Material of construction for boiler-cleaning booster pump
May 8, 2012
Q. I'm quoting a booster pump for boiler cleaning application and what material should the pump be? I know Carbon Steel is a no go, what about SS316?
The Chemical Clean regime to which the booster pump will be exposed to have the following two principal steps with rinses in-between and afterwards:
- Acid Stage: 90éûô 10% Inhibited Ammoniated Citric Acid (pH 3.5)
- Copper Removal & Passivation stage: 45éûô 1% Ammoniated Citric with Hydrogen Peroxide.
Anyone with good advice welcome.
