GRAPHALLOY at the Houston Pump Symposium

Graphite Metallizing Corporation, manufacturer of GRAPHALLOY® bearings and bushings, will be exhibiting at the 28th Annual Pump Users Symposium in Houston, TX. This symposium will be held at the George R. Brown Convention Center from Monday, September 24 through Thursday, September 27.  

Engineers from Graphite Metallizing will be available to discuss the success of GRAPHALLOY, a graphite/metal alloy, in difficult pump applications. GRAPHALLOY® self-lubricating wear parts keep pumps from seizing during dry-run, low-flow, start-up, slow roll and shutdown. These are conditions that cause metal to metal pumps or plastic wear parts to fail, sometimes catastrophically.

GRAPHALLOY® wear rings and bushings operate at longer intervals without the need for replacements or maintenance which helps reduce downtime and maintenance expenses. In addition, GRAPHALLOY® operates successfully in temperatures from -400°F to +1000°F (-240°C to 535°C).

If you have an application where service and maintenance tasks are cumbersome or difficult to perform, speak with a GRAPHALLOY® representative at Booth #1715.

GRAPHALLOY® Self-Lubricating Bushings Will Not Seize

The environment in a rubber curing autoclave is 300ºF (150ºC) and has live high pressure steam. The grease-lubricated roller bearings were failing due to high heat and moisture,  causing interruptions in production. When a bearing failed, production was stopped due to the short shelf life of uncured rubber. 

GRAPHALLOY® bushings were installed and, after more than one year, there has been no production interruptions. If replacement is necessary, it can be done during scheduled outages because self-lubricating GRAPHALLOY will not seize the shaft.
