Before the pump is started, make sure that:
Only liquids with conductivity >1000
[pS/m] (Refer to PD CLC/TR 60079
–32–
1:2015) are used.
The maximum liquid temperature (t
max
)
stated on the pump nameplate must
never be exceeded.
The combination of the pump and the
dry-running protection is described in the
Explosion

bearings is recommended. The bearings must be
replaced after 25000 operating hours or according to
the
motor
supplier
maintenance
instructions,
whichever is shorter.
Motor with regreasable bearings
Follow motor supplier maintenance instructions.
