2.3 Operating conditions

The SL1, SLV pumps are designed for intermittent
operation (S3). When completely submerged in the
pumped liquid, the pumps can also operate
continuously (S1). See section
Installation depth
Maximum 10 metres below liquid level.
Operating pressure
Maximum: 6 bar.
Intermittent operation
Maximum 30 starts per hour.
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 (maximum 15 minutes) a
temperature of up to 60 °C is permissible (non-Ex
versions only).
Warning
Explosion-proof pumps must never pump
liquids with a temperature higher than 40
°C.
Density of pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than that of water, use
motors with correspondingly higher outputs.

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.
Warning
Always lift the pump by its lifting bracket or
by means of a fork-lift truck if the pump is
fixed to a pallet. Never lift the pump by
means of the motor cable or the hose/pipe.
The polyurethane-embedded plug prevents water
from penetrating into the motor via the motor cable.

3.2 Storage

During long periods of storage, protect the pump
against moisture and heat.
After a long period of storage, the pump must 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 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. 3.
