416 Stainless Steel Shaft is ground in steps to minimize stresses. It is then stress relieved in the vertical position to prevent warping.

Precision Cast Chrome Steel Impellers are secured to the shaft with keys and a shrink fit against a shaft shoulder.

Serrated Impeller Running Fits reduce the effects of rotor contact during system upsets or turning gear operation.

Suction and Discharge Nozzles can be provided in numerous configurations to accommodate plant piping layouts.

Robust Bearing System uses split sleeve tri-land hydrodynamic radial bearings to support radial loads. Axial loads are carried by pivot shoe thrust bearings.

Full 360-degree bearing housings are used (omitted: "on the CN pump") for added rigidity.

Advanced Sealing System is a controlled leakage design that employs a fixed serrated bushing over a straight shaft sleeve at each end of the pump.
