Leading-Edge Technology – Brushless BLDC Fuel Pumps

At Carter, we have been developing new generations of brushless BLDC fuel pumps since 2008. Brushless DC fuel pumps are the latest technology and have numerous advantages over brushed pumps:

  • 500% increased life expectancy
    • Wear components eliminated (brush and communicator)
  • 30% higher pressure and flow capabilities
    • 1-2 Bar pressures and 60-240 LPH flows
    • More efficient than conventional brush motors
  • Better fuel resistance
    • Electrical components are sealed internally for better fuel resistance, less corrosion and longer life expectancy
  • Perform better in harsh operating environments
    • Electronic commutation unaffected by high vibration
  • 12V and 24V applications
    • Equal durability, package size and performance across these applications

Integrated In-Tank Fuel Pumps, Modules and Hangers

  • Use either brushed or brushless pumps and are typically used in automotive.

Brushed Fuel Pumps

  • In production
  • Designed for specific customer needs
  • More affordable solution to BLDC
  • Shorter life expectancy

Solenoid Fuel Pumps

  • Solenoid pumps use a piston, with an electromagnetic coil to generate fuel pressure and flow.
  • Electromagnetic coil and piston design eliminates moving commutation components resulting in longer life over brushed pumps.
  • These pumps serve many uses from small gasoline and diesel engines to medium-duty industrial applications. They can serve both 12V and 24V applications.
  • They can be supplied with an endless variety of inlet and outlet fitting types.

Rotary Vane Fuel Pumps

  • A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity (the pump).
  • The benefit of having vanes is they are allowed to slide into and out of the rotor and seal on all edges, creating vane chambers that do the pumping work.
  • These pumps service the low to medium pressure applications requiring medium to high flows.
  • Our customers use this style pump for applications from high performance racing carbureted engines to industrial engines.
  • They are suited for both diesel and gasoline applications.
