General Installation and Maintenance Instructions for Machinery Components

ESA position statement: http://www.europeansealing.com/statements.html

For applications which require information on expected surface temperatures of

the mechanical seal faces, Flowserve document “ATEX 137 information declaration”

is available upon request. This document allows users to determine typical surface

temperatures based upon seal design, operating conditions and face materials and

may be used by the users to comply with ATEX 1999/92/EC (ATEX 137).

1.4 Functional requirements

The proper functioning of a mechanical seal is only achieved once the following

conditions have been met:

• Thesealingsurfacesarelappedwithinspecification.

• Perpendicularityandconcentricitybetweentheshaftandthesealchamberface

and bore respectively

• Freedomofmovementofthespringloadedcomponentsinaxialdirection

• AxialandradialshaftmovementswithinFlowserveorOEMtoleranceswhichever

is the tightest.

• Thesealisusedundertheconditionsforwhichitwasselected.

• Theequipmentinwhichtheseal(s)is(are)installedisoperatedwithinnormal 

parameters (no cavitation, excess vibration etc.)

• Preventionofsedimentationonshaftorsleevesurfacescausedbyforinstance 

crystallisation or polymerisation

• Permanentliquidorgasfilmbetweenthesealingsurfaces,dependingonsealtype.

Failure to meet these requirements will result in excessive leakage and / or shortened seal life

and may result in high component and surface temperatures (see the directive 94/9/EC,

1999/92/EC and EN 13463-5).

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 instruc-

tions will contribute to long and trouble free running of the mechanical seal. For related mecha-

nical seal auxiliary equipment (reservoirs, coolers, etc.), separate instructions will be provided.
