Fluid End Blocks

North America's leading supplier. 

Superior Steelmaking

Fluid end quality begins with high quality steel. ELLWOOD leads the industry with two modern steelmaking facilities with the capability to produce carbon, alloy and stainless grades with tight tolerance steel compositions. Steel scrap is melted in ultra-high power electric arc furnaces and then refined using advanced ladle metallurgy. Vacuum degassing and vacuum oxygen decarburization (VOD) processes assure optimum steel cleanliness.
