3 SAFETY
3.1 General safety warnings
Improper use of pumps and high pressure systems as well as
non-compliance with installation and maintenance standards
can cause serious damage to people and/or property.
Anyone assembling or using high pressure systems must
possess the necessary competence to do so, knowing the
characteristics of the components that will assemble/use and
take all precautions necessary to ensure maximum safety in all
conditions of use. In the interest of safety, both for the Installer
and the Operator, no reasonably applicable precaution should
be omitted.
3.2 Essential safety in the high pressure system
1. The pressure line must always be provided with a safety
valve.
2. High pressure system components, particularly for systems
that operate primarily outside, must be adequately
protected from rain, frost and heat.
3. The electrical control system must be adequately
protected against sprays of bentonite and must meet
specic regulations in force.
4. The high pressure pipes must be properly sized for
maximum operating pressure of the system and always
and only used within the operating pressure range
specied by the Manufacturer of the pipe itself. The same
rules should be observed for all other auxiliary systems
aected by high pressure.
5. The ends of high pressure pipes must be sheathed
and secured in a solid structure, to prevent dangerous
whiplash in case of bursting or broken connections.
6. Appropriate protective casing must be provided in pump
transmission systems (couplings, pulleys and belts,
auxiliary power outlets).
3.3 Safety during work
The room or area within which the high pressure system
operates must be clearly marked and prohibited to
unauthorised personnel and, wherever possible, restricted or
fenced. Personnel authorised to access this area should rst
be instructed how to operate within this area and informed
of the risks arising from high pressure system defects or
malfunctions.
Before starting the system, the Operator is required to verify
that:
1. The high pressure system is properly powered, see
chapter9 par.9.5.
2. The pump suction pipe must be free from blockage of any
origin. We recommend use of: a solid waste storage tank.
3. Electrical parts are adequately protected and in perfect
condition.
4. The high pressure pipes do not show signs of abrasion and
the ttings are in perfect order.
Any fault or reasonable doubt that may arise before or
during operation should be promptly reported and veried
by qualied personnel. In these cases, pressure should be
immediately cleared and the high pressure system stopped.
3.4 Rules of conduct for the use of lances
1. The operator must always place his safety and security
rst, as well as that of others that may be directly aected
by his/her actions, or any other assessments or interests.
The operator's work must be dictated by common sense
and responsibility.
2. The operator must always wear a helmet with a protective
visor, waterproof gear and wear boots that are appropriate
for use and can ensure a good grip on wet oors.
Note: appropriate clothing will protect against sprays of water
but not from direct impact with jets of water or very close sprays.
Additional protections may therefore be necessary in certain
circumstances.
3. It is generally best to organise personnel into teams of at
least two people capable of giving mutual and immediate
assistance in case of necessity and of taking turns during
long and demanding operations.
4. The work area jet range must be absolutely prohibited to
and free from objects that, inadvertently under a pressure
jet, can be damaged and/or create dangerous situations.
5. The water jet must always and only be pointed in the
direction of the work area, including during preliminary
tests or checks.
6. The operator must always pay attention to the trajectory
of debris removed by the water jet. Where necessary,
suitable guards must be provided by the Operator to
protect anything that could become accidentally exposed.
7. The operator should not be distracted for any reason
during work. Workers needing to access the operating area
must wait for the Operator to stop work on his/her own
initiative, after which they should immediately make their
presence known.
8. It is important for safety that all team members are always
fully aware of each other's intentions in order to avoid
dangerous misunderstandings.
ENGLISH
19
9. The high pressure system must not be started up and run
under pressure without all team members in position and
without the Operator having already directed his/her lance
toward the work area.
3.5 Safety during system maintenance
1. High pressure system maintenance must be carried out
in the time intervals set by the manufacturer who is
responsible for the whole group according to law.
2. Maintenance should always be performed by trained and
authorised personnel.
3. Assembly and disassembly of the pump and the various
components must only be carried out by authorised
personnel, using appropriate equipment in order
to prevent damage to components, in particular to
connections.
4. Always only use original spare parts to ensure total
reliability and safety.

