TYPE
In the event of an operating problem the machine must be switched off
immediately and made safe! Problems must be solved promptly.
Minor emissions will occur during normal seal operation. Depending
on the duty, this emission can appear as a gas, a liquid or a solid. For
emissions that are hazardous or toxic and a safe collection system is
required.
Hot surfaces have to be protected against accidental contact.
In order to avoid unforeseen hazards do not make unauthorised changes
to the sealed fluid, the specific duty or the seal parts.
Some mechanical seals are used in conjunction with an ancillary support
system; this is clarified either by the flush plan description on the seal
arrangement drawing or by contacting John Crane (also see Section 10).
It is important for the safe function of the seal that the support system
is assembled and incorporated into the machine before operation. This
manual should be read in conjunction with the appropriate documentation
for auxiliary systems and rotating machinery.
Alarm systems are often included in the ancillary support
system and the operator must ensure appropriate action
is taken promptly in the event of an alarm.
Maintenance with steel tools must be avoided in the presence of
substances classed as explosive group IIc according to
EN 60079-0:2012+A11:2013.
If the machine is being used in a EN 60079-0:2012+A11:2013 Zone 21 or
22, regular cleaning of dust from exterior surfaces is required.
4. Declaration of Incorporation (2006/42/EC)
For each standard product supplied into the EU a Technical File is
required and a Technical Record Sheet, satisfying the needs of 2006/42/
EC. When requested, a Declaration of Incorporation (for which a Technical
File exists) will be raised and signed by a John Crane appointed
representative.
5. Transportation and Storage
Transport and store the seal in its original packaging. To ensure
seals remain in good condition they should be stored in the following
environment:
1. Dry and dust-free
2. Ventilated at room temperature
3. Protected from direct effects of heat and ultraviolet light
4. All the elastomers used in the mechanical seal have a minimum shelf
life of 5 years except for butyl rubber which has a minimum shelf life
of 2 years. We recommend that the elastomers be replaced at these
intervals. It is also recommended that the elastomer replacement be
carried out by John Crane personnel.
If used seal parts are to be shipped they must be
cleaned and decontaminated before shipping. It is the
responsibility of the machine user to ensure that any
parts being shipped have appropriate safe-handling
instructions externally attached to the package. Without
this information there will be a refusal to handle the
goods. If required a decontamination/transportation
certificate is available from John Crane. Refer to
document EDS1001.
For additional information on transportation and storage, contact your
local John Crane facility and request a copy of of document I-Storage.
If any machine with an installed component seal has been stored with
preservatives, before putting it back into operation the seal must be
removed, cleaned and dried. Particular attention must be applied to the
cleanliness of the faces and condition of the elastomers. For an installed
cartridge seal we recommend returning the complete cartridge to John
Crane for cleaning.
ATTENTION Ensure preservatives and cleaning agents do not affect
the elastomers.
ATTENTION Once the seal is fitted on the machine and the position
is set using setting devices do not re-engage them for
transportation and storage.
6. Seal Installation
Refer to the appropriate seal family installation instructions. Do not
excessively compress the seal before or during installation.
7. Before Starting the Equipment
1. Check the machine at the coupling for proper alignment of the driver
or motor.
2. Ensure that the gland plate nuts/bolts are securely tightened
according to the pump manual instructions, and all screws are
securely fastened.
3. Assemble the machine, ensure any setting spacers are removed from
the seal and turn the shaft (by hand if possible) to ensure free rotation.
4. Consult all available equipment operating instructions to check for
correctness of all piping and connections, particularly regarding seal
recirculation/flush, heating or cooling requirements, and services
external to the seal. See Section 10. Ensure all unused ports are
correctly plugged.
ATTENTION This mechanical seal is designed to operate in a liquid,
so the heat energy it creates is adequately removed.
The following check should be carried out not only after
seal installation, but also after any period of equipment
inactivity.
5. Check that the seal chamber fluid lines are open and free of any
obstruction, and ensure that the seal chamber is properly vented and
filled with liquid — refer to the pump instruction manual.
ATTENTION Except for dry running or gas lubricated seals which are
designed to operate without liquid, wet seals that are
operated without adequate liquid lubrication will often
give rise to a squealing noise from the seal area and
result in overheating and scoring or other damage to
the sealing surfaces, causing excessive emissions and a
reduced seal life.

