Wear resistant repair compounds for impellers in hydroelectric

Constantly in use, constantly stressed, and with little time for maintenance – the typical lifecycle of a Francis or Kaplan impeller. Even minor irregularities created on these precision blade surfaces lead to flow-induced turbulence that can trigger additional wear and tear. Instead of "stress-loaded" welding, alternative repair technologies should also be considered.

MetaLine Series 700 – Sprayable / OEM Manufacturer quality MetaLine Series 700 coatings absorb destructive impact energy and vibrations through a permanently elastic material behavior. The coating thickness is individually adapted to the load parameters and flow conditions of the turbine design. The particularly smooth surface structure prevents turbulence and is exceptionally cavitation-resistant. MetaLine Series XL – Trowel- or brushable / Repair quality MetaLine Series XL are low-weight, flat-coat or brush-on repair materials. They serve to recontour partial erosion states. Due to the completely temperature-free processing, no surface tensions arise. The materials are electrochemically neutral and do not lead to bi-metal corrosion. Installation does not require trained hands and can be implemented insitu without dismantling the runner.

Scope of application:

Francis impellers
Kaplan impellers
Pump impellers
Rotors
Water brakes

Composite coating – MetaLine KXL is a brushable protective skin which prevents metallic substrates from corrosive and abrasive impact
Cavitated Francis impeller before recontouring – this requires expertise
Worn blades on a Francis impeller – prepared for repairing with MetaLine Ceramic Repair Compound
After finishing and over-all coating with MetaLine Ceramic Repair Compound KXL applied with a brush – a new profile, a brand new life
Ceramic coating – MetaLine Series XL is the right tool for everyone who wants to repair things like that by himself. Who require more performance should investigate about the sprayable elastomers of MetaLine Series 700
Wear at the blade end of a Kaplan turbine in Austria
After aluminum oxide blasting – please, do not hesitate to contact us if you have any questions about blasting techniques. There is hardly any specialized area where substrate preparation is more important
During application of MetaLine Ceramic Repair Compound SXL – the hat tells you something about the application temperature – which was quite low
Ceramic Protective Coating MetaLine KXL – the unevenness is due to the casting surface profile, not the coating
