Failure Symptoms

Initial signs of a failing Pump Gp-Ps include sluggish hydraulic response and reduced lifting or digging power. If left unaddressed, the pump's performance will continue to degrade, leading to intermittent hydraulic system operation. Continued operation with a failing pump risks damage to other hydraulic components due to debris or lack of lubrication.

Installation Tip

Ensure the hydraulic system is thoroughly flushed and clean before installing the new pump to prevent contamination. Avoid overtightening mounting bolts, as this can distort the pump housing and cause premature failure.

Service Note

Inspect the hydraulic system's suction strainer and return line filters for any debris that could indicate internal pump wear.
