3. Transportation and storage

The pump is supplied from the factory in proper packing in which
it should remain until it is to be installed.
Make sure that the pump cannot roll or fall over.
All lifting equipment must be rated for the purpose and checked
for damages before any attempts are made to lift the pump. The
lifting equipment rating must under no circumstances be
exceeded. The pump weight is stated on the pump nameplate.
Always lift the pump by its lifting bracket or by means
of a fork-lift truck, never by means of the motor cable
or the hose/pipe.
Note: Do not remove the protection from the free end of the sup-
ply cable until the electrical connections are to be made. The free
cable end must never be exposed to moisture or water, whether it
is protected or not. Non-compliance may involve the risk of dam-
age to the motor.
For long periods of storage, the pump must be protected against
moisture and heat.
Storage temperature: –30°C to +60°C.
After a long period of storage, the pump should be inspected
before it is put into operation. Make sure that the impeller can
rotate freely. Pay special attention to the condition of the shaft
seals and the cable entry.

4. Installation

During installation, always support the pump by
means of lifting chains or place it in horizontal
position to secure stability.
The loose nameplate supplied with the pump should be fixed at
the installation site.
All safety regulations must be observed at the installation site,
e.g. the use of blowers for fresh-air supply to the pit.
Do not put your hands or any tool into the pump suc-
tion or discharge port after the pump has been con-
nected to the electricity supply, unless the pump has
been switched off by removing the fuses or switching
off the mains switch. It must be ensured that the elec-
tricity supply cannot be accidentally switched on.
Prior to installation, check the oil level in the oil chamber, see
section 7.1 Oil check and oil change.
The S1 and SV pumps are designed for various installation ver-
sions.
The following types of submerged installation are possible:
Installation type Description
S Submerged installation on auto-coupling
Submerged installation on auto-coupling
C
Motor cooling is independent of liquid level
S Submerged installation, portable
Submerged installation, portable
C
Motor cooling is independent of liquid level
Two types of dry installation is possible:
Installation type Description
Vertical dry installation
D
Horizontal dry installation
Pumps for dry installation are installed permanently in a pump
room.
Figures 3 to 7 show the possible installation versions.
Pumps with "U" on the nameplate cover types S, C and D.
Installation types S & C (U):
Submerged installation on auto-coupling
Fig. 3
Permanent installation in pit. The pump can easily be pulled out
or lowered into the pit by means of the guide rails and the lifting
chain. The liquid level can be set lower for type C than for type S.
Installation type D (U):
Vertical dry installation with base stand
Fig. 4
Permanent installation in a pump room. The pump is bolted to the
suction and discharge pipes by means of flange connections.
Installation types S & C (U):
Submerged installation, portable
Fig. 5
For portable use in pit or temporary installation. The liquid level
can be set lower for type C than for type S.
