Verschiebung: Usually in the range of 30 – 50 cm³/rev. A larger displacement can provide sufficient flow to meet the high – power requirements of the D85 bulldozer's hydraulic system.
Rated Pressure: 20 – 25 MPa (2900 – 3625 psi). This is the continuous operating pressure that ensures the pump can stably supply hydraulic power under normal working conditions.
Peak Pressure: Can reach 30 MPa (4350 psi) to cope with short – term high – load working conditions, such as when the bulldozer encounters large – resistance objects during operation.
Rated Speed: 1800 – 2200 Drehzahl, which is adapted to the engine speed of the D85 bulldozer. For example, if the D85 is equipped with a Komatsu SAA6D140 engine, its rated speed is around 2000 Drehzahl, and the pump's rated speed needs to match the engine's output speed to ensure efficient power transmission.
Maximum Speed: Generally, it does not exceed 2500 Drehzahl. Prolonged operation at high speeds should be avoided to prevent overheating and excessive wear of the pump.
Rotation Direction: Usually counter – clockwise (CCW) when viewed from the drive end, but it is recommended to verify with the specific model of the D85 bulldozer or refer to the equipment manual.
Ports: The inlet port is usually SAE 12 (1 – 1/8" NPT), and the outlet port is SAE 10 (3/4" NPT). The larger – diameter inlet port is conducive to improving the oil – suction capacity and ensuring a sufficient oil supply to the pump.
Gewicht: Approximately 25 – 35 kg. The specific weight may vary slightly depending on the specific design and material of the pump.
