Cost effective repair systems

Many of our repairs offer the ability to salvage equipment and restore them to new condition:

• Rebuilding Wear-Ring Seats
• Repairing holed or cracked casings
• Restoring cutwaters
• Reforming flange faces

These are all common repairs done to pumps, and are not an option with traditional repair techniques. Maintenance worker or engineer, who utilizes these techniques, will have much lower repair costs on their pumps (less than 50%) and a far lower occurrence of purchasing pump replacements.

Smoothing Pitted / Corroded Surfaces

Any cast-iron pump that has been running in water (95% of all pumps) will corrode and develop a pitted surface on the casing. This is the cause of the efficiency loss in most cases. Traditional pump shops have no solution to address this issue. This in fact is the greatest factor in restoring pump efficiency, up to 20 efficiency points to the operation performance.

Protective Coating

Not only can Belzona restore a pump to like new condition, it can also extend the life of a pump by preventing damage caused by fluid flow. The hydrophobic coating provides a much more efficient surface, especially when compared to that of a corroded casing effected by either rust, scale, or contamination build up.

Efficiency Enhancement

• Performance gains range from 7% on new pumps to 40% on those in service
• Reductions in operating costs can be realized immediately
• Pumps protected with Belzona systems are certain to last longer
• Belzona systems resist the damaging effects of erosion/corrosion, abrasion, and chemical attack that destroy cast iron, steel, bronze, and other materials of construction
• Worn pump components can be easily rebuilt and/or coated at much lower cost when compared to direct part replacement
• Ability for refurbishment of scrap components with minimal downtime
