Structure features
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. Throat bush – wear is reduced and maintenance simplified by the use of tapered.
