? Bearing assembly – a large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.

? Liners – easily replaceable liners are bolted, not glued, to the casing for positive attachment and east of maintenance. Hard metal liners are completely interchangeable with pressure molded elastomer. Elastomer seal rings back all liner joints.

? Casing – Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.
