• Balanced.
• Multispring.
• Not dependent on the rotation direction.
• Barrier fluid connections.
(*) 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.
DESCRIPTION:
A double cartridge with a "face to face" arrangement
which permits operation with barrier fluid in excessive
pressure with respect to the working fluid (P1+1.5-2
Kgr/cm2)
The sleeve includes a pumping ring that facilite the
barrier fluid movement. The connections of Liquid
barreir IN and OUT have to be connected according
the rotation direction.
CONNECTIONS (R):
From 25 mm to 35 mm: 1/4” NPT.
