Precision Cast Diffusers minimize bearing spans, thereby increasing pump reliability and efficiency.

Suction and Discharge Connections can be located on the top or the bottom of the barrel and may be supplied with flanged or weld end design to suit installation requirements.

Forged and Hardened Stainless Steel Balance Drum is conservatively sized to completely unload the thrust bearing at all operating points.

Self-Aligning, Double-Acting Tilt-Pad Thrust Bearings are conservatively rated to carry axial loads that may be encountered during transient operating conditions.

Precision Cast Tandem Impellers are positively locked and keyed to the shaft.

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