Features

  • The suction and discharge flanges are conforming to ISO 7005-2/PN 16.
  • Due to the back-pull-out design the complete bearing assembly including impeller and stuffing box cover can be dismantled without removing the volute casing from pipe system.
  • All impellers are balanced statically and dynamically according to ISO 1940 Class 6.3.
  • Axial thrust is balanced by wear ring/balancing holoes system
  • Horizontal, radially split volute casing type, single stage end suction centrifugal pump with enclosed impeller
  • Dimensionally complies with EN 733.
  • In addition to 29 basic size conforming with EN 733, there are 20 additional sizes
  • In standard production soft packed stuffing boxes are used.
  • Depending on customer requirement mechanical seals are available. In this case, pump Shaft is Always Stainless Steel.
