Abrasion resistant protective coatings to increase pump impeller lifetimes
Enormous centrifugal forces, colliding solids, variant liquid viscosities, elevated temperatures and aggressive chemical load – this is everyday routine for standard pump impellers. No wonder life expectancy has to be rather limited. Just like in ordinary life – with increasing age, the performance – better said the effectiveness – deteriorates rapidly.

MetaLine Series 700 – MetaLine Series 700 coatings absorb destructive impact energy through permanently elastic material properties. Coating thickness is adapted individually to the stress parameters and flow conditions of the pump design. This usually results in 4–5 times higher lifetimes for impellers coated with MetaLine compared to unprotected cast iron designs. Depending on the actual impeller size, coatings up to rotational speeds of approximately 1.500 rev/min. are recommended. The solid content of the pumped medium can be well over 50 %. Constant liquid temperature should not exceed 60 °C (140 °F) on average. Ideal for saltwater (offshore) applications.
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 KSB’s special alloy "Noridur"!
