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.

ATTENTION
Maximum tightening torque for piping connections is
150 ft. lbs. (200 Nm) for NPT 2 ½ and 130 ft. lbs.
(170 Nm) for NPT 2 !
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.
Non-sinus shaped supply voltage from a variable
frequency drive might result in elevated motor tem-
peratures.
