Industry: Pulp and Paper Manufacturing
Associated Products: Titanium Putty

Problem:
This fly ash pump would receive extreme wear from processing a slurry of burnt hog fuel (wood chips) and water. The wear was so sever that the pump was replaced every 3 months. Equipment replacement cost was estimated to be $35K.

Solution:
Complete housing was sandblasted to a SSPC-SP5 white metal finish. Flat expandable metal was tack welded in a raised position .065" above the actual substrate. Tack welding expandable metal improved mechanical bonding properties of Wearguard Fine. The housing was then sandblasted a second time to remove weld slag. The casing was thoroughly cleaned with Cleaner Blend 300. Titanium Putty was applied to the flange area rebuilding the missing metal. Wear Guard Fine Load was applied to the volute to a thickness of 1/2". Wear Guard Fine Load was pressed through the expandable metal, achieving complete contact to the housing. Wear Guard Fine Load was smoothed, contoured and feathered using acetone as a thinning agent following gel point.
