Limited Tenders are invited for Supply Of Sacrificial Zinc Anodes
The sacrificial zinc in the primer provides short-term protection to the exposed steel from corrosion through cathodic polarization, providing sufficient time for the silane to form an effective barrier layer.
Features include: stainless steel strainer, shaft, impeller, outlet and hardware for maximum corrosion resistance: mechanical seals in enclosed pressure compensated oil chamber; nitride hardened 410 stainless steel impeller for abrasive applications: tandem tungsten carbide/tungsten carbide and tungsten carbide/tungsten carbide mechanical seals; field adjustable nitrile rubber-lined diffuser/wearplate optimizes efficiency throughout the life of the pump; and equipped with sacrificial zinc anodes for maximum life in a saline fluid environment.
