Corrosion can severely damage the casing walls of the volute. These can be repaired cost effectively in our workshops thus avoiding the need to purchase replacement parts.

VOLUTE AND IMPELLOR REPAIRS

Loss of pumping efficiency due to profile change caused by erosion-corrosion or mechanical damage.
Through advanced coating techniques we can restore :
 
  • Wear ring clearences

  • Rebuild Vane profiles

  • Back Vanes

  • Protect against corrosion and chemical attack
