The nominal displacement of the PVD-1B-32P-11G5 piston pump is approximately 32 cm³/rev (cubic centimeters per revolution). Due to manufacturing tolerances, there may be a slight variation in the actual displacement from this value.
Pressure Rating
Rated Pressure
This pump is engineered to operate at a specific rated pressure. For the PVD-1B-32P-11G5 used in the mentioned excavator models, the rated pressure is typically in the range of 25 – 35 MPa (250 – 350 bar). However, the precise rated pressure should be verified from the official product documentation of the pump manufacturer, as it can vary depending on design optimizations and application requirements.
Maximum Pressure
The maximum pressure that the pump can endure for short durations is higher than the rated pressure. It might reach around 38 – 42 MPa (380 – 420 bar), but this value must be confirmed through the product specifications. Exceeding the maximum pressure can cause damage to the internal components of the pump, such as the pistons, valves, and seals.
