What is the consistency of the conveyed medium? The range of applications ranges from tablet powder to sewage sludge. The corresponding coating material is available for every surface-contacting and thus abrasive or erosive solid.
Rotors are often galvanically chrome-plated. However, if the chrome plating is no longer sufficient or if other factors are in favour of a coating in the thermal spray process, then hard materials with a metal matrix, such as tungsten carbide or chrome carbide, are the first choice for thermal coating in the pump industry.
The decisive benefit of thermal coatings compared to hard chrome coatings lies in the wear behaviour. The hard chrome coating can lead to burr formation, which causes the stator to run in and destroy it in the long term. The thermal spray coating only runs in and thus protects the stator.
As specialists in surface technology in the pump industry, we can produce coating thicknesses from a few hundredths to several millimetres. It does not matter whether the coating of new parts, repairs for scrap salvage or maintenance work is involved.
