8.3 Surface Pumps
a
CAUTION – This graphic is an
exemplary pump system layout diagram
and for ease of understanding only. For
system installation and wiring read and
follow the detailed instructions given in
this manual.
A higher content will cause excessive wear within the
pump and reduce the pump’s life span considerably.
Any pump that is blocked by sand will not be covered
by warranty.
8.2.9.3 Flow sleeve
All LORENTZ PSk3 submersible pumps are designed
for the use of water with a temperature between 0°C
and 30°C.
The minimum liquid velocity past the motor is
0.16 m/s.
a
CAUTION – Where the stated liquid
velocity cannot be achieved, a ow sleeve
must be installed.
For the maximum recommended sand content,
before any signicant detrimental eects occur,
check chapter "4.3 Technical requirements for the
pumps" on page 13.

8.2.9 Additional Features
8.2 .9.1 Safety Rope
We recommend the use of a safety rope as a loss
insurance. If the pipe breaks because of start-
up torques of the motor, too much weight, pipe
corrosion or wrong installation, a safety rope can
prevent the total loss of the pump system and
damage to the well.
Choose a safety rope that can handle the weight of
the whole installation and the water inside the pipes.
The rope material must be water-resistant. Near
the well head the rope needs to be UV-resistant or
protected from sunlight.
a
CAUTION – Do not use a nylon rope.
Nylon is known to absorb water over time
which will weaken the rope.
8.2.9.2 Plastic pipes
When the pipes are strong enough, the use
of plastic pipes is possible. If you are not sure
about the strength of your pipes contact the pipe
manufacturer.
a
CAUTION – The pipes must be strong
enough to hold the whole weight of
the pump, the motor, the pipe system
and the water in the pipes. It must also
withstand the water pressure generated
by the total dynamic head.
CAUTION – When using plastic pipes
you should always use a safety rope.
