Product catalog summary
Applications
  • Balancing of pump impellers in serial production.
  • Unbalance correction according to customer specifications, such as axial milling in the cover disc.
  • Alternative methods include axial milling or drilling on the cover disc.
  • Can be configured as a single machine (Audit) or combined with a correction station.
  • Loading options include manual, automatic with internal lifting table, or automatic with external gantry or robot.
Advantages
  • Fully-automatic operation cycle.
  • Unbalance detection and correction possible in one station.
  • No need for external handling units.
  • Compact and robust design.
  • Rotor type-specific calibration.
  • Flexible location selection and easy changeover.
  • High accuracy.
Description
  • Force measuring, vertical balancing machine for measuring and correcting unbalance in one or two planes.
