Fluiten cartridge seals are
designed with flexibility in
mind, to suit a large number
of applications.
This optimisation, reduces
the need to carry extensive
spare parts , normally
associated with multiple
variations in seal usage.
The choice of materials, and
the careful attention to detail
for every solution, are the
reason behind the great
success of the Fluiten ‘ C’
type cartridge range. This
range is now being use with
confidence, and complete
satisfaction, by major
manufacturers of pumps and
mixers.
This catalog shows the
second generation of this
range of cartridges with the
last improvements according
to the current security
requirements of european
community

The Cartridges FLUITEN seals range are certified according the ATEX directive 94/9/CE
(TÜV) which has defined the European requirements for equipment installed in critical
potential explosive areas.
A declaration of conformity and a specific instruction manual can be supplied on demand.
This documentation complete the equipment certification required for the duty validation.
For high risk applications Fluiten can provide double mechanical seals lubricated and
monitored by a thermocouple which has the probe located inside the stationary rings or
in contact with the barrier fluid to have direct temperature relief.
