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. Features: ORB-12 inlet and ORB-10 outlet ports. For EFI applications use regulator P/N 13134 or P/N 13305. For carburetted applications use regulator P/N 13202 or P/N 13212. Capable of 90-PSI continuous operating pressure, 150 PSI peak pressure, base plus boost. Fully submersible for custom, in-tank placement. Perfect for 'blow-through' carburetted engines up to 2,000 FWHP. Fuel injected engines: up to 2400 FWHP - naturally aspirated up to 1800 FWHP - forced air induction Carburetted engines: Up to 2600 FWHP - naturally aspirated Up to 2000 FWHP - forced air induction E85 Compatible, reduce max FWHP by 30% Lighter than the traditional Pro-Series pump. Reduced current draw at higher, EFI pressures. Extended service life in methanol and ethanol. New integral spur-gear pumping mechanism. 90-PSI continuous operating pressure and up to 150-PSI peak pressure, base plus boost. Integral, external brushless controller for clean installation, cooler fuel and enhanced reliability. ORB-12 inlet and ORB-10 outlet ports. EFI Rated flow of 1,250 lbs./hr. @ 40 psi, 13.5 volts Carb Rated Flow of 1,350 lbs./hr. @ 9 psi, 13.5 volts 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.
