Common failures & inspection points

Impeller blade wear and erosion from salt water corrosion

Visual inspection for pitting, surface degradation, blade edge rounding; measure blade thickness and compare against original specifications

Bearing degradation and lubrication breakdown in seawater environment

Check bearing clearances with dial indicators; verify cooling jacket flow rate and temperature; listen for abnormal bearing noise during operation

Mechanical seal leakage or cavitation damage

Inspect seal faces under magnification; check for crystalline deposits; measure current draw to detect cavitation inception

Cooling water jacket blockage reducing motor thermal management

Measure inlet/outlet jacket temperature differential; use thermal imaging to detect hot spots on motor case; flush jacket with fresh water and measure pressure drop

Galvanic corrosion between dissimilar metals in seawater circuit

Inspect exposed copper/bronze/steel surfaces for white/green corrosion; verify sacrificial anode condition (if present); check saltwater concentration via conductivity meter
