Article on Graphite-Metal Bushings Success in a Heater Drain Pump

This past month, Pumps & Systems Magazine published an article on graphite-metal alloy bushings in a heater drain pump for a nuclear power plant. The switch to this self-lubricating, non-galling material increased the MTBR to 8 years! Read more here.

Graphite-Metal Alloy Bushings Solve Dry Running Issue with Raffinate Pumps

Raffinate is a gasoline additive to help meet scricter emissions standards. A pump company with a raffinate pump experienced a bushing failure- their PEEK bushing came apart and coated the shaft. They theorized that the failure was due to flashing/dry running. They found a solution that could handle a flashing/ dry running raffinate application- graphite-metal alloy bushings. Read more here.

Graphite-Metal Alloy Bushings Successful in Screw Compressor

In this particular application, Graphite-Metal Alloy Bushings are used in a screw compressor in hydrogen gas service.  It is a high speed, low load application for the bushings.  They had originally tried aluminum bushings, which failed, then plain bronze bushings, which also failed.  They then tried Graphite-Metal Alloy Bushings, which have been successful in this application.  Read more here

Graphite-Metal Alloy Miniature Bushings for Semiconductor Wafer Manufacturing

These miniature bushings allow for linear movement in a slide carriage in the production of semiconductor wafers.

These tiny bushings highlight the ability of the graphite-metal alloy material to meet extreme design requirements (this bushing’s outer diameter being not much wider than the year on a penny).

Carbon Capture (and where Graphite-Metal Alloys come in)

Carbon capture is in the news recently (read more here) and this involves the pumping of CO2.  Similar to light hydrocarbons, CO2 is low lubricity and therefore creates problems for metallic wear parts that depend on the lubricity of what is being pumped.  Graphite-metal alloy bushings are non-galling and self-lubricating, thereby allowing these pumps to survive contact between the stationary and rotating parts and even flashing and

Pizza Magazine Highlights Graphite-Metal Alloy Bearing Solution

 An old oven was at the heart of popular Lino's Pizza & Italian Restaurant in Rockford, Illinois, but constantly maintaining and replacing the bearings was causing tough work and costly downtime.  They found self-lubricating, maintenance-free graphite-alloy bearings eliminated the maintenance and the downtime, and could handle the oven's high temperatures.  Read the article here: https://www.pmq.com/linos-pizza-oven/
