Belzona® Preserves 60-Year-Old Water Pump For Irrigation District



Local Authorities & Municipalities (LOMU)



Centrifugal Pumps (CEP)


Customer Location:

Arkansas, USA


Application Date:

May 2015


Application Situation:

The case and fits of a 60-year-old pump.



Flanges on the split line, wear ring fits, and packing areas were severely corroded, preventing the pump from sealing and made it very inefficient.



Belzona 1111 (Super Metal)

Belzona 1121 (Super XL-Metal)

Belzona 1341 (Supermetalglide)



Cast Iron


Application Method:

The application was carried out in accordance with modified versions of Belzona Know-How System Leaflets CEP-3 and CEP-5. Because of the severe erosion/corrosion damage of the wear ring fits and split line, 2"+ thickness of Belzona 1111 was needed. Because of this, self tapping screws/bolts were installed to provide stability to Belzona 1111. After 1111 was installed, all fits were machined. Belzona 1341 was coated on all wetted surfaces.


Belzona Facts:

The pump was approximately 60 years old. Lead time for replacement was 14 months. Welding was not an option because the substrate was cast iron. Pump needed to be back in service in a very short amount of time. No alternatives were available on such a short notice.
