2.3 Operating conditions
The pumps are designed for intermittent operation
(S3). When completely submerged, the pumps can
also operate continuously (S1).
The EF pumps are suitable for pumping effluent and
other liquids with solids up to 30 mm.
Installation depth
Maximum 10 metres below liquid level.
Operating pressure
Maximum 6 bar.
Number of starts per hour
Maximum 30.
pH value
Pumps in permanent installations can be used for
pumping liquids with a pH value between 4 and 10.
Liquid temperature
0-40 °C.
For short periods of maximum 15 minutes, a
temperature of up to 60 °C is allowed. This applies to
standard versions only.
Density of pumped liquid
Maximum 1000 kg/m

3. Delivery and handling
The pump may be transported and stored in a
vertical or horizontal position. Make sure that it
cannot roll or fall over.
3.1 Transportation
All lifting equipment must be rated for the purpose
and checked for damage before any attempts to lift
the pump. The lifting equipment rating must under no
circumstances be exceeded. The pump weight is
stated on the pump nameplate.
The polyurethane-embedded plug prevents water
from penetrating into the motor via the power cable.
3.2 Storage
During long periods of storage, the pump must be
protected against moisture and heat.
After a long period of storage, inspect the pump
before it is put into operation. Make sure that the
impeller can rotate freely. Pay special attention to the
condition of the shaft seal and the cable entry.
3.3 Lifting
When lifting the pump, use the right lifting point to
keep the pump balanced. Place the lifting chain hook
in point A for auto-coupling installations and in point
B for other installations. See fig.
Fig. 4
Lifting points
Explosion-proof pumps must never pump
liquids with a temperature higher than 40
°C.
WARNING
Crushing hazard
Death or serious personal injury
- Always lift the pump by its lifting bracket
or by means of a forklift truck if the
pump is fixed on a pallet. Never lift the
pump by means of the power cable or
the hose or the pipe.
