Self-lubricating material keeps pumps running

MAT-240 has been successfully trialled in mixer seals featuring a dry nitrogen barrier, where no other carbon or graphite material was able to provide protection without the presence of polar gases. The material has also been proven to be suitable for methane gas, steam and air applications, including the most demanding dry applications across a temperature range from -150 to +230°C.

"Extensive internal testing has shown that the coefficient of friction of MAT-240 is less than half that of other comparable materials, meaning it offers significantly improved wear resistance. Additionally, when running in dry nitrogen, MAT-240’s friction values are again proven to be less than half the values of typical carbon and graphite materials. These properties help keep pumps and seals running for longer than has previously been possible in dry and other challenging operating conditions, maximising uptime and reducing replacement costs,” commented Michael Ritter, Morgan Advanced Materials.
