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.
