The repaired equipment was inspected in 2009 and showed no signs of corrosion or erosion. The Belzona system allowed full sealing on the previously corroded seal faces. Cost of these repairs is minimal in comparison with new equipment that would cost 80.000 €. A Testimonial letter from customer is available.
