GRAPHALLOY^® Case Histories

These Case Histories provide an overview of how equipment designers use GRAPHALLOY materials to successfully solve problems with difficult applications.

Automotive Parts Production GRAPHALLOY bearings increased production in a high temperature furnace and gave them maintenance-free service.	Chemical Refinery Pumps In a chemical plant pump in heavy viscosity pumpage, GRAPHALLOY bushings increased the pump life by 6x and counting	Power Plant Dampers A switch to GRAPHALLOY pillow block and flange bock units solved seizing issues and costly maintenance on these dampers

Potato Chip Fryer GRAPHALLOY bearings in stainless steel pillow blocks have been "running strong for over 6 years" in a tough potato chip fryer application	Food Oven Conveyor GRAPHALLOY FDA Acceptable Bearings increased bearing life from two weeks to several years for a food oven OEM	Glass Plant GRAPHALLOY bearings helped save $250,000 a year for a glass manufacturer with a 500ºF application

Steel Plant A steel plant increased bearing life and eliminated grease safety issues by switching to GRAPHALLOY bearings	Mixers An industrial mixer manufacturer switched to GRAPHALLOY bearings, and solved their short bearing life problem.	NGL Pumps GRAPHALLOY is non-galling and self-lubricating. perfect to "combat low NGL viscosity", as mentioned in a Pumps and Systems article.

Pulp and Paper GRAPHALLOY bearings are corrosion resistant and can handle high temperatures, which solved a major paper company's problem application	Ammonia Pump According to one pump manufacturer, ammonia pumps fitted with GRAPHALLOY bushings can run dry for 24 hours with no wear	Green Energy GRAPHALLOY bearings have been used in various green energy applications, including to allow solar panels to slowly follow the sun

Pizza Oven Cam followers to keep a oven belt on track were constantly failing. GRAPHALLOY cam followers were installed and solved the problem.	Wastewater Application GRAPHALLOY bushing lasts 20+ years in waste treatment aerator at a Wastewater Treatment Plant. The bushing operated 40% submerged.	Fermilab Other bearings failed in the corrosive, radioactive "Nuetrino Target Adjustment" mechanism- GRAPHALLOY bushings succeeded

Biodiesel A company needed bearings for 1000ºF process of making biodiesel fuel out of wood chips and cooking oil. GRAPHALLOY bearings were the solution.	Condensate Pump GRAPHALLOY bushings increased a condensate pump MTBR to seven years, and showed minimal wear when they took it apart	Seafood Processing After switching to GRAPHALLOY bearings on a flash freeze conveyor for seafood, bearing life improved from one month to 5+ years

Subsea Hose GRAPHALLOY bushings were able to operate where babbitt-lined bushings could not- they are now specified for these underwater hose reels	Gypsum Board Dryer Oven The drag chain conveyor was failing due to high temperatures (550ºF). For GRAPHALLOY Cam Followers, this was no problem.	Boiler Feed Pump A boiler feed pump was constantly failing from dry running- switching to Graphalloy bushings allowed it to run dry and stopped failures

Oil & Natural Gas Field Flares Burning off volatile organic compounds protect the atmosphere- GRAPHALLOY bearings keep the control linkage system working	Molten Sulfur Pump Non-galling GRAPHALLOY bushings were able to solve vibration on molten sulfur pump by reducing running clearance	Ethylene Pump A refinery was able to save between $150,000 and $300,000 a year by switching to Graphalloy Bushings on a ethylene light hydrocabon pump

Thermoforming GRAPHALLOY bushings last 7+ years in a plastic thermoforming application	Conveyor with Washdown GRAPHALLOY bushings last years in a conveyor for deli meats, where greased bearings were failing due to washdown
