Structural Features & Core Advantages
1. Integrated One‑piece Design: Main piston pump, solenoid valve and dual‑gear pump are pre‑assembled as a whole for easy installation and neat piping layout.
2. Electronic Load‑sensing Control: The solenoid valve accurately regulates flow and pressure to ensure smooth combined movements and comfortable operation.
3. Integrated Dual‑gear Pump: Supplies both pilot control pressure and system charging oil for quick power response.
4. High‑durability Wear‑resistant Structure: Valve plate and pistons are made of high‑strength wear‑resistant materials, suitable for heavy‑duty applications such as earthmoving and breaker operation.
5. Original Matching Performance: Pre‑calibrated for Takeuchi hydraulic systems, enabling direct replacement without complicated commissioning.
Typical Applications
- Main hydraulic power assembly for Takeuchi mini excavators
- Suitable for multi‑function combined operations including earthmoving, breaking and grapple work
Installation Notes
1. Recalibrate solenoid current and system pressure after replacement.
2. System filtration accuracy shall be no less than 10 μm to extend piston pump service life.
3. Ensure correct wiring of the solenoid valve to prevent damage to electronic components.
