Sluggish boom lifting and weakened digging force indicate that your SANY excavator is suffering from internal pressure leakage inside the main hydraulic pump. When the A28VO130 rotating group drops its volumetric efficiency, multi-actuator coordination turns jerky, resulting in slower cycle times and inflated fuel costs on every job site. Do not let a worn power drive drain your field profitability on SY215, SY225, SY235 or SY245 excavation projects.

FAQ
Q: Fault Diagnosis: What operational clues indicate that this A28VO130 main pump has developed high case pressure?
A: Frequent extrusion of the front input shaft lip seal, excessive oil sweating at mating joints, and uncharacteristic foaming inside the hydraulic tank.
Q: Installation: What pre-cleaning steps are required when replacing the pump?
A: Field mechanics must flush the hydraulic lines with fresh cleaning solvent and replace the suction filter and pilot filter to protect the fine control orifices.
Q: Compatibility: Will this A28VO130 casing assembly replace the original without upgrading the chassis mount?
A: Yes, part number A28VO130 serves as a direct engineering match for the original pump fitted on SANY SY215, SY225, SY235 and SY245, ensuring direct drop-in setup compatibility.
Q: Extreme Environment Performance: How does the internal rotating assembly resist cavitation during cold sub-zero morning startups?
A: The wider internal suction port shapes optimize fluid intake speeds, eliminating cold oil restriction pockets and preventing vacuum scoring.
Q: What quality options are available?
A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
