Common failures & inspection points
Confirm actual port sizes match model designation (e.g., 3" = 75mm) and verify NPT or ISO thread specification against pump nameplate and installation drawing
Verify seal type installed (carbon/ceramic, silicon carbide, tungsten carbide faces) matches marine corrosion specifications; check lubrication method (grease-lubricated vs oil-lubricated) for saltwater/freshwater environment compatibility
Confirm pump nameplate rated head (e.g., 112 ft) does not exceed certification for actual discharge line pressure; verify pump curve performance at installed outlet elevation and slurry/density conditions
Document maximum particle size rating (e.g., 3" for T-Series, 0.63" for 80 Series); assess whether installed strainers (mesh size) align with pump inlet design to prevent impeller jamming in marine debris conditions
Verify automatic repriming characteristics under actual marine conditions (partially filled suction lines, high suction lift); confirm two-vane semi-open impeller design matches nameplate 'self-priming' claim for stated suction lift elevation