TYPE
Before start-up, ensure that all personnel and assembly
equipment have been moved to a safe distance so there
is no contact with rotating parts on the pump, seal,
coupling or motor.
Seal installation should be handled only by qualified
personnel. If questions arise, contact the local John
Crane representative. Improper use and/or installation
of this product could result in injury to the person and/
or harmful emissions to the environment, and may
affect any warranty on the product. Please contact
the company for information as to exclusive product
warranty and limitations of liability.
8. Maintenance
During operation, periodic visual external inspection of the seal should
be carried out. A measure of seal condition is the level of emission of the
process or barrier fluid and as no maintenance is possible while installed,
the seal should be replaced when emissions become unacceptable. It is
recommended that a spare seal be held in inventory to allow immediate
replacement of a removed seal.
ATTENTION Machine adjustments that involve axial movement of the
shaft may cause damage to the seal while installed.
Before attempting impeller clearance adjustment with a cartridge seal,
refit the spacers then loosen all the drive collar socket set screws. With
the shaft in its new working position, tighten with new socket set screws
and remove the spacers. Keep the spacers for future use.
For a component seal (non-cartridge), remove the seal, adjust the
impeller clearance then re-fit the seal at its correct working length.
8.1 Decommissioning the equipment
Ensure that the machine is made safe to work on by using a secured
isolation under the sole control of the person(s) working on the machine
and which includes the following:
• The driver is fully isolated from the machine using an appropriate,
secured isolation method;
• Any pressure is safely and fully released;
• Any liquid is safely drained;
• Any gas safely vented;
• Any chemicals are safely and fully removed;
• Any other energy storage is safely and fully released;
• The isolation is proved to be effective at the point of work before work
is commenced.
If the machine has been used on toxic or hazardous
fluids, ensure that the machine is correctly
decontaminated and made safe prior to commencing
work. Remember that fluid is often trapped during
draining and may be present inside the seal chamber.
The machine instruction manual should be consulted to
check for any special precautions.
8.2 Removing the seal
NOTE Remove from the machine with care, the seal may be suitable
for reconditioning after service, if otherwise undamaged.
1. Referring to the machine instruction manual, dismantle the machine
sufficiently to expose the seal and the seal housing.
ATTENTION For a cartridge seal, the setting spacers must be refitted
before starting the removal procedure.
2. Deburr, clean and lubricate the shaft over which the seal will pass and
remove the seal unit in the reverse order to installation.
A mechanical seal must always be serviced after removal from the
machine. In order to maximise reliability and minimise safety risks, it
is strongly recommended that used seals are returned to John Crane
for rebuilding to as-new specification (essential for non-contacting gas
seals). Alternatively ask for John Crane service personnel to visit site. For
seal dismantling and assembly instructions, refer to John Crane.
See “Transportation and Storage” section regarding shipping.
NOTE It is recommended that a low pressure integrity test is carried
out after repair and before installation on the machine.
8.3 Spare parts
Only John Crane spare parts should be used to recondition seals.
It is advisable to stock on site sufficient spare seal cartridges or the
replacement parts shown on the installation drawing or as advised by
John Crane to allow immediate replacement of the seal in the machine.
The order codes for spare parts can be found in the parts list on the
installation drawing or from John Crane directly. In the case of non-
contacting gas seals, only complete cartridges should be stored.
The following data is necessary for spare part orders:
• Part number
• Quantity
9. Quality Assurance
This seal has been assembled in accordance with John Crane Quality
Assurance Standards and with proper machine maintenance and use
will give safe and reliable operation to the maximum recommended
performance as shown in any relevant approved John Crane publication.
10. Mechanical Seal Piping Plans
To create the optimum environment for the mechanical seal it is usually
necessary to add piping and sometimes extra equipment.
For advice on a specific application please contact John Crane.
For liquid lubricated seals, venting of air trapped around the seal faces
is essential for correct seal operation. For horizontal machines the best
method of automatically achieving this is a piping connection at top dead
center (TDC). For vertical machines a piping connection above the seal
faces is required.

Before installing the mechanical seal read the instructions carefully. Keep
for future use. Seal installation must only be carried out by a suitably
qualified person.
1. Check that the machine is clean and meets the fitting tolerances shown
in the figure above. (Misalignment can lead to excessive friction on the
PTFE centering device on 4610, 4620, EZ-1 and 4615 range).
2. Unpack cartridge, inspect for damage, wipe clean.
3. Lubricate the machine shaft or sleeve with a recommended lubricant.
See Recommended Properties of Barrier Liquids for Dual Seals, page 9.
4. Slide the cartridge on to the machine shaft or sleeve and rotate until the
barrier inlet port ports are in a suitable position for flush piping.
5. Ensure that gland plate sealing ring is in position then slide the cartridge
against the seal chamber.
6. Fit the gland plate fasteners and evenly tighten to the torque
recommended by the machine manufacturer.
7. Ensure the machine shaft is locked axially in its final correct position and
evenly tighten the cartridge drive collar socket set screws. See Table 1 or
Table 2 depending on cartridge type for torque values.
8. Remove any setting clips or spacers and store for future use in cartridge
removal. For EZ-1, 4610, 4615 and most 4620P seals there are no setting
clips to remove.
9. Turn the machine shaft by hand if possible to ensure free rotation with no
shaft binding.
10. Complete the required piping to the seal. See pages 6 and 7. Take care
not to use excessive thread sealant when making circulation pipe work
connections. Unused tapped connections must be safely plugged before
seal operation.
11. Ensure machine seal chamber and seal are safely vented before starting
the machine. This should be achieved through self-venting pipework.
When manual vents are necessary they must be installed and used
safely.
12. For liquid lubricated dual seals ensure that the seal lubrication system
is correctly filled with suitable liquid. See Recommended Properties of
Barrier Liquids for Dual Seals on page 9 for guidance on liquid selection.
13. For a dual pressurized arrangement ensure that the seal is pressurized to
a minimum of 1bar above the maximum machine seal chamber pressure
before the machine is pressurized. The seal pressure must be within the
seal and seal lubrication system operating pressure.
Once fitted, no adjustment is possible during the life of the mechanical
seal. When the mechanical seal requires replacement, John Crane can
supply a new or reconditioned seal to the original specification.

