Converting an
Impco ┬« 122  Circulator from the standard bearing housing design to a more functional and reliable pillow block bearing design can enhance the functionality and life cycle of the circulator.  
Here are the advantages to the pillow block bearing design: 
  • Better protection of the bearing seals
  • Eliminates the possibility of moisture inside the bearing housing which causes rust and can lead to bearing failure
  • If the bearings do become worn replacing them using the pillow block design is much easier, convenient and more cost effective.
