5 Installation/Dismantling
NOTE
Priority shall be given to the installation instructions and/or installation sequence in
the documents of the pump set into which this mechanical seal is to be installed.
This also applies to the dismantling instructions and/or dismantling sequence.
5.1 Permissible aids
CAUTION
Impermissible cleaning agents
Damage to the seal faces at the mechanical seal!
▷ For removing minor contamination use only paper tissues and ethyl alcohol.
▷ Do not use dirty cleaning cloths or cleaning cloths that leave behind lint.
CAUTION
Impermissible assembly aids
Sealing elements made of ethylene propylene diene rubber perishing or swelling
up!
▷ Never let sealing elements come into contact with mineral oil base lubricants.
▷
Use permissible lubricants only.
▷ Verify that the assembly aids are silicon-free.
▪ Lubricants
2)
– Permanent lubricants, such as non-mineral grease (Klüber Asonic HQ 72-102)
are used for elastomers that do not serve to transmit the torque. Examples
are mating rings with an anti-twist lock or primary rings that move axially
relative to the pump components.
– Non-permanent lubricants such as a soap solution, for example, are used for
elastomers that serve as a sealing element and, in addition, transmit the
torque. An example would be a mating ring without anti-twist lock.
▪
Recommended cleaning agent for seal faces and grub screws: ethyl alcohol
▪ Thread-locking agent: Loctite, No. 243
▪ Open-ended wrench, ring spanner, socket wrench (cleaned, no impact tools)
▪ Torque wrench (cleaned)
5.2 Prerequisites
▪ Chamfered ends to EN 12756.
▪ Installation dimensions to DIN EN 12756
▪ Surface roughness of pump components to DIN EN 12756
▪
Shaft run-out to ISO 5199:
– Shaft diameter ≤ 50 mm: 0.05 mm max.
– Shaft diameter 50 to 100 mm: 0.08 mm max.
– Shaft diameter > 100 mm: 0.10 mm max.
▪ Face run-out of the shaft in relation to the vertical connection surface of the
casing:
– Shaft speed ≤ 750 rpm: 0.2 mm max.
2 Lubricants must be compatible with all fluids used. They must not be aggressive to the secondary sealing
elements.
