Reliable Main Hydraulic Pump and Regulator Options on makinateklif.com
The main hydraulic pump and regulator form the variable displacement group feeding every movement on an excavator. Falling flow shows first as longer cycle times, then as power loss under load.
What to Check Before Buying
- Model and variant code: different pumps may be used at the same tonnage
- Flow and pressure test report: the only proof of remaining performance
- Regulator and electric proportional valve: provide engine load control
- Oil analysis and suction filter condition: reveal the root cause of pump failure
Renewing the hydraulic oil and all filters when changing a pump stops residual debris destroying the new unit.
