6.10 Remove the setting devices from the drive collar by loosening
the cap screws. See Figure 5. Save the setting devices and fas-
teners for future use when the pump impeller is reset or when the
seal is removed for repairs.
Vibrations must be prevented from transferring to the installed
ISC2 during operation, e.g. through structural measures imple-
mented on the machine.
The machine to take the ISC2 must be earthed in accordance with
the applicable regulations for electrical installations (e.g. VDE
rules) to conduct away any electrostatic build-up and so prevent
spark formation.
6.11 Turn the shaft by hand to ensure unobstructed rotation.
6.12 See Functional Recommendations before start-up.
Conduct a static pressure test. Do not exceed the max. pressures.
7. Piping Recommendations
7.1 Install and maintain an adequate piping plan. Ensure that pip-
ing is connected to the correct pipe ports to prevent unsafe
situations. The connections on the mechanical seal are prop-
erly marked.
The ISC2 seal requires a clean, cool environment for maximum
seal life. Typical piping plans are listed below. Contact Flowserve
for additional piping plan information or technical support.
Plan 11: default inner seal flush from pump discharge on horizon-
tal pumps (single seals)