7 OPERATING INSTRUCTIONS
The KF50M pump has been designed and developed
to operate in environments with atmospheres that
are not potentially explosive and with uids with a
high percentage of bentonite, whose recommended
maximum value of density is equal to ~45 sec.
Marsh cone and at a maximum temperature of 40°C.
Other liquids can be used only upon formal approval
by the Technical or Customer Service Departments.
7.1 Bentonite temperature
The maximum permissible bentonite temperature
is 30°C. However, the pump can be used with
bentonite up to a temperature of 40°C, but only for
short periods. In this case, it is best to consult the
Technical or Customer Service Departments.
7.2 Maximum pressure and ow rate
The rated specications stated in our catalogue are the max.
that can be obtained by the pump. Independently of the
power used, the maximum pressure and rpm indicated in the
specication label can never be exceeded unless upon prior
formal authorisation by our Technical or Customer Service
Departments.
7.3 Minimum rotating speed
Any rotating speed other than that indicated in the
performance table (see chapter5) must be expressly
formally authorised by our Technical or Customer Service
Departments.
7.4 Sound emission
The sound pressure detection test was performed according
to Directive 2000/14 of the European Parliament and Council
(Machinery Directive) and EN-ISO 3744-1995 with class 1
instrumentation.
A nal detection of sound pressure must be performed on the
complete machine/system.
Should the operator be located at a distance of less than 1
metre, he will have to use appropriate hearing protection
according to current regulations.
7.5 Vibration
The detection of this value shall be carried out only with the
pump set up on the plant and at the performance declared by
the customer. Values must be in accordance with regulations.
7.6 Brands and types of oils recommended
The pump is supplied with oil suitable for room temperatures
from 0°C to 30°C.
Some types of recommended oil are indicated in the table
below, these oils have additives to increase corrosion
resistance and fatigue resistance (DIN 51517 part 2).
Alternatively you can also use Automotive Gear SAE 85W-90
oil for gearing lubrication.

Using the oil dipstick pos., Fig.3.
The correct checking of the oil level is made with the pump
not running, at room temperature. The oil change must be
made with the pump at working temperature, removing: the
oil dipstick, pos., and then the plug pos., Fig.3.
The oil check and change must be carried out as indicated in
the table in Fig.14 chapter11.
The quantity required is ~3.8 litres.

