Q1: What is the main function of the "DR" control?
A: The DR control is a pressure compensator. It automatically adjusts the pump's swashplate angle (displacement) to maintain a constant preset system pressure. When system pressure reaches the DR setting, the pump de-strokes to near-zero flow, reducing energy consumption and heat generation. It is ideal for systems with long holding periods.
Q2: What does the "VPA14N00" suffix indicate?
A: This code defines the mechanical configuration:
V: FKM (Viton) seals, suitable for a wider range of fluids and higher temperatures than standard NBR.
P: Standard parallel key shaft (DIN 6885).
A14: Port size code 14 (metric threads) on the A side (rear).
N00: No through-drive capability (solid shaft end).
Q3: Can this pump be used as a motor?
A: No. The A10VSO series with DR control is designed specifically for open-circuit pump applications. It is not recommended for use as a hydraulic motor.
Q4: What is the purpose of the X port?
A: The X port is the external pilot port for the DR pressure control valve. It can be used to:
Remotely set pressure: Connect an external relief valve to control the pump's pressure setting remotely.
Unload the pump: By depressurizing the X port, the pump can be forced to zero pressure for unloading.
Q5: What are the key differences between A10VSO and A2FO series?
