Through our partnership with Metcar, Boulden supplies M-161 Babbitt impregnated carbon graphite and M-310 nickel impregnated carbon graphite materials for the pump industry. Boulden works closely with plant engineers to improve the reliability, efficiency, and safety of their machines. Metcar’s high-performing materials can help plant engineers solve pump problems over a very broad range of conditions including extremely high temperatures.

Metcar® Composite Materials

The M-161 and M-310 material grades are critical to the reliable operation of countless pumps in the utilities, oil & gas, and petrochemical industries. Carbon graphite is self-lubricating, so it can run dry in certain conditions without the need for grease or oil lubrication. Since there is no metallic attraction between carbon graphite and metal running surfaces, these M-161 and M-310 materials are not prone to galling or seizing, which is a known failure mode of other types of bearings.
