Physical Characteristics:
Weight: It weighs about 44 kg2.
Dimensions: The single package size is 50x30x37 cm2. However, the actual installation dimensions on the excavator may vary, and it needs to be installed according to the specific structure of the EC55 and EC55B hydraulic systems.
Performance Parameters:
Displacement: There is no publicly available specific displacement data. But considering the working requirements of VOLVO EC55 and EC55B excavators, it is estimated that the displacement is designed to provide sufficient hydraulic power for the normal operation of the excavator's working devices, usually in the range of tens of milliliters per revolution.
Pressure: The main relief setting pressure of the VOLVO EC55B hydraulic system is 22 MPa1. This pump is designed to work stably within this pressure range to ensure the normal operation of the hydraulic system.
Rotation Speed: There is no specific public data on the rated rotation speed. However, for hydraulic pumps of this type in small - and medium - sized excavators, the rated rotation speed is generally around 1500 - 2000 rpm. Within this speed range, the pump can achieve better working efficiency and stability.
