: Since a bit long time, BFW pumps are expierncing high corrosion/errosion, specially at the last three stages. Has any one pass through same problem, and what could be the resons. By the way, lately, pump internals have been upgraded from Carbon steel to Stanless Steel, but, that only helped in defering the pump overhauling time duration.
Sounds like possible cavitation. Check NPSH required and available using empirical formulae.
