WXH Between Bearing, Radially Split, Multistage, Ring Section Pump
The WXH pump is a horizontal, radially split, high-pressure, ring section pump. It is particularly well-suited for boiler feedwater on large industrial boilers and in combined cycle plants where severe cycling operation is commonplace.
- Applications:
Descaling, Boiler Feed - Industries:
Power Generation, Primary Metals
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.
