7. Servicing, Maintenance
7.1 General remarks
Work should only be carried out on the pump or
pump unit when it is not in operation. You must
observe chapter 2.
Maintenance and servicing work must only be
carried out by trained, experienced staff who
are familiar with the contents of these Operat-
ing Instructions, or by the Manufacturer's own
service staff.
7.2 Mechanical seals
Before opening the pump, it is essential that
you note chapter 2 and chapter 8.
If the liquid being handled leaks out at the mechanical
seal, it is damaged and must be replaced.
Replacement of the mech. seal according to accom-
panying "Mounting Instructions for Shaft sealing".
7.3 Stuffing boxes
Stuffing boxes require constant maintenance, see
chapter 6.2 section "Stuffing box". If the leakage rate
can no longer be set correctly, the packing is worn out
and must be replaced in good time (increased wear
on shaft sleeve). Replacement of stuffing boxes acc.
to attached "Mounting Instructions for Shaft Sealing".
Because of the risk of accidents, addition of
packing to pumps during operation or at operat-
ing pressure or temperature is strictly forbidden!
