Features & Benefits
  • The WX is a horizontal multistage, radially split, ring section pump with centerline mounted between bearings (BB4).
  • The tie bolt construction permits rapid assembly and disassembly for maintenance purposes.
  • Individually balanced impellers are mounted in-line (tandem) on a generously proportioned shaft, individual keyways are provided for location and drive purposes.
  • Each stage element is made up of channel ring and diffuser, with O-ring seals to prevent external leakage.
  • The axial thrust experienced during operation is controlled by a close clearance balance device located at the discharge end of the pump after the last stage impeller.
  • Standard top/top suction and discharge flanges ensure that the pump is inherently self venting.
  • For exceptionally low NPSHa applications, WX pumps can be fitted with an inducer.
