Process VariationUnlike many industries, the processes within the Chemical and

Pharmaceutical industries are many and varied, often designed

to meet the needs of a particular product. Careful selection

and specification is vital to ensure the most appropriate

solution to meet unique sealing requirements.

Increased reliability is achieved on high solids applications with

the Type 2800EX cartridge seal, 670, 680 and GL1B metal

bellows or 5860 cartridge seals.

Heat Transfer Services present very predictable applications

with extreme product performance requirements. The John

Crane Type 609 metal bellows with grafoil or Type 2609 dual

metal bellows & grafoil cartridge seals were developed for a

broad range of heat transfer duties.

Polymerisation is a common source for rotating equipment

failure. Heat sensitive products or fluids, which solidify in the

presence of cooling liquid, have shown dramatic increases in

MTBR (Mean Time Between Repair) and uptime with the Type

2800 Series. The absence of frictional heat and cooling/flush

liquids eliminates the cause of polymerisation.

Challenging and unique applications such as high pressure,

high speed, Polymerising fluids, HF alkylation and aggressive

acids, high temperature fluids and de-watering applications

require experience and proven customised designs.

By eliminating liquid based support systems the Type 2800/E

ensures 100% product purity, provides non-contacting, dry

running capabilities on transfer services and therefore

dramatically reduces operating and maintenance costs.

The modular design of the John Crane 5600 family of cartridge

seals provides optimum flexibility and reduced inventory. This

design allows changes from single to double, from pusher to

metal bellows, from pressurised to non-pressurised all within

the same cartridge.

A full range of seal support systems are available for use with

double and dual seal applications.

Safety & Regulatory Compliance

Over the past two decades, environmental and safety control

has significantly reshaped the chemical processing industry.

John Crane has responded with Maximum Achievable Control

Technology, which delivers unmatched reliability improvement

and Operator Safety.

John Crane’s commitment to extensive materials research

has led to the development of the Type 48SC, a dry running

uncooled secondary containment safety seal designed to

provide emissions compliance with dramatically reduced

cost of ownership.

All the above features ensure the safest possible solution

during both normal operation and in upset conditions.

Type 2800 Series cartridge seals provide zero emissions

operation with added benefits of eliminating liquid barrier

systems and non-contact operation.

The tandem arrangement of the Type 48 inboard and spiral

groove secondary containment offer the safest engineered

cartridge seal ever applied.

Critical Plant Operations

product filtering and polishing is often a key driver in applying

non-contacting Type 2800/E seals.

Plant utility water and waste treatment divisions often present

unique application challenges. Frequently, applying seals,

which conserve or eliminate flush water such as the Type

2800EX, can reduce costs.

Specific John Crane designs are available for CIP/SIP. Smooth

profiles and fine surface finishes facilitate cleaning and

sterilisation. Novel designs providing quick-clean and proven

steam sterilisation techniques have been developed.

Product purity is a critical need both economically as well as

operationally. Maintaining product purity, the elimination of

Challenging rotor dynamics of mixer and agitator shafts often

present difficult reliability issues. John Crane’s mixer and

agitator seals use state of the art FDA materials, CIP/SIP

designs, which are tolerant of broad axial and radial shaft

movement and suitable for glass lined equipment.

Plant AvailabilityWith the demand for continuous improvements in plant

availability and output, John Crane are ideally placed to provide

direct operational improvements through rotating equipment

reliability initiatives aimed at increasing MTBR (Mean Time

Between Repair) and inventory rationalisation programmes.

Using Interface, John Crane’s Reliability Management Software,

the reliability of a single pump or an entire plant can be

monitored. This can be used to support any reliability initiative

from a simple repair programme through to a full Alliance,

where all aspects of equipment reliability are covered.

Product Innovation

materials research is evident in state of the art analytical and

performance laboratories throughout the world. In addition,

satellite manufacturing of a variety of carbon wear faces,

alpha sintered silicon carbide as well as PTFE and

perflouroelastomers have ensured a position of leadership

in the mechanical sealing industry.
