Without specific Komatsu product documentation, it's difficult to determine the exact displacement precisely. However, for hydraulic piston pumps used in Komatsu excavators like the PC200 series, the displacement is a crucial parameter. It could typically range from 100 to 200 cubic centimeters per revolution (cm³/rev). A higher displacement value allows the pump to move more hydraulic fluid per revolution, which is essential for powering functions such as boom lifting, arm movement, and bucket operation in these excavators.
Operating Pressure
Rated Pressure: These pumps are designed to operate at high pressures to meet the demanding requirements of excavator operations. The rated pressure for the 708-2L-00460 and 708-2L-00300 pumps is likely to be in the range of 280 bar (28 MPa) to 350 bar (35 MPa). This pressure range enables the pump to stably supply power to the hydraulic system, driving various hydraulic actuators effectively.
Maximum Pressure: The maximum pressure that the pump can withstand in a short period is usually higher than the rated pressure. It may reach around 380 bar (38 MPa) to 420 bar (42 MPa), depending on the design and application of the pump. When the excavator encounters sudden high loads or extreme working conditions, the pump needs to handle such high pressures briefly.
