• Balanced.
• System attached to the shaft by allen
screws.
• Not dependent on the rotation direction.
(*) 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:
The springs are not in contact with the fluid. Ideal for
working with particle-laden fluids in which standard
designs tend to become blocked.
Internally balanced, with no need for a stepped shaft
Suitable for working in applications with high pres -
sures. The O-ring resting on the shaft does not cau -
se wear as there is no axial movement (changes in
pressure).
