Wear resistant coatings to increase pump volute lifetimes
Heavy, massive pump casting – and yet often leaking after a short time or already completely worn out. Unfortunately, not a rarity but a daily occurrence instead. Abrasive medias or a high solid content reduce the lifetime of pump housings considerably. Chilled casting, stainless steel or other special alloys rarely represent a preferred solution. Due to the fact that many materials are difficult to repair and cannot be welded, many operators are afraid of using them.
We have a solution for problems with costs on housings by means of protective coatings! Scope of application: Centrifugal pumps Spiral pumps Vertical inline pumps Axial split case pumps Sewage pumps Submersible pumps Seawater pumps Cellular wheel sluices Rubber semi-shells KSB Pumps in Test The elastomeric MetaLine coating technology is the winner of the pump coating test carried out by KSB Pumps (Germany). In comparison with 25 competitors our material technique with an up to 35 times higher wear resistance has won through! As the only (!) synthetic coating at all, MetaLine has been classified by KSB as a functional cavitation protection! The erosion resistance was even rated double as high as that of the KSB special material "Noridur"! MetaLine - Technical solutions in detail METALINE SERIES 700 MetaLine Series 700 coatings optimize pump efficiency owing to their very smooth, flow-optimized surfaces. Efficiency increases of up to 3% are even possible with new systems. Life-time extension compared with FE materials amounts up to 500 %, compared with NFE materials (stainless steel) still 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 required, at low cost. The casing's strength and geometry is maintained completely. Repair of rubber pump semi-shells enables a special form of cost optimization. Existing exchangeable parts can be completely regenerated with minimum effort and expenditure. Cost savings compared to purchase of new parts are considerably.
MetaLine Series 700 – MetaLine Series 700 coatings optimize pump efficiency owing to their 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 NFE 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.
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"!
