Pump <strong>Repair</strong><br />
Titanium Putty<br />
29/3/85<br />
Smith College Power Plant<br />
Utility Power Generation<br />
Problem:<br />
The stuffing box area of this Bell <strong>and</strong> Gosset pump would receive extreme wear from a slurry<br />
combination of water <strong>and</strong> fly ash. Previous method of repair was to grind damaged areas <strong>and</strong> rebuild<br />
with gasket or packing material.<br />
Solution:<br />
Complete repair areas were s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Surfaces were chemically<br />
cleaned using Cleaner Blend 300. Small holes were drilled in stategical positions to establish a<br />
mechanical bond <strong>and</strong> anchor Titanium Putty. A dummy shaft was machined <strong>and</strong> used as a mold to shape<br />
bearing seat areas. Titanium Putty was mixed <strong>and</strong> applied to repair areas. The dummy shaft was coated<br />
generously with <strong>Devcon</strong>’s Release Agent <strong>and</strong> placed into position. Release agent must be applied for<br />
ease in part or mold separation. Following a full cure of Titanium Putty, (24 hours), the dummy shaft<br />
was removed.<strong>Repair</strong> areas were then lightly s<strong>and</strong>ed to remove leading edges. Pump was assembled <strong>and</strong><br />
returned to service.
