In order to minimise the risk of crevice
corrosion, always flush the MPE 70
according to the specified start/stop
procedure.
5.3 Materials
All critical parts of the MPE 70 are made of
super-duplex 1.4410/UN S32750/1.4462/
UN S32205/S31803 or the like.
Non-critical parts that are not in contact
with sea water are made of AISI 316.
The shaft to the electrical motor is sealed by
a standardised mechanical seal.
5.4 Temperature and corrosion
The chart below illustrates the corrosive
resistance of different types of stainless steel
related 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).
5.5 Dimensions and weights
For dimensions and weights please refer to
the MPE 70 data sheet. See appendix 11.1.
