Installation, Operating and Maintenance Instruction
Under no circumstances may the unit be lifted
on to the motor cable. Do not damage the cable
during transport (do not squeeze, bend or drag).
The cable ends must be kept dry.
Do not stand underneath suspended loads; take
note of the general regulations on prevention of
accidents.
The pump/pump unit must be secured against
tipping over and slipping until it has been fixed
in its final location.

4. Assembly, Operation

4.1 Preparing to install the unit

Necessary equipment for installation
Lifting gear (lifting block or winch). This must be
strong enough to bear the whole weight of the
pump, motor, cable and pressure line when it is
full.
Support clamps. These must also be able to bear
the whole weight of pump, motor, cable and the
pressure line when it is full. Two identical pairs of
support clamps are required for installation.
Voltammeter and
measuring device (e.g. megger) with direct current
(at least 500 V measuring circuit voltage).
Fittings and Hydraulic Equipment
Non-return valve. The non return valve is usually
integrated in the pump delivery casing at pumps
for vertical arrangement. If the pump is to be
installed horizontally or if a pump was expressly
ordered without an integrated non-return valve a
suitable non-return device should be fitted as
close to the pump as possible.
Pressure valve. This is to be fitted in the pressure
line to regulate the discharge.
Pressure gauge with a stop valve. These are to be
fitted between the pump and the pressure valves
to control and regulate operating pressure.
Water level indicator or low water protection.
These are to control and supervise the minimum
water level during operation.
If water levels fluctuate we recommend that you install
a low water protection device. This device monitors
the water level and if it sinks below permitted levels
automatically turns the motor off.

4.2 Setting the Installation Depth

The depth of installation should be set with the help of
the well or bore hole diagram.
The pump unit must not stand on the ground as
it can be damaged by the weight of the pressure
line.
The suction filter of the pump must have minimum
coverage at the lowest service water level. For bore
wells arrange the pump with its suction filter far
enough above the filter pipe that it is certain that no

3.2 Storage

If a pump or unit are to be stored for a long period
before installation or after removal the pump must be
completely emptied. They must be stored in a dry,
frost-resistant room. Protect from damp (especially
cable ends), vibrations and dirt, e.g. by wrapping in
oiled paper. The units must be stored standing (motor
at the bottom). Secure so that it cannot fall over.
Observe the Motor
radiuses, see Motor Operating Instructions.
sand can be sucked in. If, however, the pump is
installed near the filter pipe or below the filter, pipe
sand protection or a flow cover must be fitted.
The motor is cooled using well water. The required
minimum flow speed on the motor outside lagging
must be given during operations. Ensure that the unit
hangs completely free in the water and does not touch
the sand or mud at the bottom of the well.
For narrow bore holes we recommend that you
plumb the bore hole with a dummy which
exactly matches the pump to be sure that the
pump will not get stuck or become damaged.

4.3 Pipes

The unit must hang freely on the pressure line below
the lowest service water level. The carrying capacity
and compression strength of the pipes must be set so
that the weight of the unit including the cable, the
weight of water content and the maximum operating
pressure can be held with certainty.
When lifting the unit out of the well/bore hole
pay special attention to the weight of the full
pressure line!
Submersible pumps with threaded connections may
only be held up against the uppermost pressure
casing when screwing in the pipes to prevent the
pump from turning and becoming damaged. To
prevent the pump coming loose from the pipes the
thread connections
commercially available screw securer (Loctite, Omnifit
or something similar). This also prevents possible
crevice corrosion in the thread connection.
It is important that the flange gasket is centrically
inserted and does not compress the free cross section
of stream. Round off the edges of the flange or the
recesses to avoid damage to the cables. The flange
joints should be secured against loosening.

4.4 Coupling the Motor and Pump

(only when the pump and motor are delivered
separately)
Protect the motor cable from damage.
