The reason why impellers fail and do not perform to their standard expectations: A pressure difference, either on the pump body or on the impeller, causes CAVITATIONS. If not addressed as soon as possible, cavitation may lead to an impeller disintegrating. Small and hard particles (sand) that make contact with the impeller may result in gradual wearing down over time. And the most common reason is Corrosion which essentially eats away parts within a pump. It is a common incident for things above the ocean that's why Seastar solution will give you durable and reliable enough to last for a year or more. Impeller from Seastar Solutions gives us superb quality.
