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.
