PSVD2 – 13E: The nominal displacement is 13 cubic centimeters per revolution (CM³ / Rev). This relatively small displacement is suitable for powering the hydraulic systems of mini – excavators with lower flow requirements, providing precise control over the movement of the excavator's boom, arm, and bucket.
PSVD2 – 21E: Has a nominal displacement of 21 CM³ / Rev. This model offers a higher flow rate compared to the PSVD2 – 13E, which is beneficial for mini – excavators that require more power to handle heavier loads or perform more demanding tasks.
PSVD2 – 27E: The largest of the three models, with a nominal displacement of 27 CM³ / Rev. It provides the highest flow rate, enabling the mini – excavator to operate with greater force and speed, making it suitable for larger – sized mini – excavators or those used in more strenuous working conditions.
