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.
We have a solution for problems with lifetime on impellers by means of protective coatings! Scope of application: Open impellers Closed impellers Single-blade / multiple-blade impellers Non-clogging impellers Screw impellers Rubber / Polyurethane impellers 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 absorb destructive impact energies through permanently elastic material behavior. Layer thickness is adapted individually to the stress parameters and flow conditions of pump construction. This usually results in 5-6 times higher life-times for impellers coated with MetaLine in comparison with unprotected grey-cast iron constructions. Dependent on the actual impeller size, coatings up to rotational speeds of approximately 1.500 rev/min. are recommended. The solid content of the feeding medium may amount to far above 50 %. Constant liquid temperature should not exceed 60°C on average, however. Recommended for saltwater (offshore) applications.
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.
