2 Description of product
2.1 General description of the pump
Pumps of this type are multi-stage rotary pumps.
Series TH/STH use closed impellers in order to
minimizing power consumption and to optimize
hydraulic pump efficiencies. In addition, the TH/STH
series offers high pressures at short immersion
depths.
The pump shaft and the motor shaft are connected
by a coupling. The pump shaft is sealed by a rotat-
ing mechanical seal. The pump is protected again
impurity by a filter. Pump and motor form a compact
and space-saving unit.
Vertically mounted pumps are equipped with a
mounting flange. The pump end immerses into the
tank and the motor extends vertically above the
tank.
2.2 Intended use
The immersion pumps of the series TH/STH have
been especially developed to supply internally
cooled tools with coolant fluid within the limiting
application in accordance with table 1.
Limit of Application (Table 1)
ATTENTION
The pumps are to be operated within their design
limits. Applications outside of these limits are not
approved. The manufacturer is not responsible for
any damages resulting from use of the pumps in
such applications.

3 Safety instructions
When operating the pump, the safety instructions
contained in this manual, the relevant national
accident prevention regulations and any other ser-
vice and safety instructions issued by the plant
operator are to be observed.
3.1 Hazards in the event of non-compliance
with the safety instructions
Non-compliance with the safety instructions may
produce a risk to the personnel as well as to the
environment and the machine and results in a loss
of any right to claim damages.
For example, non-compliance may involve the
following hazards:
•Failure of important functions of the ma-
chines/plant
•Failure of specified procedures of maintenance
and repair
•Exposure of people to electrical. mechanical and
chemical hazards
•Endangering the environment due to hazardous
substances being released
3.2 Unauthorized modes of operation
•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 adequately
qualified. Scope of responsibility and supervision of
the personnel must be exactly defined by the plant
operator. If the staff does not have the necessary
knowledge, they must be trained and instructed.
which may be performed by the machine manufac-
turer 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 under-
stood by the personnel.
3.5 Safety instructions relevant for operation
•If hot or cold machine components involve haz-
ards. they must be guarded against accidental
contact.
•Guards for moving parts (e.g. coupling) must not
be removed from the machine while in operation.
•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 pre-
vented (see for example, the VDE Specifications
and the bye-laws of the local power supply utili-
ties).
•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 liabil-
ity.
4 Transport and storage
Protect the pump against damage when transport-
ing.
The pumps may only be transported in a horizontal
position and hooks or straps must be attached on
the motor and pump end.
Do not use the pump shaft for connecting any trans-
portation aids such as hooks or straps.
Pumps must be drained prior to their storage.
Store pump in dry and protected areas and protect it
against penetration of foreign bodies.
Always store pump above the freezing point!

BE3914 Edition 12/2019 Page 10 of 16
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 cannot be blocked by
deposits during longer shutdowns.
The leakage is collected in a leakage chamber and
drained off by the leakage hole into the tank. During the
assembling of the pump, be sure that the leakage hole
is free.
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 discon-
nected 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 long term
electrical connection is ensured. Establish a solid
ground connection.
The electrical wiring must be performed ac-
cording to the wiring diagram shown inside the
terminal box cover. (Please see above sample
wiring diagrams)

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
Be sure that the suction hole of the pump body is
immersed about 55 mm in the liquid (min. liquid
level) 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.

11.1 Exchange the rotary mechanical seal:
(S)TH11…(S)TH17
1) Disconnect the pump from the power supply.
2) Loosen the M5 screws and pull out coupling
shield (70). Remove clamp coupling (69.1. 69.2)
and parallel pin (76).
3) Loosen and pull off the hexagon cap nuts (81),
the stud bolt (71) and the pump casing (67) from
the pump unit. Remove pump unit with pump
shaft (52) from the pump body (50).
4) Take off rotating axial face seal unit (74.1-74.5)
and mech. seal washer (66) from the shaft (52)
and clean the shaft. Pay attention to the drilled
hole for the parallel pin (76) that it is without any
bur. Check the sliding surface for the rotary
shaft seal (73) for any damage.
5) Remove complete seal (74.6. 74.7) from the
pump body (50) and clean the seat.
6) Mounting of the new axial face seal:
Ensure that the sliding surfaces of the ring and
the rotating axial face seal unit are free from
grease and dirt.
Moisten the angle-sleeve (74.7) of the counter
ring lightly with rinse water / (water with wash-
ing-up liquid) and push the unit into the seat of
the pump body (50).
Slide the mech. seal washer (66) first and then
the axial face seal (74.1-74.5) onto the pump
shaft (52).
7) Lubricate lightly the lip of the rotary shaft seal
(73) and push it into the pump body (50). Then
insert the pump shaft (52) with the pump unit
through the rotary shaft seal (73).
8) Fit together the coupling clamp (69) with the
parallel pin (76) around the shafts, tighten the
hexagon socket head cap screws (78) with the
serrated lock washer (79) lightly.
Be sure that the key of the motor shaft (4) coin-
cides with the key groove of the coupling clamp
(69.1). Press the pump shaft (52) toward the
motor and tighten the screws.
The distance between the two shaft ends must
be zero.
9) Lubricate the O-ring seal (72) of the pump body
