a) without taper bush
1A.a Fit the coupllng on the motor shaft by using a threaded bar
with S dia. (TAB. A 1 and A2) as shown in FIG. 1a, and
using 2 wrenches (hold a to avoid shaft rotatlon, and tum b
to draw the coupling on to the motm shalt),
1,5.a For a correcl assembly, lubricate the connecting surfaces
wlth oil 01' antiseizlng paste, For hot mouniing (not
recommended), do not overcome a temperature of 90°C,
Wllich causes Irreparable damages to oil seals,
b) with taper bush
1.4. In case the bush is not provided with keyway (ílem 50 or 51
-FIG. 1b), remove the key from motor or gearbox shaft
(reverse mounting).
1.5.b Carefully clean all surfaces contacting the bush by oil,
grease, etc., possibly usmg solvent, whether they belong to
motor, gearbox 01'fluid coupling.
1.6.b Fit the bush on the motor or gearbox shaft, intoducing a
screwdriver into the axial cut to make mounting easier;
assure that bush goes as far as the shaft shoulder.
For KRG series, fit half coupling (item 29 -FIG. 4) on driven shaft, taking care that the shaft end does not protrude beyond face X.
Fit the fixing screw and the washer (items 25 and 26 for KR models; items 26 and 27 for KSD models) holding the motor or the gearbox
shaft still; lock the fixing screw with a torque wrench, respecting the torque reported in TAB. A 1 and A2.
Only for 13/15 KR KSD models (FIG. 3): fit the allan screw (item d) with flat washer (item e). Holding the motor or gearbox shaft
with a 38 mm wrench b 01'1the end c, lock the allan screw with a torque wrench a, respecting the torque reported in TAB. A2.
N.B.: For a correct assembly with the taper bush, strictly apply to the prescribed locking torque.
1.7
1.8 For KRG models, lock and peg the driven machine, positioning the motor as far as the gap K (FIG. 4) between the half couplings
reaches the Indicated values listed in TAB. C. The error on radius can be checked with a gauge and a straight-edge (FIG. 4): the
angular gap with a feeler, by rotating the coupling at 4 points 90° apart: the errors should not exceed those listed in TAB. C.

TI'ansfluld fluld coupllngs are no! supplled wlth 011
Therelore 11IS necessary to achleve the lollowlng pracedure:
2.1 Positlon the coupllng axls horizontally (FIG. 6). turn I1until the
X mark cast Into the houslng gets al tlle top vertical (maxlmum
fill). so that tlle 011plug (item 13) Is Inclined as shown III the
plcture
FIIIwlth 011untll it overflows out 01 the filler hole. Whlle fllllng,
gently rack the coupllng on its axls to make sure all air excess
IS vented out of the clrcult, 01', If posslble. remove also tlle cap
located In correspondence on the other rotor. The quantltles to
be Intraduced are those reported in TAB. 01.
Screw the cap (or both caps) at the prescribed torque (TAB.
E) and make sure no leakages occur; otherwise use thread
sealant on filler plug tllreads.
The líllings marked X-1-2-3-4 may be chosen by the opel'ators
to meet the be sI performance In terms 01 start-up and steady
runnlng operatíon.
With the maxlmum fill X a conditlon 01 mlnlmum slip and
maxlmum performance Is achieved: the startlng torque !
nominal torque ratlo gets higher (values generally comprised
between 1.8 and 2.2) decreaslng the 011quantlty Inslde the
coupling (fII11-2-3-4), the opposite result Is obtained.
HIgh slip causes overheating of 011contalned in the worklng
circuit, wlth a consequent decrease IIIoverall performance.
For normal operatlng conditions, use only ISO HM 32 (01'
equivalent SAE 10W) 011 types listed in TAB. O. At low
amblent temperatures, use ISO HM 10 (01' equivalen!
SAE 5W) ol!.
For vertical mounted appllcatlons, the coupllngs
recommended 011fllls are reported in TAB. 01.

Fluid couplillgS Wltll delayed IIIIchambel (CK series) have the mal n
purpose ot reduclng tlle startíng torque / nominal torque ratlo to
values up to 1.6 . Thls aspecl Is Improved by furtherly enlarglng the
delayed flll chambel (CCK series) up to values of 1.3 of the above
ratío
2.8 The startíng torque Ilmítatlon can be achieved by reducíng the
oil quantlty ínto the worklng clrcult (till 2-3-4) without
IIlcreaslng the slip value a! rated speed. In standstill positlon,
the delayed lill chambel actually COlltalllS par! 01 the oil II11that
Ilows to the working clrcuit durlng start up.
2.9 The 011 passes Irom the delayed IIII chamber to the workíng
clrcuit tllrough calibrated orifices (FIG. 7) oWlng to
centnlugal lorce. Starting Irom slze 21 K, such orillces
dlameters can be modílied even when the coupllng is already
assembled, slmply by replacing a calibrated bleed plug (item
b) screwed IIlto the valve (Item 57). When reassembling the
valve, always remember to flt the copper seal (Item 58) and
make sure no leakages occur.
This technical solution allows a very simple and easy
operation, to be achieved in a very short time and (what is
more important) without disassembling the fluid coupling.
210 For each starting torque ! nominal torque ratío, Transfluld can
give the exact oíl lill. The Iluíd coupllngs with a delayed fill
chamber are generally foreseen with fill 2 (TAB. 02), while
the ones equlpped wlth a double delayed fill chamber with
fill 3 (TAB. 03).
As fluid couplings are supplied without 011, lollow the
instructlons reported at par. 2.1 - 2.2 - 2.3 -2.6.
211 For vertical mounted appllcatlons, the coupllngs
recommended oíl fills are reported In TAB. 02 and 03. Oue to
delayed lill chamber peculiarity, for vertical mounting the
chamber must be downward.

