Aeromotive 3.5 Brushless Gear Pump-External
The market leader in fuel delivery systems and components, Aeromotive introduces its first brushless fuel pump series. The 3.5 Brushless Gear pump provides the Pro-Series Fuel Pump performance the world has come to trust and depend on, now available with the latest Spur-Gear pumping mechanism and brushless-motor technology. Built for up to 90 psi of sustained pressure, this new pump supports Pro-Series flow at higher pressures with minimal drop in flow. This new brushless spur-gear pump is able to move more fuel and sustain higher pressures without failure.
Aeromotive 3.5 Brushless Gear Pump-External
Brushless motors employ sensors to monitor rotor angle to provide faster and more reliable phase shifting, producing more torque capacity and motor efficiency. Instead of the armature rotating, in a brushless motor the magnets rotate around the armature and the motor controller manages the phase shift to keep the motor rotating under load (load is related to pressure in a fuel pump). With more torque per watt and a higher torque to weight ratio, brushless motors produce lower noise and deliver higher reliability.
With a higher level of efficiency, down to fractions of a second in design speed control, the new Aeromotive brushless fuel pumps provide precise control of fuel pump RPM as pressure rises, better maintaining pump RPM and flow, producing a flatter flow curve. Tight tolerances result in less current draw, less heat and extended life. Now there is the ability to upgrade to a premium brushless pump for faster, more reliable and uninterrupted fuel delivery with less power consumption and potential for wear or failure.
