Dealloying of a Nickel–Aluminum Bronze Impeller

2008/10/1A brackish water pump impeller was replaced after 4 years of service, while its predecessor lasted over 40 years. The subsequent failure investigation determined that the nickel–aluminum bronze (NAB) impeller was not properly heat treated, which made the impeller susceptible to aluminum dealloying. The dealloying corrosion was exacerbated by erosion, because the pump was slightly

Hard Iron versus Cast Iron Impellers for Non

Usually, a hard iron material is only required if your non-clog pump utilizes a semi-open impeller. A semi-open impeller does not have a shroud on the suction side and rotates against an adjustable suction wear plate, which results in a high amount of wear on the impeller.
