See section 3.2 Handling and lifting the
The pump has not been treated for storage from
factory.
Prepare the pump for storage as described
below to avoid material damage.

6.1 Preparation for storage

Prepare the pump properly for storage both inside
and outside.
Use RUST-BAN 335, for example, as corrosion
inhibitor.
Applying corrosion inhibitor to the inside of the
pump
1. Close the inlet-side flange with a blind flange.
2. Fill the pump with corrosion inhibitor.
3. Turn the shaft slowly by hand against the pump's
direction of rotation.
4. Continue filling and turning until corrosion
inhibitor comes out of the outlet-side flange
without bubbles.
5. Close the outlet-side flange with a blind flange.
Applying corrosion inhibitor to the outside of the
pump
Apply corrosion inhibitor to all bare metal parts using
a brush or spray can.

6.2 Storage

1. Seal all openings with blind flanges, blind plugs
or plastic covers.
2. Make sure the storage room meets the following
conditions:
– dry
– frost-free
– vibration-free
– dust-free.
3. Turn the shaft once a month and make sure the
shaft and bearing change position in the process.

6.3 Removing corrosion inhibitor

Only necessary for pumps treated with corrosion
product.
inhibitor.
1. Choose among the following cleaning agents:
– benzene
– wax solvents
– diesel
– paraffin
– alkaline cleaner.
2. Remove the corrosion inhibitor from all bare
internal parts of the pump.
3. Dispose of cleaning agents in accordance with
local environmental rules and requirements.
4. For storage times exceeding six months:
– Replace the elastomer parts made of EPDM.
– Check all elastomer parts (O-rings, shaft seals)
for proper elasticity and replace them, if
necessary.
High water pressure or spray water can
damage bearings.
Do not clean bearing areas with a water or
steam jet.
Using wrong cleaning agent may cause
damage to seals.
Make sure the cleaning agent does not
corrode the seals.
