Corrosion prevention for pumping brackish ground water
Corrosion prevention for pumping brackish ground water
(OP)
Hi All, I work in the pump rental industry, and I am designing a new pump that will be used for pumping ground water out of a construction site. This particular pump will be used in coastal areas (i.e. Florida) where the gound water could be brackish. The pumps we are using now have carbon steel components, and we are obviously having corrosion problems with these parts. What types of materials would be best to use that would be both cost effective and be resistant to cloride corrosion cracking and other seawater based corrosion? Water temperature would be ambient, 50-70F.
Thanks,

Pump casings..................Ni-Al bronze
Impeller, shaft, shaft sleeves (if fitted), and wear rings are preferably one of the super alloys like monel.
Having worked with pumps manufactureed with these materials, I woulg highly recommend them. Almost trouble free for many years, providing the pumps are started up and shut down correctly. Even then the major maintenance is replacing wear rings if correct running procedures are not adhered to.
