Casings  -  Protective coatings

Scope of application

Seawater pumps
Thick matter pump
Heavy, solid pump casting – and never- theless often corroded, leaking or even worn after a short time. Unfortunately this phenomenon is quite common in many industrial and municipal applications and happens on a daily basis. Abrasive additives or a high solid content reduce the life-time of pump casings considerably. Chilled casting, stainless steel or other special materials rarely represent a pre- ferred solution owing to financial reasons. Due to the fact that many materials are difficult to repair and cannot be welded, many operators are afraid of using them.

KSB Pumps - and the winner is . . .

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 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.
