General Installation and Maintenance Instructions for Machinery Components

4. Transport, Storage

The mechanical seal and related equipment must be transported and stored in the unopened,

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 subjected

to heavy impacts during transport must not be installed.

An inspection by Flowserve or its appointed representative is strongly advised.

After a storage period of 3 years the mechanical seal must be inspected for its “as new”

properties. This applies in particular to the seal faces and secondary sealing elements.

An inspection by Flowserve becomes necessary.

If the equipment is to be preserved with the mechanical seal(s) installed, the preserving

medium must not impair the function of the mechanical seal by e.g. fouling of the seal

faces and/or attack the secondary seals.

The mechanical seal can in principle be transported with suitable means like lifting

accessories.

5. Equipment Check

5.1 Follow plant safety regulations prior to equipment disassembly:

5.1.1 Wear designated personal safety equipment

5.1.2 Isolate equipment and relieve any pressure in the system

5.1.3 Lock out equipment driver and valves

5.1.4 Consult plant Material Safety Data Sheet (MSDS) files for hazardous material

regulations

5.2 Disassemble equipment in accordance with the equipment manufacturer’s instructions

to allow access to seal installation area.

5.3 Remove existing sealing arrangement (mechanical seal or otherwise).

Clean seal chamber and shaft thoroughly.

5.4 Verify the shaft dimensions as shown on the seal assembly drawing. In spect surfaces

under gaskets to ensure they are free from pits or scratches. Break all sharp corners

on shaft steps, threads, reliefs, shoulders, key ways, etc. over which gasket(s) must

pass and/or seal against.

5.5 Verify the seal chamber bore or OD pilot fit as shown on the seal assem bly drawing.

5.6 Check seal assembly drawings for any modifications (reworks) to be made to the

equipment for mechanical seal installation and act accordingly.
