Operating data, Characteristic Curves

ZMK - sectional drawing
  • Q= 10000 m³/h
  • H= 140 m
  • P= 25/40 bar
  • T= 150°C

Design features and properties

  • pump meets all requirements of API 610, type BB1, centre-line split, double-flow impeller, with bearings on both sides, radially split casing
  • centerline-supported
