•Pump may not be used in potentially explosive
environments!
•Pump and discharge piping are not designed to
hold any weight and may not be used as a step
ladder.
3.3 Remaining Risk
Risk of Injury!
Risk of squeezing or crushing body parts when
installing or removing the pump exists. Proper and
secured lifting tools must be used.
Risk of burns!
The pump must have cooled down sufficiently prior
to commencing any repair, maintenance or installa-
tion.
3.4 Qualification and training of operating
personnel
The personnel responsible for operation, mainte-
nance, inspection and assembly must be adequate-
ly qualified. Scope of responsibility and supervision
of the personnel must be exactly defined by the
plant operator. If the staff does not have the neces-
sary knowledge, they must be trained and instruct-
ed, which may be performed by the machine manu-
facturer or supplier on behalf of the plant operator.
Moreover, the plant operator is to make sure that
the contents of the operating manual are fully
understood by the personnel.
3.5 Safety instructions relevant for operation
•If hot or cold machine components involve
hazards, they must be guarded against acci-
dental contact.
•Guards for moving parts (e.g. coupling) must not
be removed from the machine while in opera-
tion.
•Any leakage of hazardous (e.g. explosive, toxic,
hot) fluids (e.g. from the shaft seal) must be
drained away so as to prevent any risk to per-
sons or the environment. Statutory regulations
are to be complied with.
•Hazards resulting from electricity are to be
prevented (see for example, the VDE Specifica-
tions and the bye-laws of the local power supply
utilities).
•The pumps’ stability against falling over is not
ensured unless it is properly mounted onto the
tank.
•The female threads on the motor MUST NOT be
used to lift the entire pump and motor assembly.
3.6 Safety instructions relevant for mainte-
nance, inspection and assembly work
Any work on the machine shall only be performed
when it is at a standstill, it being imperative that the
procedure for shutting down the machine described
in this manual be followed.
Pumps and pump units which convey hazardous
media must be decontaminated.
On completion of work all safety and protective
facilities must be re-installed and made operative
again.
Prior to restarting the machine, the instructions
listed under “Start up” are to be observed.
3.7 Signs on the pump
It is imperative that signs affixed to the machine,
e.g.:
•arrow indicating the direction of rotation
•symbols indicating fluid connections
be observed and kept legible.
3.8 Unauthorized alterations and production
of spare parts
Any modification may be made to the machine only
after consultation with the manufacturer. Using
spare parts and accessories authorized by the
manufacturer is in the interest of safety. Use of
other parts may exempt the manufacturer from any
liability.
4 Transport and storage

BE3450 Edition 01/2023 Page 5 of 11
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. There-
fore pipe bends should be used, not pipe angles!
The pipework must be qualified for occuring hy-
draulic pressure.
ATTENTION
Maximum tightening torque for piping connec-
tions is 200 Nm!
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 cannot be touched!
5.2 Electric wiring
All service work must be carried out by quali-
fied service personnel. Pump must be discon-
nected 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 nameplate.
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 accord-
ing to the wiring diagram shown inside the
terminal box cover. (Please see above sample
wiring diagrams)
Wiring diagram e.g.
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.
ATTENTION
When Variable Frequency Drives are used interfer-
ing signals might occur.
Non-sinus shaped supply voltage from a variable
frequency drive might result in elevated motor
temperatures.

6 Start up / Shut down
6.1 Start up
ATTENTION
Switch off at the mains.
After connection the electrical wires, close the
terminal box. Briefly start the motor (max. 30 sec.)
and check the rotation according to the arrow on
the top of the motor.
If the direction is incorrect change over two of the
power leads.
6.2 Shut down
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!
Open terminal box and disconnect the power leads.
Empty out the pump.
7 Operation
Liquid level
According to the drawing shown below, the maxi-
mum liquid level must stay about 30 mm below the
mounting flange, also ensure that the minimal liquid
level for the STA pump is 150 mm before starting
up the motor.
If the pump should lock up and cease, shut
pump down (see 6.2) and disconnect from
power supply. Pump must be uninstalled and
removed from the system prior to its repair.
Attention! Potential Risk of Burning!
Surface temperatures above 50°C do occur
during regular operation, i.e. on the surfaces of
the motor and bearing housing.
It must be insured that the pump has cooled
down sufficiently prior to performing any repair
or maintenance work.
8 Servicing and Maintenance
ATTENTION
The surface of the motor must be kept free of dirt.
The motor shaft is spinning in permanently greased
ball bearings (with special grease and increased
bearing play) and does not require any special
maintenance.
