HPK centrifugal pumps are widely used in extreme wear applications. The key attribute is inner lining of all wet parts with elastic materials, such as polyurethane and rubber. These durable and long-lasting materials enhance pump’s internal resistance to stress and corrosion by chloride-bearing fluids. Another lining option is polymer cast CeramCarbide®, which provides a quantum improvement over a single metallic casing. This particular material can sustain solid particles up to 10 mm.
