Product Introduction
The gear pump, also known as the supply pump, is the starting point of fuel flow in Denso's HP3 to HP7 common rail systems. It is responsible for drawing fuel from the tank and delivering a steady, pressurized flow to the high-pressure chamber. Without a properly functioning gear pump, the entire injection system would suffer from low rail pressure, misfires, or injection delay.
At Abosede Diesel, we manufacture gear pumps with premium-grade materials and fine tolerances to ensure efficient fuel delivery, smooth engine start-up, and consistent rail pressure under all load conditions.
