Problem:
Exposure to pulp, H2SO4, and caustic soda would cause severe abrasive and corrosive damage to the
interior of this Ingersol Rand pump casing. The previous method of repair was to simply replace the
complete unit when required. Replacement cost was estimated to be 20K.
Solution:
The complete interior of the casing was sandblasted to a SSPC-SP5 white metal finish. All repair
surfaces were chemically cleaned using Cleaner Blend 300. A template was manufactured from wood
and positioned to resize bearing seat areas. Original evidence markings were used as a guide when
manufacturing the template. Devcon’s Release agent was applied generously onto the template. Release
Agent must be used for easy removal or separation of templates. Titanium Putty was applied to damaged
bearing seat areas rebuilding the missing metal. Ceramic Repair Putty was applied to all corroded areas
deeper than 1/4”. Following partial cure of Titanium Putty and Ceramic Repair Putty, (4 hours),
Brushable Ceramic was applied to a thickness of 30 mils. Brushable Ceramic encapsulated the repair
areas and provided a long lasting, chemical and abrasion resistant, low co-efficiency to friction surface.
Devcon’s repair cost was $2K.
