Features & Benefits
  • 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 generously 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.
