FAQ
Q: What symptoms indicate the HPV118 pump needs replacing on a ZX225-3?
A: Main circuit pressure falls below specification, all functions slow simultaneously, case-drain flow exceeds the OEM limit, and oil temperature rises faster than normal.
Q: Does the HPV118 pump include a matched valve plate?
A: Yes, this HPV118 assembly includes a new matched valve plate and rotating group, so the sealing interface is correct from installation.
Q: What other models does the HPV118 pump fit?
A: Cross-reference keywords HPV118 / HydraulicMain Pump / ZX225-3 Hydraulic Pump / Excavator Main Pump / Axial Piston Pump / Hydraulic Power Unit apply. Confirm your machine serial number with our team to verify compatibility with other models.
Q: How to confirm the HPV118 is the correct pump for my ZX225-3?
A: Match the pump model plate reading HPV118 and confirm the machine is ZX225-3. Provide pump and machine serial numbers to our team for exact confirmation.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