Series Gland Installation Guide
Piping connections
A cast gland plate is normally used up to shaft sizes 3.000 inch/75 mm.
A letter identifying the function may be marked on the blank pads as
follows:
All standard pipework connections are tapped 3/8 inch NPT.
Special 5610 and 5615 seals may use a dual seal gland plate with a single
seal, for conical seal chambers. All ports are plugged. Use no flush. A
quench bush allows a quench by piping ports 1 and 3 as shown for “Single
Seal with Quench”.
Seal sizes above 75 mm/3.000 inch use a fully machined gland plate
with radial drillings that allow bi-directional shaft rotation. Pipework
connections are tapped 1/2 inch NPT.
ATTENTION Some gland plates will have unused connections sealed
with metal plugs.
As supplied, these gland plates have metal plugs fitted as follows:
Inch sizes – see relevant clockwise ANSI pump illustrations
mm sizes – see relevant clockwise DIN pump illustrations
Remaining connections are fitted with temporary plastic blanking
plugs that cannot hold pressure. All plugs should be left in place until
connection of the pipework. Plastic plugs must be replaced with metal
plugs or appropriate fittings.
NOTE Ensure the seal is correctly piped and plugged as shown in the
relevant illustration for the particular application. Due to the
wide variety of design of pumps and other machines the piping
illustrations may not be valid in all cases. Consult John Crane
if an alternative piping arrangement is required.

Notes
• Direction of rotation is as viewed from the driver.
• For single seal counter-clockwise applications a gland plate is required
with port 4 drilled. If this port is not drilled contact your local John
Crane Service Center.
• A Plan 11/Plan 13 flush for horizontal/vertical shafts is always
recommended for single and dual seals.
• Before starting the pump after seal fitting vent the seal chamber
through the pump’s lantern ring connection at TDC if safe to do so.
• If manual venting of the seal is required, a safe method must be used. A
self-venting installation is always the preferred option.
• For seals over 75 mm/3.000 inch the connection positions may vary for
other bolting arrangements.
• For seals other than the 5600 series follow the installation guide
For Gland Piping Seals Other Than 5600 Series.

Plan 52/53A – piping layout
For Gland Piping Seals Other Than 5600 Series
NOTE Thorough venting of the seal faces is essential for long seal life.
• For single seals on a horizontal shaft the flush should be at TDC to
give a self-venting seal chamber. If this is not practical then either
manually vent the seal chamber using the pump’s lantern connection
at TDC if it is safe to do so or drill a 5 mm/3/16 inch hole in the pump
throat bush at TDC.
• For single seals on a vertical shaft the flush should be above the seal
faces to ensure self-venting.
• For dual seals on a horizontal shaft the barrier outlet should be at TDC
to ensure self venting of the seal. If this is not practical then manually
vent the seal if it is safe to do so. The seal chamber should be vented
as described in paragraph 1.

• For dual seals on a vertical shaft the barrier outlet should be above the
upper seal faces to ensure self-venting. The flush connection should be
above the level of the lower faces.
• For a thermosiphon system, follow the piping layout on page 8. A
pumping ring is always recommended for use with a thermosiphon
system.
Notes
• In a dual unpressurized arrangement the inboard seal is cooled and
lubricated by the pumped liquid at seal chamber pressure. The outboard
seal is lubricated by the barrier liquid typically at atmospheric or flare
pressure.
• In a dual pressurized arrangement both seals are cooled and lubricated
by the barrier liquid maintained at a pressure higher than the seal
chamber pressure. This arrangement isolates the pumped liquid from
the atmosphere.
Alternative Terms for Gland Plate Ports

Recommended Properties of Barrier Liquids for Dual Seals
• A good lubricant with good heat transfer properties
• Clean
• Compatible with the process fluid and seal materials of construction
• Stable over the seal’s operating range
• Non-hazardous
• A viscosity < 15 cSt/80 SSU @ 40°C/104°F and ideally between
1 and 10 cSt/31 to 60 SSU @ 65°C/150°F
• A maximum viscosity of 680 SSU/150 cSt at the minimum ambient
temperature
