Overview

Aeromotive 3.5 GPM Brushless Variable Speed Gear Pumps

Take your fuel system to the next level with Aeromotive 3.5 gpm brushless variable speed gear pumps –part of their first-ever brushless fuel pump series. Designed to deliver the legendary performance of Aeromotive Pro-Series pumps, these advanced modules combine innovative spur-gear pumping technology with a high-efficiency brushless motor for exceptional flow, pressure capability, and durability. Capable of sustaining up to 90 psi of continuous pressure with minimal flow loss, these pumps maintain consistent fuel delivery under demanding conditions while supporting high-horsepower EFI and carbureted applications.

Unlike conventional brushed motors, the brushless design utilizes rotor-position sensors and electronic phase control to optimize efficiency, increase torque output, and reduce power consumption. The result is quieter operation, lower current draw, reduced heat generation, and improved reliability. Precise variable-speed control helps maintain pump RPM as fuel pressure increases, producing a flatter flow curve and more consistent fuel delivery. Tight manufacturing tolerances further enhance efficiency while extending service life in gasoline, E85, and methanol-fueled applications. Whether you are building a street/strip machine or an all-out race vehicle, Aeromotive 3.5 gpm brushless variable speed gear pumps deliver the flow, pressure, and reliability serious racers demand.
