Common failures & inspection points
All pumps must undergo factory pressure testing at manufacture (typically 1.5x operating pressure). Documentation of these tests is required.
Inspection for scratches, pitting, or play in the internal tooth flanks and bearing surfaces. Tooth flank play should be within specification limits. This is critical for long service life and leak control.
Visual inspection of shaft seal (Packing Seal or Mechanical Seal depending on model). Inspection for oil/fluid leakage traces or damage. Particularly critical for sealless mag-drive models (8123A/8124A).
Test pump under typical operating conditions (rated pressure, rated speed). Abnormal vibrations or noises indicate internal damage or unbalanced impellers.
For marine applications: stainless steel models (127A/227A/327A/4227C) inspect for surface corrosion or stress corrosion cracking. Cast iron models require protective coating inspection.
