Part Number: 07429 – 71203
Application: Specifically designed for Komatsu bulldozers, including models D53A – 16, D53A – 1, D57 – 1, and D58 – 18.
Type: Hydraulic gear pump, which is a key component of the bulldozer's hydraulic system, responsible for providing hydraulic power to drive various hydraulic components.
Technical Specifications
Displacement: Usually within the range of 15 – 25 cm³/rev. This displacement is suitable for meeting the hydraulic system requirements of medium – sized bulldozers, ensuring a stable oil supply for the blade – lifting cylinder, steering cylinder, and other components.
Rated Pressure: Around 18 – 22 MPa (2610 – 3190 psi). This is the pressure at which the pump can continuously operate stably under normal working conditions to ensure the normal operation of the hydraulic system.
Peak Pressure: Can reach 28 MPa (4060 psi) to cope with short – term high – load situations, such as when the bulldozer is working in tough terrains or facing large – resistance objects.
Rated Speed: 1600 – 2000 rpm, which is adapted to the engine speed of the above – mentioned bulldozer models. The engine of these bulldozers runs at a certain speed, and the pump's rated speed needs to match it to ensure efficient power transmission.
