All John Crane products benefit from our policy ofconstant innovation and product development. Thisallows them to satisfy the ever-changing demandsof the market while still complying with all relevantindustry standards and specifications.
Combining this extensive selection of products withthe type of customer-specific service programs youwould expect only from the genuine market leaderenables us to provide the right solution for any typeof sealing or associated requirement
A complete portfolio of productsfor rotating equipment
Mechanical SealsWe offer a wider range of mechanical seal productsthan any other manufacturer, all characterised byhigh-quality, innovative design concepts that helpreduce both installation and maintenance costs.
Dry Gas SealsJohn Crane has over 40 years of gas seal experienceon which to draw. Along with our intimateunderstanding of the sectors and applications inwhich these seals operate this has ensured that ourdry gas seals have become the accepted solution inmany different industries. They offer outstanding
John Crane is widely recognised as having the worlds most comprehensive product andtechnology portfolios for rotating equipment applications. With over 50 active patents onvarious product designs and systems, plus the ability to draw from a global sealing databaseof over a half-million successful applications, John Crane is clearly a world leader.
By combining advanced and thoroughly proventechnologies with industry expertise John Crane isable to offer the optimum mechanical sealingsolution for virtually any application.
versatility and are compatible with virtually any typeof gas. Pressures in excess of 200 bar, temperaturesup to 400oC and speeds up to 180 m/s can all beaccommodated, widening the range of applicationson which these seals can be used.
Power Transmission CouplingsMetastream couplings have now become the firstchoice of many of the world's leading companies.Today, John Cranes 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.

Water SystemsSince the early introduction of elastomer bellowsmechanical seals, John Crane has been the leadingsupplier to manufacturers building pumps forresidential, commercial, industrial, and agriculturalwater systems. As these applications become moredemanding, we continue to innovate with morerobust designs and improved materials to meet theneed for higher pressures, corrosion, and abrasion.
Commercial and IndustrialRangeFollowing the integration of two re-engineeredproduct ranges, John Crane introduces a new rangeof mechanical seals aimed at the high volumemachinery market.
We have taken proven designs updated themanufacturing techniques and also expanded therange of standard dimensions.
Materials used throughout are either of our ownmanufacture or sourced from companies known fortheir quality and proven over a number of years.
We have selected a standard range of materials thatmeet a very wide range of duties. Suitable forindustrial, commercial and residential watersystems, heating and cooling systems and pool &spa applications.
The new seals fit into a range of standard cavitieswhich cover the majority of the market requirements.
Refrigeration CompressorsJohn Crane pioneered the development of metalbellows seals for refrigeration compressors to meetthe demands imposed by new refrigerants and strictleakage controls on ozone-depleting gases. Today,our seals are fitted on the majority of newmanufactured compressors.
