ISC Innovative Standard Cartridge Seal - Installation Instructions for Machinery Components
Plant regulations concerning work safety, accident prevention and pollution must be strictly
adhered to.
This mechanical seal has been designed and built to seal rotating equipment. Damages
resulting from use in other applications are the responsibility of the user.
Failure, recovery or fluctuation in power supply to the machine and/or supply sys-
tem may not expose persons or environment to dangerous situations or harm the
functionality of the mechanical seal.
Guards that are provided by the equipment manufacturer have to be in accordance
with plant regulations, but should not create additional danger. These guards
have to ensure proper access to the working area required for maintenance to the
mechanical seal.
The electricity supply of the equipment must be in accordance with directive
006/95/EC. When machinery is powered by a source of energy other than electri-
city this may not cause dangerous situations for persons and environment.
3. General
All illustrations and details in these installation instructions are subject to changes that
are necessary to improve product performance without prior notice.
The copyright of these instructions is the property of Flowserve. These instructions are
intended for Maintenance, Operating and Supervisory personnel and contain regulations
and drawings of a technical character that may not, in full or in part, be copied, distribut-
ed, used without authorisation for competitive purposes, or given to others.
It should be understood that Flowserve does not accept any liability for instances of
damage and/or malfunctioning incurred through non-adherence to these installati-
on instructions.
4. Transport, Storage
The mechanical seal and related equipment maust be transported and stored in the uno-
pened, original shipping box. The warehouse in which the mechanical seals and related
equipment are stored must be dry and free of dust. Avoid exposing equipment to large
temperature fluctuations and radiation.
Parts or complete mechanical seals that have been dropped or otherwise have been sub-
jected to heavy impacts during transport must not be installed.
An inspection by Flowserve or its appointed representative is strongly advised.
• The seal is run under the conditions for which it was selected
• The equipment in which the seal(s) is (are) installed is run within normal parame-
ters (no cavitation, excess vibration etc.)
• Prevention of sedimentation on shaft or sleeve surfaces caused by for instance
crystallisation or polymerisation
• Permanent seal liquid film between the sealing surfaces
If these function conditions are not fulfilled, the consumption of product, for exa-
mple, is increased and parts of the product can escape into the atmosphere. Other
effects can include high component temperatures.
See the directive 94/9/EC, 1999/9/EC and EN 146-5.
Failure to meet these requirements will result in excessive leakage and/or shortened
seal life.
2. Safety
DANGER: This means that personal danger or major material damage can occur
when no attention is paid to this.
ATTENTION: This means that important information is pointed out that may also be
overlooked by skilled personnel. The information can be important to
avoid personal injury or material damage.
Please read these instructions carefully. Installation in accordance with the following
instructions will contribute to long and trouble free running of the mechanical seal.
For related mechanical seal auxiliary equipment (reservoirs, coolers, etc.), separate ins-
tructions will be provided.
The ultimate user must ensure that personnel assigned to handle, install and run the
mechanical seal and related equipment is well acquainted with the design and operating
requirements of such equipment.
For this personnel it may be required to wear protective clothing as per the plant’s
safety regulations.
Damage to any of the seal components and in particular the faces may cause (ex-
cessive) leakage in liquid or gas form. The degree of hazard depends on the sealed
product and may have an effect on people and/or the environment. Components
coming into contact with leakage must be corrosion resistant or suitably protected.
EXPLOSION PROTECTION – This means that failure to observe these instructions
will involve the risk of explosion in potentially explosive environments which can
cause harm to persons and / or considerable damage to property.
