1. Bearing assembly: large diameter shaft with short overhang contributes to long bearing life.
2. Liners: Easily replaceable liners are bolted, not glued to the casing for positive maintenance.
3. Casing: Casing halves of cast or ductile iron provide high operating pressure capabilities.
4. Impeller: Front and rear shrouds have pump out vanes that reduce recirculation and seal contamination.
5. Throatbush: Wear is reduced and maintenance simplified by the use of tapered.
