Loctite® Manufacturing Reliability Gives Maintenance Team The Know-How.

An upper Midwestern paper mill operates several multifuel boilers for power and steam generation; the primary fuel being coal. Natural gas is also used to fuel the boilers when the coal supply is exhausted or interrupted. The switch-over process from coal to natural gas is expensive due not only to the cost of the fuel, but also since it requires the shutdown of parts of the paper manufacturing operation.

Cutting the expense in half while producing a quieter-running, longer-living assembly.

On sleeve bearing pumps, normal procedure dictates that they be hardened and ground to achieve long life. Hardening tends to warp a shaft, and where long warped shafts have to be corrected by grinding, tremendous expense can be experienced. Once warpage has occurred, key fitted ends and impeller threads can never be economically corrected. One of our customers decided to put an end to this expensive operation and chose a new approach using Loctite RC 609 retaining compound.
