Heavy cast pump casings and volutes are continuously exposed to abrasion, high-solid slurries, turbulent flow and cavitation stress. These conditions lead to premature material loss, hydraulic inefficiency and increased maintenance costs.
MetaLine elastomeric coating systems provide energy-absorbing surface protection that significantly extends service life while maintaining the original hydraulic geometry of the pump housing.

The elastomeric MetaLine coating technology is the great winner of the "KSB® Pumps (Germany) coating test".
In comparison with about 25 international competitors, our energy absorbing material process has established itself with an up to 35 (!) times higher wear resistance!
As the only (!) synthetic coating at all, MetaLine has been classified by KSB® as "... a functional cavitation protection ..."! The erosion resistance was even rated twice as high as the special alloy "Noridur" from KSB®!
The reason for this performance advantage lies in particular in the fact that we rely on energy-absorbing (soft) rather than energy-deflecting (hard) surface properties. This is a great success, but it comes at a price: simply “brush on by yourself” will not lead to success. It is a multi-stage process that must be applied by trained hands!
MetaLine – Protective coatings in use

MetaLine Series 700 – |
MetaLine Series 700 coatings optimize pump efficiency owing to their elastomeric very smooth, flow-optimized surfaces. Efficiency increases of more than 3 % are even possible with new housings. Service life extension (wear protection optimization) compared to FE materials amounts up to 500 %, compared with NON-ferrous materials (stainless steel) up to 150 %! Basically, the coating serves as a wear layer to protect the original material and especially its static behavior. This wear layer may be renewed if needed for a low cost. However the housing's original strength and geometry remains fully intact. A special form of cost optimization is the repair of pump half-shells made of rubber. Here, with minimal effort, existing change parts can be fully regenerated again. The cost savings compared to new parts procurement are significant.
