CTEL has come up with a coating for metal parts that is harder than chrome plate.
CTEL says it extends by up to six times the working life of extrusion dies, tools and components.
Added benefits were also gained from the system during the machining stage.
Water would be pumped at rates of up to 1.8 m³/s.
The clutches are available in sintered and cermetallic versions.
Alpha has produced a smaller twin plate clutch measuring 140mm.
