YUKEN A10-FR07C-12 Variable Displacement Piston Pumps
1. Model Explanation
The model YUKEN A10-FR07C-12 is a high-performance variable displacement piston pump produced by YUKEN, a world-leading provider of fluid control solutions. Each segment of the model has a specific meaning, which is detailed as follows:
- A10: Represents the pump series and rated pressure, with a rated pressure of 100 Bar (10 MPa).
- FR: “F” indicates the mounting type (flange mounting), and “R” indicates the rotation direction (clockwise when viewed from the shaft end, standard configuration).
- 07: Indicates the control method, which is remote control type (supports external remote pressure adjustment for flexible system control).
- C: Represents the pressure adjustment range, ranging from 7 MPa to 14 MPa.
- 12: Represents the design number of the pump.

3. Important Notes
- When setting the pressure, ensure that the full cut-off pressure does not exceed the maximum intermittent pressure (21 MPa) to avoid pump damage. For remote control operation, ensure the external control signal is stable.
- The pump features variable displacement adjustment, which can automatically reduce the discharge flow when the outlet pressure approaches the preset full cut-off pressure, helping to save power and reduce oil temperature rise.
- Contamination of hydraulic oil is a major cause of pump failure and service life reduction. It is recommended to maintain the oil contamination level within NAS 10 class, install a tank filter of at least 100 μm (150 mesh) on the suction side, and a pipeline filter of ≤ 10 μm on the return line.
- The pump adopts precision manufacturing technology and high-quality materials, ensuring excellent wear resistance and long service life. It is widely used in hydraulic systems of various industrial fields such as mining, chemical industry, ships, testing equipment and presses that require remote pressure control.
