GENERAL SAFETY NOTES
Any person involved in assembly, disassembly, start-up, operation and
maintenance of the mechanical seal must have read and understood this
operating manual and in particular the safety notes. We recommend the user
having this confirmed.
EagleBurgmann mechanical seals are manufactured to a high quality level and they
have a high working reliability. Yet, if they are not operated within their intended
purpose or handled inexpertly they may create risks.
The machine has to be set up in such a way that seal leakage can be led off and
disposed of properly and that any personal injury caused by spurting product in the
event of a seal failure is avoided.
Any operation mode that affects the operational safety of the mechanical seal is not
permitted.
Unauthorised modifications or alterations of the mechanical seal are not permitted.
Mechanical seals must be installed, operated, maintained and removed by
authorised, trained and supervised qualified personnel only. In case the
personnel has no long years of experience in handling with and operating of
mechanical seals and their supply systems, for this purpose, EagleBurgmann offers
corresponding seminars for achieving of the required knowledge.
The responsibilities for the respective jobs to be done have to be determined
clearly and observed in order to prevent ambiguous competencies from the point of
security.
Any work to be done on the mechanical seal is generally only permitted when the
seal is neither operating nor pressurised. The machine must be protected against
accidental start-up.
WARNING! Seals that have been used with hazardous substances must be properly
cleaned so that there is no possible danger to people or to the environment.
Apart from the notes given in this manual, the general regulations for worker's
protection and those for prevention of accidents have to be observed.

Rev. 2 05/02/2020
Instructions for worker's protection
WARNING! If the medium to be sealed and/or the supply liquid is subject to the
Hazardous Substances Regulation (GefStoffV), the instructions for handling
dangerous substances (safety data sheets to Directive 91/155/EEC) and the
accident prevention regulations have be observed.
Medium to be sealed and/or supply medium may escape if the seal fails. Injury of
persons and environment must be prevented by the user providing for splash
protection and wearing of safety goggles. Care has to be taken by the user for
proper disposal of the leakage. The user has to control these measures.
The user has to check what effects a failure of the mechanical seal might have and
what safety measures have to be taken to prevent personal injury or damage to the
environment.
Notes on explosion protection
Mechanical seals are mechanical parts, which are put in circulation for general
technical purposes. They are not components within the meaning of Directive
2014/34/EU.
The respective probation as to explosion protection for the provided temperature
class must be carried out during the conformity assessment of the machine, into
which the mechanical seal is installed, by the machine manufacturer.
In case the assessment is carried out by the end user, the respective additional
operating manual has to be requested from EagleBurgmann.

TRANSPORT / STORAGE
Transport
If not specified differently by contract, the EagleBurgmann standard packaging is
used which is suitable for dry transport by truck, train or plane. The warning signs
and notes on the packaging must be observed.
In addition, seaworthy packaging may become necessary.
Notes for income inspection:
Check packaging for visible damage.
Open packaging carefully. Do not damage or lose parts supplied separately.
Check if consignment is complete (delivery note). Inform the supplier immediately
in writing if parts are damaged or missing.
The mechanical seal has to be protected from damage during transport and storage.
The transport case in which the seal is supplied is well suited for this purpose and
should be kept for a possible return transport.
ATTENTION! If the machine as well as the mechanical seal installed into the machine
are transported together, the shaft must be protected from deflection at all times,
shocks and axial displacement by means of a suitable machine support.
Damage at the M.S. caused by insufficient protection during transport is excluded
from the warranty.

Storage, "mothballing" (long term storage)
The following recommendations apply to all mechanical seals which have been
supplied and stored in their undamaged original packaging, as well as to seals
which have been installed in a machine (e.g. pump, compressor, agitator, etc.) but
have not yet been put into operation.
Mechanical seals and spare parts are super finished and repeatedly tested machine
elements. For storage special conditions have to be followed.
Sliding materials and secondary sealing elements are subject to material-specific and
time-based alterations (distortion, ageing) which might reduce the full efficiency of the
mechanical seals. Hence, this may be avoided by observing the storage instructions.
For the stock keeping of elastomers, special conditions are required. For all rubber-
elastic parts the rules of DIN 7716 resp. of ISO 2230-1973 (E) are valid.
Optimum conditions for storing of mechanical seals
dust free
moderately ventilated
constant temperature
relative air humidity below 65 %,
temperature between 15 °C and 25 °C.
Protect the mechanical seal from
direct exposure to heat (sun, heating)
ultraviolet light (halogen or fluorescent lamps, sunlight, arc welding)
presence or development of ozone (arc welding, mercury vapour lamps, high-
voltage devices, electric motors)
risk of embrittlement of elastomeric materials
It must be recognised that a difference exists between:
M.S. stored in the stock room
M.S. installed in the machine, but not yet in operation.

Rev. 2 05/02/2020
M.S. in the stock
IMPORTANT! Store the seal in the original packaging lying on a flat surface.
Check the packaging periodically for damage.
Sealings packed in plastic-foil with humidity indicators have to be checked every
8 weeks. The check has to be recorded.
Packaging exceeding 50 % rel. humidity values must be sent to the manu-
facturer or the nearest EagleBurgmann service centre for inspection and new
packaging.
Unused stored mechanical seal under optimum conditions:
For reasons of safety, after 3 years from delivery of the mechanical seal the M.S.
should be returned to EagleBurgmann resp. nearest EagleBurgmann Service
centre for
Exchange of all secondary seals and springs
Verification of the flatness of the faces
Perhaps static pressure test.
M.S. installed into the machine:
ATTENTION! "Mothballing" (long term storage) of the mechanical seals is not allowed.
In case of a "mothballing" (long term storage) of complete machines with mechanical
seals installed EagleBurgmann has to be contacted.
Do not use corrosion protection agents.
Risk of deposition and possibly chemical attack of the secondary seals.
Due to longer erecting times of newly designed plant the period between delivery of
the mechanical seal and its installation and start-up in the machine may exceed a
period of 2-3 years.
After 3 years at the latest and in good time before the planned start-up of the plant
the seal has to be dismantled sent to the manufacturer or the nearest
EagleBurgmann service centre where it can be checked and reconditioned, if
necessary.
EagleBurgmann does not accept any warranty for damage caused by improper
storage.

Materials
The materials of the mechanical seal depend on the application and are bound to the
customer order. They can be found on the drawing, and/or in the parts lists attached
to the documentation.
Designated use
This mechanical seal is exclusively designed for the use in the specified application.
A different utilisation or usage of the seal going beyond the specification is
considered contrary to its designated use and excludes a liability for possible
consequences by the manufacturer.
Operation of the seal under conditions lying outside the limits stated in paragraph
"Operating limits" is considered contrary to its designated use.
Should the mechanical seal be operated under different conditions or in a different
application EagleBurgmann must confirm that such a change is safe in advance of
subsequent operation.
Changes to operating conditions have to be documented.
