GRAPHALLOY®
Bearings For Wastewater Applications

GRAPHALLOY® is ideally suited for submerged applications such as wastewater. For one manufacturer, "the ability of GRAPHALLOY Bearings to provide trouble-free underwater operation without any lubrication" had been a key factor in the success of their products.

Bearings for success in wastewaterGRAPHALLOY provides unique advantages because it combines the properties of graphite and metal. The graphite structure can be compared to a deck of cards with individual layers that are able to easily slide off the deck. This phenomenon gives the material a self-lubricating ability that is matched by no other material. External lubricants such as grease or oil are simply not necessary. It will operate submeged and will not swell or lose it's lubrication. Graphalloy can be provided as direct replacements for industry standard pillow or flange block assemblies, or as custom bushing sizes to fit your equipment.Submerged wastewater application

 

Graphalloy bearings have been successful in the following applications:

  • Wastewater Treatment Plants (WWTP)
  • Wastewater Treatment Systems
  • Rotary Screens
  • Mixers
  • Pumps
  • Wastewater Treatment Aerators
  • DAF (dissolved air flotaion) Wastewater Sytem
  • Wastewater Filtration Systems

Successful Graphalloy Applications for Wastewater

WWTP Flocculators (Potable Water Process)Flocculators

Paddle wheels stir the incoming river water to keep the solids suspended until the water is sent to the clarifier. The paddles are mounted on long horizontal shafts through pillow block bearing assemblies. Bearings are fully submerged. Standard Pillow Block Bearings (cast iron pillow blocks with roller bearings) are replaced with self-lubricating GRAPHALLOY.

Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. GRAPHALLOY is used in bottom bearing and various pillow-block assemblies.
