iSave 21

5.3 Materials

All critical parts of the iSave are made of super-duplex 1.4410/UN S32750 or the like.
Non-critical parts that are not in contact with sea water are made of AISI316.
The shaft to the electrical motor is sealed by a standardised mechanical seal.
For a detailed material/part overview see appendix

5.4 Temperature and corrosion

The chart below illustrates the corrosive resistance of different types of stainless steel re-
lated to NaCl concentration and temperature.
Depending on the NaCl concentration, the fluid temperature must be between: +2°C to
+50°C (+35.6°F to 122°F).
In order to minimise the risk of crevice corrosion, always flush the iSave according to the
specified start/stop procedure.

5.5 Dimensions and weights

For dimensions and weights please refer to the iSave datasheet. See appendix 10.3.

5.6 Electrical motor data

See datasheet in appendix 10.3 and "Operating and Maintenance instructions, electric mo-
tor" in appendix 10.8.
