FAQ


QWhat symptoms indicate hydraulic pump wear in ZX160 machines?
A: Weak digging force, slow arm response, unstable pressure readings, overheating, and abnormal hydraulic noise are common warning signs.

 

QWhy does the excavator lose power under load but works normally when idle?
A: Internal leakage or reduced volumetric efficiency in the pump may cause insufficient pressure delivery during high-demand operations.
 
Q: What must be checked before installing a new hydraulic pump?
A: Ensure hydraulic lines are clean, oil is uncontaminated, filters are replaced, and coupling alignment is correct before startup.
 
Q: Can this pump operate in mining and harsh construction environments?
A: Yes. It is engineered for stable performance under heavy loads, dust exposure, and long operating cycles.
 
Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
