oem EX60 EX60-1 Hydraulic Pump Excavator Parts A10V43 Hydraulic Main Pump for Hitachi

Смещение: It can provide displacements of 18, 28, 45, 71, 100, and 140 ml/rev. For the A10V43 model, the displacement is usually 45 ml/rev.

Working Pressure: The nominal pressure is 28MPa, and the peak pressure can reach 35MPa. The intermittent working pressure (accounting for 10% of the cycle) is 31.5MPa. The absolute pressure of the oil inlet is 0.08MPa – 0.3MPa.

Скорость потока: The maximum flow rate is related to the driving speed and displacement. When the speed is at the maximum rated speed, the flow rate of the 45 ml/rev displacement pump can reach 117L/min.

Speed: The maximum speed is 2600rpm. The flow is proportional to the driving speed, and the speed can be appropriately increased when the displacement is reduced or the oil inlet pressure is increased.

Torque: The maximum torque at rated working pressure is 200Nm.
