Radially Split Pressure Casings are positively located by interstage rabbet fits, ensuring overall pump concentricity and rotor alignment. Non-shear, compression-type O-rings positively seal channel rings.

Precision-cast Diffusers create symmetrical passageways around the impellers to equalize radial loads, resulting in increased bearing, wear ring and seal life plus tolerance to transient conditions.

Heavy-duty Rotor with short bearing spans minimizes deflection and prolongs bearing and seal life. Tight tolerances and precision fit impellers ensure proper clearance, concentricity and runout.

First-stage Impellers may be single- or double-section design, depending upon NPSH available.

Self-adjusting Flanged Balance Drum eliminates residual axial thrust across the operating range.