9 PUMP INSTALLATION
9.1 Installation
The pump must be xed horizontally using the M16x1.5
threaded support feet. Tighten the screws with a torque of 210
Nm.
The base must be perfectly at and rigid enough as not to
allow bending or misalignment on the pump coupling axis/
transmission due to torque transmitted during operation.
The unit cannot be xed rigidly to the oor but must
interposed with vibration dampers.
For special applications contact the Technical or Customer
Service Departments.
A lifting bracket is mounted on the pump for easy installation,
as per the gure below.
Should it be necessary to disassemble it, to avoid the entrance
of dirt in the front part of the casing, close the threaded hole
with the cap provided.
Replace the oil lling hole closing service plug
(red) positioned on the rear casing cover. Check
the correct quantity with the oil dipstick.
The oil dipstick must always be reachable, even
when the unit is assembled.
The pump shaft (PTO) should not be rigidly
connected to the propulsion unit.
The following types of transmission are
recommended:
- Hydraulics by ange, for proper application
consult with our Technical or Customer Service
Departments.
- V-belts.
- Cardan-shaft (comply with manufacturer's Max.
recommended working angles).
- Flexible joint.
9.2 Rotation direction
The rotation direction is indicated by an arrow located on the
casing near the drive shaft.
From a position facing the pump head, the rotation direction
will be as in Fig.5.
LH SIDE
clockwise
RH SIDE
anticlockwise
Fig.5
9.3 Version change
The pump version is dened as right when:
Observing the pump facing the head side, the pump shaft
must have a PTO shank on the right side.
The pump version is dened as left when:
Observing the pump facing the head side, the pump shaft
must have a PTO shank on the left side.
Note. The version shown in Fig.5 is right.
The version can only be modied by trained and
authorised personnel and carefully following the
instructions below:
1. Separate the hydraulic part from the mechanical
part as indicated in chapter2 par.2.2.1 of the
Repair manual.
2. Turn the mechanical part 180° and reposition
the rear casing cover in such a way that the
oil dipstick is turned upward. Reposition the
lifting bracket and relative hole closing plugs
in the upper part of the casing. Finally, properly
reposition the specication label in its housing
on the casing.
Make sure that the lower casing draining
holes in correspondence with the pistons are
open and not closed from the plastic plugs
provided for the previous version.
3. Unite the hydraulic part to the mechanical part
as indicated in chapter2 par.2.2 of the Repair
manual.
9.4 Hydraulic connections
In order to isolate the system from vibrations produced by
the pump, it is advisable to make the rst section of the duct
adjacent to the pump (both suction and outlet) with exible
piping. The consistency of the suction section must be such as
to prevent deformations caused by vacuums produced by the
pump.
9.5 Pump supply
A positive head of at least 0.20 metres is required for the best
volumetric eciency, to be increased with increasing uid
density.
For the priming conditions see the chart in
par.9.8.
ENGLISH
23
9.6 Suction line
For a smooth operation of the pump, the suction line should
have the following characteristics:
1. Minimum internal diameter for pipes of length less than 8
m. 1”1/2.
The pipe must be rigid enough to avoid self-constriction
caused by the pressure drop.
Localised restrictions should be avoided
along the run of the duct, as these can cause
load losses resulting in cavitation. Avoid 90°
elbow bends, connections with other piping,
constrictions, counterslopes, inverted U- curves and
T-connections.
2. With a layout that is set in such a way to prevent
cavitation.
3. Completely airtight and constructed to ensure sealing
over time.
4. Prevent that pump stopping causes emptying, even
partial.
5. Do not use 3 or 4-way hydraulic ttings, adapters, swivel
joints, etc. as they could jeopardise pump performance
due to excessive head losses.
6. Avoid use of base valves or other types of unidirectional
valves.
7. Do not recirculate by-pass valve discharge directly into
suction.
8. Provide for proper guards inside the tank to prevent that
bentonite ow from the bypass and the tank supply line
can create vortexes or turbulence near the pump supply
pipe port.
9. Make sure the suction line is thoroughly clean inside
before connecting it to the pump.
9.7 Outlet line
For the correct laying of the outlet line, the following
installation rules must be followed:
1. The internal diameter of the pipe must be sucient to
ensure correct uid velocity.
2. The rst section of the line connected to the pump outlet
must be a exible hose, in order to isolate the vibrations
produced by the pump of the rest of the system.
3. Use high pressure pipes and ttings to ensure high safety
margins in all operating conditions.
4. Use pressure gauges suitable to withstand pulsating loads
typical of the plunger pumps.
5. During the design stage, keep in mind the line load losses
which result in a drop in pressure during use with respect
to the pressure measured on the pump.
6. For those applications where pulses produced by the
pump on the outlet line may prove harmful or unwanted,
install a pulsation dampener of sucient size.

9.9 V-belt transmission
The pump can be controlled by a V-belt system.
For this pump model, we recommend use of 4 XPB belts
(16.5x13 serrated). Use an XPC prole only for long durations.
Both the characteristics and transmissible power of each
belt can be veried in the diagram in Fig.7, in relation to the
number of rpm normally declared by the manufacturer.
Minimum duct pulley diameter (on pump shaft): ≥250mm.
The radial load on the shaft must not exceed 7500N
(value necessary for Layout denition). The transmission is
considered adequate if the load is applied to a maximum
distance a=40mm from the shaft shoulder (P.T.O) as shown in
Fig.10.
For dimensions diering from those specied
above, contact our Technical or Customer Service
Departments.
Fig.7
9.10 Transmission denition
To prevent irregular radial loads on the shaft and the relative
bearing, follow these directions:
a) Use pulleys with V-belts with the size of the groove
required/recommended by the manufacturer of belt used.
In the absence of directions, follow Fig.8 and the table in
Fig.9.

Do not use laminated V-belts. Fig.9
b) Use high performance belts – for example XPB instead of
SPB – as a lower quantity of belts for the same transmitted
power may be necessary and a consequent shorter
resulting distance compared to the shaft shoulder (P.T.O)
“a“ of Fig.10.
Shaft shoulder
(P.T.O.)

