FAQ


QWhat are early signs of K3V280 pump degradation?
A: Reduced digging force, slow response during multi-action work, pressure fluctuation, and hydraulic overheating.
 
QWhat must be verified before installation on EX1200 series machines?
A: Hydraulic oil condition, coupling alignment, suction line sealing, and system pressure stability.
 
Q: Is this suitable for continuous mining operations?
A: Yes, it is designed for ultra-heavy duty environments with long operating cycles.
 
Q: Why is full hydraulic system stability critical in large excavators?
A: Because instability affects all machine functions simultaneously, reducing productivity and increasing mechanical stress.
