Shutdown / Storage / Preservation; Storage Of New Pumps; Measures To Be Taken For Prolonged Shutdown; Returning To Service After Storage - KSB RDLO Series Operating Instructions Manual

Close the auxiliary connections. The shaft seal in
pumps where the liquid is fed in under vacuum
must also be lubricated with sealing liquid during
standstill.
In the event of frost risk and/or prolonged
shutdowns, the pump – and if applicable the cooling
chambers - must be drained or otherwise protected
against freezing.

Shutdown / Storage / Preservation

Each KSB pump leaves the factory carefully
assembled. If commissioning is to take place some
time after delivery, we recommend that the following
measures be taken for pump storage.
6.5.1

Storage of New Pumps

- New pumps are supplied by our factory duly
prepared for storage. Maximum protection for up
to 12 months, if the pump is properly stored
indoors.
- Store the pump in a dry and vibration-free
location location.
Rotate the pump shaft by hand once a month to
-
prevent the rolling element bearings from being
damaged.
Should there be a risk of humidity condensation
inside the pump, replace the lubricant fill of the
bearings and check the condition of the rolling
element bearings prior to commissioning.
6.5.2 Measures to Be Taken for Prolonged
Shutdown
1. The pump remains installed; periodic
check of operation
In order to make sure that the pump is always ready
for instant start-up and to prevent the formation of
deposits within the pump and the pump intake area,
start up the pump set once a month or once every 3
months for a short time (approx. 5 minutes) during
prolonged shutdown periods. Prior to an operation
check run ensure that there is sufficient liquid
available for operating the pump.
2. The pump is removed from the pipe and
stored
Before putting the pump into storage carry out all
checks specified in sections 7.1 to 7.4. Then apply
appropriate preservatives.
Spray-coat the inside wall of the pump casing, and
in particular the impeller clearance areas, with a
preservative. Spray the preservative through the
suction and discharge nozzles. It is advisable to
close the nozzles (for example with plastic caps).
6.6

Returning to Service after Storage

Before returning the pump to service carry out all
checks and servicing work specified in sections 7.1
and 7.2.
In addition, the instructions laid down in
sections 6.1 "Commissioning" and 6.4.3 "Pump
Operating Range" must be observed.
Upon completion of the work, all safety-
related and protective equipment must be properly
refitted and/or reactivated before starting the pump
set.

A regular servicing schedule will help avoid
expensive repairs and contribute to trouble-free,
reliable operation of the pump with a minimum of
servicing expenditure and work.
Work on the unit may only be carried out
with the electrical connections disconnected.
Make sure that the pump set cannot be
