Komatsu Dump Truck Injector Pump

Komatsu dump truck injector pump

The Komatsu dump truck injector pump is a high-pressure inline piston pump, capable of delivering fuel up to 1800 bar. Its body is made of aluminum alloy and wear-resistant steel, with thermal resistance up to 120 degrees Celsius. The precise hydromechanical operation ensures milligram-level fuel dosing and exact injection timing. The fuel inlet measures 12 millimeters, while the outlet is 8 millimeters, maintaining pressure fluctuation below 5 percent under standard operational conditions.

Internally, it features a central shaft supporting radial loads up to 2500 Newtons and corrosion-resistant single pistons. Pressure control is managed by a safety valve and precision spring, with total pump weight around 28 kilograms. Overall mechanical tolerance is below 0.02 millimeters, and the modular design allows part replacement without disassembling the entire pump. An internal lubrication system operating at 2.5 liters per minute ensures reliable performance.
