Our Industries

Oil & Gas

In oil and gas applications, reliability and safety are essential. To support the industry’s highly regulated, mission-critical operations, John Crane offers a wide range of innovative services and applied engineering solutions.

Our experienced sales and engineering staff help select, design and apply sealing systems for even the most challenging conditions, and John Crane products meet the highest industry standards for containment of fugitive emissions.

We also have 90+ test rigs available to ensure components can operate with maximum reliability when subjected to specific environmental conditions. And with more than 200 global rapid-response locations, assistance is available whenever and wherever our customers need it.

Power Generation

Power generation plants vary greatly across the industry, from those fueled by coal or natural gas to those powered by nuclear, hydroelectric or geothermal energy. But though they operate differently, they still share a common goal: to meet the growing demand for energy in a responsible, efficient way.

John Crane’s depth and breadth of applied engineering expertise, product innovation and reliability services help plants of all types increase uptime, reduce emissions and improve efficiency to achieve all of their goals.

Chemical

Though the wide range of equipment required by the chemical industry poses a challenge, it’s one well met by John Crane. We have hands-on experience with virtually every style and standard of rotating equipment, and we’ve developed a broad range of solutions with proven application success:

  • Cartridge seals and support systems that meet global standards
  • Products for use on non-metallic or glass-coated equipment
  • Seals in exotic alloys that accommodate highly corrosive and abrasive applications
  • Innovative filtration of process flow to ensure required process purity
  • ATEX-compliant
  • FDA-recognised seal faces and elastomers Plus, our 200 global rapid-response facilities ensure that our chemical industry customers are never far from service, repair or support.
Pharmaceutical

As an innovator in applied engineering, John Crane is well equipped to address the unique and challenging requirements of the pharmaceutical industry. We engineer our products to meet the industry’s safety and reliability standards — as well as local environmental regulations — so that our chemical processing customers can increase their uptime and lower their license fees.

From clean-in-place components to batch documentation and certification of material integrity, John Crane provides pharmaceutical processing companies with the engineered components and services they need.

Polymers

Polymerisation is the first basic step in plastics production. Depending on the monomers, it can be carried out in bulk, in a solution, or in an emulsion. If monomer solutions are introduced into the reactor, they are first filtered to separate impurities.

Filtration is also used after polymerisation to recover monomer residues from polymer solutions/suspensions and to return them to the polymerisation reactor. Thermoplastics are an important class of plastic raw materials, like polyamide (PA), polymethyl methaycrylate, polycarbonate, or polyether ether ketone (PEEK).

After polymerisation, these materials are either directly granulated for further processing elsewhere, or they are directly melted and processed by extrusion or injection moulding. Our screen changers and melt filter systems are used in this stage.

Mining and Minerals

With decades of experience serving the mining and minerals industries, John Crane understands the need for greater equipment reliability and maximum performance in harsh environments.

To solve these challenges, we engineer application-specific components and offer a wide breadth of services aimed at reducing maintenance costs and lowering total cost of ownership. Our 200+ rapid-response facilities provide comprehensive repair and support services across the globe.

Food & Beverage

To achieve optimal efficiency while meeting stringent health and safety standards, plants and manufacturers in the food and beverage industry have to maintain a complicated balancing act. John Crane makes it manageable by engineering reliable, specialised components that both improve productivity and eliminate contamination.

From food processing plants to bottling, brewing and distilling plants, our products can withstand the challenges of any environment to consistently perform as expected and adhere to international HACCP standards.

In addition to reducing overall operation costs, John Crane products also aim to reduce the environmental impact of food and beverage processing by helping plants adhere to emissions regulations. Our process-specific components are engineered with the proprietary materials and clean-in-place designs needed to preserve nutritional standards and tolerate rigorous cleaning protocols.

Pulp & Paper Processing

In the pulp and paper processing industry, efficiency and reliability are key to controlling expenses because they help reduce the amount of energy required by critical processes. John Crane maximises both — and helps companies meet strict pollution regulations — with engineered components and seal support systems that limit emissions, tolerate high temperatures and reduce water consumption. Plus, our 200+ rapid-response facilities can also minimise unplanned downtime by providing service, repair and support worldwide.

We deliver proven mechanical seal technologies and services that improve manufacturing performance through:

  • increased operational reliability
  • improved equipment uptime
  • fewer maintenance interventions
  • reduced seal water usage
Refrigeration Compression

From oil refineries to petrochemical plants, many mission-critical operations require refrigeration for temperature-specific processes. As crucial as refrigeration compressing is to these applications, it is essential that every compressor seal and coupling maintains optimal performance and reliability.

With John Crane products, customers can not only achieve maximum efficiency in low-temperature applications; they can also reduce energy consumption and meet strict environmental standards for hazardous materials such as industrial refrigerants.

Wastewater and Clean Water Management

The high volumes and abrasiveness associated with wastewater and clean water management pose a significant challenge when it comes to designing the supporting equipment. Because the ratio of water to abrasive material from a single source can change frequently, every component has to be durable enough to withstand extreme abrasiveness and still perform reliably.

That’s where John Crane comes in. Our products provide cost-effective solutions that reduce energy consumption and increase the efficiency of equipment used in all types of clean water and wastewater applications, from filtration to chlorination.
