Successful Bearings for LNG Pumps

GRAPHALLOY® bearings and bushings are used in many low viscosity pump applications to help eliminate operational problems.

Pumping fluids with low lubricity such as LNG and Natural Gas Liquids (NGLs) can be difficult for metallic bearings. The hydrodynamic film provided by these low lubricity liquids is unable to provide sufficient lubrication, which can lead to metal-on-metal contact, galling or seizing.  

Graphalloy has unique properties to address these issues.  It is non-galling and does not seize, which allows tighter running clearances.  It is self-lubricating and can protect the pump during periods of flashing or extended run-dry operation.

What is Silver Graphalloy?

Silver Graphalloy is an alloy of silver impregnated graphite. This material is recommended for many of the most difficult self-lubricating bushing and current carrying applications. It has been widely used due to its low and constant contact drop, extremely low electrical noise, and long life.  Although it is primarily an electrical contact and brush material, it can be used as a bushing material in chemical solutions which attack other lubricants or metallic bushings.
