intervals so that they cannot exceed a thickness of 5 mm on the
surfaces of the faces.
It must be ensured, e.g. in the form of a level monitor, that the
sealing chamber is completely vented and filled with fluid in all
running states if it is to minimise the heat generated by friction
and therefore the surface temperature of the seal elements.
If the application limits for running in accordance with these
instructions cannot be observed, the temperature of the supply
liquid and / or the installed components must be monitored at
all times by a device that shuts down the machine once a criti-
cal temperature is reached. This device can consist of resistance
thermometers or thermoelements.
The seal chamber must be vented carefully before startup
8.3 Observe the start-up. If the seal runs hot or squeals, check the
seal flush system. Do not allow the pump to run for any extended
time if the seal gets hot or squeals.
8. Do not exceed corrosion limits. The ISC2 seal is designed to resist
corrosion through proper material selection. Do not expose the ISC2
seal materials of construction to products outside of their corrosion
limits. Consult Flowserve for chemical resistance recommendations.
8.5 Do not exceed pressure and speed limits established for the
ISC2 seal.
8.6 Do not exceed the temperature limits of the ISC2 seal based on
the materials of construction. For dual seals using supply tanks
with cooling coils, turn on cooling water to the supply tank before
start-up.
