5 Installation and Connection
5.1
Mechanical installation
During any assembly or disassembly process the
pumps must be secured against tipping trough ropes
for example at all times.
Pumps must be mounted securely. Piping, tank and
pumps must be mounted without any tension.
The inlet is at the bottom of the immersed pump body.
The distance between the inlet and the tank bottom
must be so large that the inlet can not be blocked by
deposits during longer shutdowns.
To obtain the full flow rate it is recommended to
choose for the pipework the nominal bore diameter of
the pumps cross section for connection. Therefore
pipe bends should be used, not pipe angles!
The pipework must be qualified for occuring hydraulic
pressure.

When installed the space around the pump must
be large enough to provide sufficient cooling of
the motor.
Do not prop up the pressure line via the joining
socket.

The pump must be mounted in that way that
rotating parts under the cover of the coolant tank
can not be touched!
5.2
Electric wiring
All service work must be carried out by qualified
service personnel. Pump must be disconnected
from the power source and all rotating parts must
stand still. Reassure that pump is disconnected
from power source and cannot be switched on.
Verify that there is no voltage at the terminal
board!
According to the European Standard EN809 a motor
overload must be installed and properly set to the full
load amps stated on the pump name plate.
It is the responsibility of the machine operator to
decide whether or not an additional emergency switch
must be installed.
5.2.1
Circuit
Tension voltage and frequency must correspond with
the shown specification on the
The pump must be wired so that a solid longterm
electrical connection is ensured. Establish a solid
ground connection.
The electrical wiring must be performed according
to the wiring diagram shown inside the terminal
box cover. (Please see above sample wiring dia-
grams)

There may be no foreign objects such as dirt, particles or
humidity inside the terminal board.
Mount terminal board cover to motor tight against dust
and humidity and close up all unused wiring ports.

When Variable Frequency Drives are used interfering
signals might occur.

quency drive might result in elevated motor tempera-
tures.