3. OPERA TION ANO MAINTENANCE
3.1 The normal operaling procedures have lo be carried on
keeping balance and temperature under control.
l\jol 10 damage Ihe coupling seals, lemperalure musl no!
overcome 90'C. For hlgher values, all Ihe seals bul Ihe rolaling
ones In Viton (items 15 and 20), have lo be made of a special
material 100.
As eVldenced in TAB. F where the causes and the relalive
remedies are reported, a high temperature value may be
caused by the following condillons:
a) Insufficlenl oil fill
b) Higher absorbed power Ihan motor rated power
C) HIgli Clmbíenl lemperature
d) High starting frequency per hour
e) Excesslve slartlng time
f) Too many consecutive start-ups
g) Inadequate aír ventilation due to cover guardo
TRANSFLUID can supply all operating
data upon request.
3.2 After the first 20 days operalion, check the
oil fill (this operation to be carried out
with cold oil), the tightening of the screws,
the molor and the driven machine.
3.3 Repeal Ihe above checks every 6 months
-For the KRG models, check the gap K
(TAS. C) of the elastic coupling. If the
torsional gap is excessive (about 2°),
replace the rubber elements.
3.4 Fluid couplings are supplied with fusible
plug al 145"C (120°C, 175°C and 198°C
settíngs are available upon request) as
shown in FIG. 14.
If the fusible plug blows al regular intervals
during normal service, then checks a), f) in
par. 3.1, and relalive T AS. F should be
considered.
3.5 In case the switching pin or the electronic
overload controller are mounted, check
that the dístances shown in FIG. 9 and 11
are wilhin the values imposed during the
assembly phase.
3,6 Oil should be replaced after 4000 hours

5. ACCESSORIES
Fluid couplings can be equipped, beyond the standard fusible plug.
with similar safety devices avoiding oil to escape, and that, in the
case 01 the electronic overload controller, can manage a lew more
palameters too.
The luslble plug is present as an element 01 further safety though
being set al a highel' temperature value.
51 SWITCHING PIN directly fitted 10 the couplíng covel plate
(FIG.9).
The electrical connection of the switch must have a lower
voltage than 230 V and a max current of 6 A (electrical
scheme details reported in FIG. 10).
Fllmly position the cam mounted lelay on its support, so tha!
the dlslance lrom the end 01 the switching prn is 6 mm.
11IS very imporlant to be within such a distance because, in
case the device is activated, the pln comes out owing 10
centrifugal lorce and intelcepts Ihe cam, switch es it on and
gives a conveníent outpul signal (to be used as an alarm or a
blocking impulse for the motor).
Notice that, in the configuratlon 01 an external driving impellel
the sWltching pin works in every condition; while, with an
external dliven Impellel' it can be correctly switched on only in
case of a slip increase due to overload 01 eccesslve load
tOlque absorption.

5.2 ELECTRONIC OVERLOAD CONTROLLER, formed by a
proximity sensor and a speed controller. It detects the output
speed of the fluid coupling continuously.
When the load torque increases, slip increases too and speed
consequently decreases.
II the speed reduces down to the set threshold far a longer
time than specified, thls is signalled by the intervention 01 the
internal relay.
The said electronic device can be mounted on all fluid
couplings where not installed O.E.M. It is only needed to
replace 2 bolts positioned at 180' around the external crown
(as shown in FIG. 11) with 2 special ones having a longer
screw and nut.
As shown in FIG. 11, it is necessary to position the proximity
sensor in line with the 2 bolts at 180°, at a lower distance than
5 mm, while the controller can be fitted in the most convenient
place, chosen by the user, within a maximum distance of 20 m
(making the proximity connecting wire adequately longer).
Before connecting to the electrical power supply, always
verify the voltage.
The electrical connections have to be achleved according to
the scheme reported in the detailed instructions 01 the same
electronic device, setting and/or adjusting all the functions on
the control panel, as shown In FIG. 12.
a) Blind time lor starting TC, wlth a screw regulation up to 120
s, avoiding the intervention of the alarm during the starting
phase.
b) Speed range DS, by means 01 a Dip-Switch to be
programmed on 5 and 8 positions, setting relay condition,
proximity type, reset system, acceleration or deceleration.
c) Speed threshold SV to be screw regulated from 1 to 10.
The value 10 corresponds to full range set with dip-switch.
d) Reset R, locally executable with a manual switch or remote
connections.
e) Delay time T setting screw regulation up to 30 s. This
lunction delays possible alarms caused by sudden torque
variations.
The lunction of the timers respect to the state of the relays is
diagrammed in FIG. 13.
Leds (FIG. 12) permitting to keep some vital lunctions under
control are al so present on the panel:
1) Speed level overtaken SS with a red light switching on as
soon as the set threshold is overcome.
g) Red alarm A lighting up when the internal relay switch es
on.
h) Green supply led ON pointing out that the device is
electrically supplied.
N.B.: For further details concerning electronic features and
connections, refer to the specific instructions supplied
with the device.