c) Pull the belts according to manufacturer instructions.
Excessive pulling can cause reduced bearing life and wear
out the pulley prematurely. Pulling depends on dierent
variables as indicated in point.9.11.
d) Belt length has a natural tolerance ≥ ± 0.75%. For this
reason, the 4 belts must be purchased as a pair.
e) Follow the direction of the belt pull as shown in Fig.9 for
other needs, contact our Technical or Customer Service
Departments.
f) Take care of the alignment of the driving pulley and driven
pulley grooves.
ENGLISH
26
9.11 Denition of static pull to apply on belts
Static pull depends on:
a) The wheelbase between the two pulleys (belt length).
b) The load due to static pull of the belt.
c) The number of belts.
d) The winding angle of the smallest pulley.
e) Average speed.
f) Etc.
Values of the static pull to be applied can be obtained from
the diagram in Fig.11 for belts with a XPB prole in relation to
the wheelbase.
te = Belt bendmm
Lf= Wheelbasemm
Fig.11
Conclusion: with a wheelbase of 600mm and with a
dynamometer, loading the belt branch with 75 N as indicated
in Fig.12, a "te" bend of approximately 10.8mm is obtained.
Lf = Wheelbase
te = Belt bend
Fe = 75 N Dynamometer load
Fig.12
Note1.Unless otherwise stated by the supplier of the belts,
control of proper pull and its relative re-tensioning should be
performed after no less than 30 minutes of motion necessary
for the normal adjustment of the belts. Best performance and
durability will be achieved with proper tensioning.
Note2.In case of necessity or for routine maintenance, never
replace a single belt but the complete set.
10 START-UP AND OPERATION
10.1 Preliminary checks
Before start-up, ensure that:
The suction line is connected and pressurised
(see par.9.4 - 9.5 - 9.6) and the graphs in par.9.8.
1. The suction line ensures a hermetic seal over time.
2. Any shut-o valves between the supply source and
the pump are fully open. The outlet line during is free
discharge, to permit air present in the pump head to come
out quickly and therefore favour fast priming.
3. All suction and outlet ttings and connections are
properly tightened.
4. The coupling tolerances on the pump/transmission axis
(half-joint misalignment, Cardan joint tilt, belt pulling,
etc.) remain within limits required by the transmission
manufacturer.
5. Oil in the pump casing is at level, veried with a dipstick
(pos., Fig.13) and exceptionally with a level indicator
(pos., Fig.13).
Fig.13
In case of prolonged storage or long-term
inactivity, check proper functioning of the
suction and outlet valves.
10.2 Start-up
1. At rst start-up, verify that the rotation direction and the
supply pressure are correct.
2. Start-up the pump without any load.
3. Check that the supply pressure is correct.
4. Check that the rotation rpm during operation does not
exceed the nominal rpm of the pump.
5. Let the pump run for a period of no less than 3 minutes,
before putting it under pressure.
6. Before each pump stop, reset pressure by means of the
control valve or with any relieving devices and reduce to a
minimum rpm (activation with combustion motors).

If the pump is temporarily not going to be used, in
order to prevent stiening or corrosion caused by
the uids being pumped, it is strongly recommend-
ed to ush all the components inside the head.
To increase the component life of hydraulic parts,
wash the parts with fresh water at the end of the
working day
12 PUMP STORAGE
12.1 Long-term inactivity
If the pump is started for the rst time after a long
period from the date of shipment, before operation
check the oil level, inspect the valves as specied in
chapter 10, then follow described start-up procedures.
12.2 Method for lling pump with anti-corrosion
emulsion or anti-freeze solution
a) Make sure the connecting pipe is clean.
b) Fix the suction pipe to the diaphragm pump, open the
pump suction connection and attach the pipe between it
and the diaphragm pump.
c) Fill the container with solution / emulsion.
d) Insert the free ends of the suction pipe and the high
pressure exhaust pipe inside the container.
e) Switch on the diaphragm pump.
f) Pump the emulsion until it exits from the high pressure
exhaust pipe.
g) Continue pumping for at least another minute. The
emulsion can be strengthened if necessary by adding Shell
Donax for example to the solution.
h) Stop the pump, remove the pipe from the suction
connection and close with a plug.
i) Remove the hose from the high pressure exhaust. Clean
and grease and plug both pipe connections.
13 PRECAUTIONS AGAINST FROST

too high - see graph in par.9.8.
- No suction bentonite.
- Valves are blocked.
- The outlet line is closed and does not allow air
present in the pump head to come out.
The pump pulsates irregularly:
- Air suction.
- Insucient supply.
- Bends, elbow bends, ttings along the suction
