Verschiebung: Normalerweise im Bereich von 30 – 50 cm³/rev. A larger displacement can provide sufficient flow to meet the high – power requirements of the D85 bulldozer's hydraulic system.
Nenndruck: 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.
Spitzendruck: Kann erreichen 30 MPA (4350 Psi) kurz zu bewältigen – Begriff hoch – load working conditions, such as when the bulldozer encounters large – resistance objects during operation.
Bewertungsgeschwindigkeit: 1800 – 2200 Drehzahl, which is adapted to the engine speed of the D85 bulldozer. Zum Beispiel, 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.
Höchstgeschwindigkeit: Allgemein, it does not exceed 2500 Drehzahl. Prolonged operation at high speeds should be avoided to prevent overheating and excessive wear of the pump.
Rotationsrichtung: Usually counter – im Uhrzeigersinn (Gegen den Uhrzeigersinn) 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.
Häfen: The inlet port is usually SAE 12 (1 – 1/8" NVV), and the outlet port is SAE 10 (3/4" NVV). The larger – diameter inlet port is conducive to improving the oil – suction capacity and ensuring a sufficient oil supply to the pump.
Gewicht: Etwa 25 – 35 kg. The specific weight may vary slightly depending on the specific design and material of the pump.
