Pumps are complex fluid-flow systems that are designed and calculated by specialists with exceptional hydraulic knowledge.

All the more bizarre if one uses "brushes and spatulas to optimize" their function. Let us summarize which technical parameters have to be kept in mind for such a protective treatment:

• Smoothness & Uniformity
• Abrasion resistance
• Anti-cavitation behavior
• Impact and shock resistance
• Corrosion-free (above and below the coating!)
• Positive influence on efficiency (low coefficient of friction)
• Minimum weight/density (+/- 1.0) to save energy
• Non-stick properties
• Repair and overcoating capability
• Ecological harmlessness

An impressive spectrum - and still not quite complete. If your previous measures cannot give a clear "YES" at every point - then you should read on here!
