Rated Pressure: The rated operating pressure of this pump is usually around 300 - 350 bar (30 - 35 MPa). This pressure rating is essential for driving the hydraulic cylinders and motors in the 312D2 excavator, enabling it to perform tasks like digging, lifting heavy loads, and maneuvering. It provides the necessary force to operate the excavator's various components effectively.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is typically higher than the rated pressure, often reaching up to 400 bar (40 MPa) or more. This additional pressure capacity allows the pump to handle sudden peak loads during operation, such as when breaking through tough soil or rocks, ensuring the reliability and durability of the hydraulic system.
