Common failures & inspection points
Rotor-to-rotor and rotor-to-housing clearance dimensions checked with dial gauge and compared against OEM wear limit values (measurement with gauges to be performed)
Mechanical shaft seal and gasket tightness inspection: check for leaks, cracks, discolouration or hardening; inspect wear of seal ring surfaces
Housing bore, rotor surfaces and cover plate for scratches, corrosion pitting or surface wear inspection (check cleanability)
Inspection of bearings and bearing clearances: radial clearance and axial clearance checked with suitable measuring instruments; note any wear and heating
Pressure relief valve and overpressure protection functional test; check setting values against manufacturer specification
Suction strainer and inlet filter inspect for contamination and blockage; monitor pressure drop across filter
Operating noise, vibration and unusual sounds diagnose (indication of internal wear pattern)
Fastening elements, fastening bolts and coupling alignment check; pump-motor/drive alignment re-measure
