Model: PVC90R SA7V90R0
Applicable Excavator Models: Caterpillar (CAT) E307D, LiuGong LG907, LiuGong LG908, Kobelco SK75. This gear pump is specifically engineered to meet the hydraulic needs of these diverse excavator models, ensuring seamless integration and reliable operation.
2. Performance Specifications
Displacement
The displacement of the gear pump is 90 cc per revolution. This displacement value is a key determinant of the volume of hydraulic fluid the pump can transfer in each rotational cycle. A relatively large displacement of 90 cc enables the pump to supply sufficient hydraulic power to drive various excavator functions efficiently, such as bucket digging, boom lifting, and swing operations.
Rated Pressure
It is rated to operate at a pressure of [X] bar. This rated pressure is the maximum pressure the pump can sustain continuously during normal working conditions. It ensures that the hydraulic system can generate the necessary force to perform the excavator's tasks effectively.
Maximum Pressure
The pump can withstand a maximum pressure of [X + ΔX] bar for short - term peak loads. This provides an extra safety margin during situations where the excavator may encounter sudden high - stress operations, like when breaking through tough soil or debris.
Flow Rate
At the rated speed of the excavator's engine, the pump can achieve a flow rate of [X] liters per minute. The flow rate is directly related to the speed of the hydraulic actuators in the excavator. A higher flow rate allows for quicker movement of components such as the boom, arm, and bucket, enhancing the overall productivity of the excavator.
