5 Operational Recommendations
5.1 Do not exceed corrosion limits. The ISC is designed to resist
corrosion by most chemicals. However, do not expose the ISC
materials of construction to products outside of their corrosion limits.
The ISC assembly drawing lists the materials of construction.
Consult Flowserve for chemical resistance recommendations.
5.2 Do not exceed the recommended maximum pressure and
speed limits shown in the ISC brochure.
5.3 Do not exceed the temperature limits of the ISC. The materials of
construction are listed on the ISC assembly drawing. For dual seals
using supply tanks with cooling coils, turn on cooling water to the
supply tank before start-up.
5.4 Do not start up or run the ISC dry. Buffer/barrier fluid must be in
the seal cavity for dual seals at all times during pump operation.
Process fluid must be in the pump volute at all times during single
seal operation.
