CHARACTERISTICS:
• Balanced.
• Wave spring.
• Not dependent on the rotation direction.
• Barrier fluid, purge and drain connections.
DESCRIPTION:
Double cartridge seal with a “tandem” arrangement
suitable for working with pressurised or non-pressu-
rised barrier fluids. Recommended in applications in
which a high level of safety is required.
Possibility of incorporating a pumping ring to reduce
the temperature gradient between the mechanical seal
contact surfaces.
CONNECTIONS (R):
From 25 mm to 60 mm: 1/4” NPT.
From 63 mm to 110 mm: 3/8” NPT.
(*) The temperature resistance depends on the material
of the secondary seals used.
The operating limits are defined by the PV factor which
is determined for the sealing system characteristics and
those of the application.
