The original design of the 1,000 H.P. pump frame was a steel fabrication. Converting to Ductile Iron achieved more uniform stress distribution, lower production cost and improved strength-to-weight ratio. The weight was reduced by 46 percent, which is particularly important for remote installations where the parts must be airlifted.

A camshaft thrust plate is exposed to severe abrasive wear. The reason for selecting Ductile Iron was to combine wear resistance with machinability.

For break-in, this casting is phosphate-coated.

Ductile Iron can readily by surface hardened to 55 Rc, which provides for the superior performance of this catch-sleeve.
