Common failures & inspection points
Verification of available and required NPSH against datasheet specifications; control of suction conditions and piping design; measurement of static and dynamic pressure at suction line
Verify housing material (stainless steel duplex/super-duplex vs. carbon steel) against operating fluid; perform corrosion testing per ASTM G48 or equivalent; check wear parts (wear rings, seals) for saltwater resistance
Vibration measurement (ISO 20816 or ISO 10816) at rated speed and load; check impeller balancing (ISO 1940); monitor bearing temperatures and clearance; test for wear on wear rings
Check condition of mechanical seals or labyrinth seals; measure leakage flow; control for corrosion on seal faces; inspect pressure relief systems for seawater/freshwater applications
Flow and pressure measurement during operation; compare with manufacturer curves; control for wear ring wear; check for cavitation phenomena or backflow indications; verify efficiency against specification
