Overview

Why choose Cast Iron?

Cast iron includes gray iron and ductile iron grades. For pump casings and other equipment housings, material selection depends on loading, fluid conditions, wall geometry, machined interfaces and the required inspection plan. The specified grade, applicable standard, casting route and acceptance criteria should be confirmed against each project drawing.
