2.1 Intended use
Single mechanical seals for plastic-lined pumps of the
series SCK are suitable for the use of aggressive and
pure media.
The instructions contained in the operating
manual or contractual documentation are to be
observed, if necessary consult the manufacturer.
All the important features are documented in the data
sheet included in the scope of delivery.
3 Product description
For a product description of the pump, see the
installation and operating manual for the SCK series.
The sectional drawing shows a stationary single
mechanical seal RG-4. See Section 7.1. All components which come into contact with the
process medium are either lined with plastic or are
made of other resistant materials, e.g. silicon
carbide.
4 Commissioning / Shutdown
4.1 Initial commissioning
See installation and operating manual for the series
SCK.
4.2 Mechanical seals
The design and material combination are specified in
the data sheet.
The proper condition of the components and
the protective facilities must be ensured to
prevent any risk from escaping medium.
The regulations and recommendations of
the mechanical seal manufacturer must
always be observed.
4.2.1 Use in an explosive area
Use in an explosive area means that ATEX-
compliant mechanical seals must also be
used.
In particular, it is imperative to observe the ATEX
notes in the operating manual of the mechanical seal
manufacturer.
For example, the maximum temperatures of the
medium must be observed, a lack of lubrication of the
mechanical seals avoided etc.
4.2.2 Stationary, single mechanical seal
RG-4
Pumps fitted with a single mechanical seal must
not be started up before they are filled with
medium.
Otherwise the single mechanical seal is not lubricated
and cooled and could be damaged.
See sectional drawing in Section 7.1.
4.3 Improper operation and their
consequences (examples)
Inadmissible modes of operation, even for a
short time, can result in serious damage to the
unit.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and
induced charges, mechanical and electric sparks) may
result from these inadmissible modes of operation;
their occurrence can only be prevented by adhering to
the intended use.
For examples, see installation and operating manual
SCK, Section 6.6.
