • Lead-based additives for aviation
  • Corrosion inhibitors
  • Lubricants for extended engine and pump life
  • Anti-icing additives for jet fuel
  • Static dissipater additives

Micropump pumps deliver smooth, controlled flows of fuel additive into a fuel dispensing system.

Micropump Products Optimized for this Application

Micropump “suction shoe” style pumps are commonly used for this application. Series GB are best suited for lower flows, and Series GC for higher flows. Suction Shoe style gear pumps provide more consistent flow with varying differential pressure, and extended pump wear, than standard cavity style gear pumps. Suction shoe pumps also perform better with wide ranging temperature changes than cavity style pumps. Our integrated electromagnet EagleDrive™ provides variable, precise flow control in an energy efficient and compact package.
