Power Transmission CouplingsMetastream couplings have now become the firstchoice of many of the world's leading companies.Today, John Crane’s policy of constant innovationand product development serves to ensure thatMetastream couplings continue to satisfy thechanging demands of the market while complyingfully with the relevant industry specifications.

Seal Support SystemsMaintaining the correct operating environment iscritical if any seal is to operate at its optimum level.With this in mind we offer a comprehensive selectionof engineered pressure reservoirs, gas seal controlpanels, heat exchangers and abrasive separators.

Metastream flexible power transmission couplingsare designed for applications where the shaft endsare nominally 'in line'. High-speed applications arewell served by the couplings high torsional rigidityand natural balance features. Each Metastreamcoupling incorporates spacer retention anti-flyfeatures, plus an all-metal construction thateliminates the need for lubrication and maintenanceand ensures minimal downtime.

Mechanical PackingsMechanical packings have been an important part ofour product portfolio ever since the creation of JohnCrane in 1917. We have since pioneered the use ofnew manufacturing processes, different materialsand innovative braiding styles to produce superiorpackings for all types of challenging applications.
