Common failures & inspection points
Visual inspection of journal bearings, bearing bushes, and gear tooth surfaces for scoring, pitting, and wear patterns. Measure clearances with dial indicators.
Hydrostatic test at 1.5x operating pressure to detect O-ring and shaft seal degradation. Check for oil seepage at all wetted interfaces.
Pressure relief valve bench-test at rated displacement and validate against nameplate maximum pressure specifications for the KP/KF series.
Measure viscosity stability at 40°C and 100°C per ISO 3055 using samples from circulation tests. Verify oil type meets DIN 51524 Part 2/3.
Run pump at rated displacement and speed, measure sound pressure level at 1m and analyze vibration spectrum using accelerometers. Compare against marine noise class limits.
