Corrosion in sump spaces can be minimized by preventing ethanol fuel or vapors, and water, from entering the sump by following best practices regarding maintaining sump and submersible turbine pump [STP] fittings. In many cases environmental factors make maintaining a dry and vapor free sump difficult. In these situations, Veeder-Root has multiple products to help neutralize the effects of corrosion.
As the relative humidity goes up, so does the likelihood of corrosion. This is especially true in-sumps where the added presence of ethanol vapors feeds into a corrosive environment to accelerate equipment deterioration.
