2. INSTALLATION
2.1 Installation design
2.1.1 Pump
To obtain the service expected from a MOUVEX pump,
regarding both performance and longevity, it is vital that
the type of pump, its speed and the materials used for its
construction are determined as a function of the pump
output, its installation and operating conditions.
You can contact our Technical Services at any time to
ask for the information you require.
2.1.2 Pipe
Suction pipe length
Length should be as short as possible.
Suction pipe diameter
Diameter must be at least equal to pump port diameter
and even more if required by pumping conditions.
Suction pipe configuration
Check tightness to avoid accidental air intake.

Pipe alignment and supporting
Pump must not support piping nor endure stress resul-
ting from piping weight or dilatation effects. For latters,
expansion loops should be included.
Pipe equipment
• Place valves close to the pump to avoid draining pipe
during maintenance operations. Preferably select full
bore ball or butterfly valves.
Pressure connections on pump suction and discharge
are recommended for settings and controls.
Make sure piping, vessels valves and other installation
devices are carefully cleaned before mounting.
• MOUVEX pumps are self priming. However, if line
emptying should be avoided and/or if suction lift is high,
a foot valve can be added.
• If pumped liquid presents a risk of in pipe solidification
and potential dilatation, low points on the pipe should
be avoided or equipped with drain valve.
• If installation is heated, it must be designed so that fluid
dilatation can evacuate through piping. Therefore fluid
contained in piping must be heated before fluid contained
in the pump. Also check that a heated pump is not iso-
lated by closed valves.
The SL Series pump is a selfpriming volumetric PD
pump. Therefore, the pump must not run on a circuit with a
closed valve. This is valid both for the suction circuit and
for the discharge circuit.
2.2 Orientation of the pump ports
The suction and discharge ports may be oriented in
various positions.
If the ports positions needs to be changed at any time,
see the corresponding paragraph.
2.3 Direction of rotation
When looking at the shaft, the rotation will be clockwise.
When looking at the front cover, the direction of rotation
will be anti-clockwise. An arrow situated on the bearing
housing indicates the correct direction of rotation.
Verification of the correct rotation direction :
Turn the pump the wrong way is not dangerous for the pump.
NOTICE
SL-Series pumps remains drainable whatever
position is chosen for the inlet port, but the
outlet port must be at the bottom (position 4)
to keep the self-draining capability.

2.4 Protection of the pump installation
• Before any start-up, during operation or complete stop-
ping of the pump, make sure the valves are open.
• During stop periods, with the pump full of product,
either the suction or discharge circuit must be left open
to enable expansion or contraction of the pumped pro-
duct through reheating or cooling. If this instruction is
not complied with, The bellows may be damaged and
lead to premate failure.
• The bearing must be ventilate at all times, therefore the
breather mounted on the bearing must be re-used.
Never put the plug on.
• It is possible to have a puncture detection system with
double-walled bellows : an inert gas is maintained under
pressure between the 2 walls and said pressure is perma-
nently monitored. A signal is dispatched immediately should
a wall become punctured. See Instructions 1011-S00.
• The stop time may lead to cooling of the product in the
pump and therefore to an increase in viscosity. If this is
the case, we recommend re-starting the pump at a
speed adapted to this new viscosity (starting pump).
Once the product arrives in the pump at the installation
definition temperature, the pump may run at the speed
specified for this application.
• Protection against excess pressure :
The pump must be protected against excess pressure. It
can be delivered with a pressure switch to carry out this
function.
If protection is provided by a control valve, check that the
system does not generate excess pressure at the bel-
lows (particularly if there are water hammers). Operating
in this way would damage the bellows and shorten their
lifetime.
• Protection against foreign bodies :
The pump and the installation must also be protected
against any risk of damage through the passage of
foreign bodies by mounting a pre-filter at the pump suc-
tion.
In the case of foreseeable clogging of the pre-filter, we
recommend using a vacuum switch to inform the user
of pre-filter clogging. Prolonged running under cavita-
tion may damage the pump.
The largest dimensions of the allowable particles in the
pump are :
• Soft particles : ..............10 mm
• Hard particles : ...............2 mm
• Insulation of the inlet manifold and the front cover :
Different options require the use of tie rods along the
inlet manifold such as turn able suction or jacketed
manifold.
For these designs it is imperative to take the following
precautions :
• insulate the inlet manifold and the front cover when
difference between ambient and pumped product

Hoisting points :
2.6 Unit Assembly
The following instructions apply to pumps delivered with
a bare shaft or for MOUVEX motor-driven pump units (if
the latter have no specific instruction notice).
2.6.1 INSTALLATION OF UNITS
The base below the unit is fundamental to ensuring cor-
rect operation and long service life.
The unit’s base must be flat, level and sufficiently resis-
tant to absorb the stresses caused by the motor-driven
pump unit without deformation (if it is made of concrete,
it must comply with the BAEL 91 standard).
If the unit is fastened using securing lugs or bolts, it must
be carefully wedged to avoid deforming the frame while
the bolts are tightened. A deformed frame would apply
damaging stresses on the pump and the drive mecha-
nism and misalign the coupling, causing vibrations,
noise and premature wear. Ensure that the frame is well
above the floor, except from the support plates.
If the unit is to be used in a food environment, support
plates that allow the unit to be lifted for easier cleaning
are recommended.
Allow, if possible, a clear space of approximately 50 cm
on each side of the motor-driven pump unit (overall
dimensions) to facilitate cleaning and give access if
necessary to the pump, reduction gear and motor faste-
ning nuts. In all cases, the dimensions around the motor-
driven pump unit must be designed to give the space
required for dismantling the pump (if the need arises,
use the values given on the overall dimension drawing).
For staff and equipment protection, the frame includes a
ground connection point that should be used.

2.6.2 ALIGNMENT OF THE MOTOR/PUMP OR
REDUCTION GEAR/PUMP SHAFTS
NEVER START A UNIT IF THE COUPLING ALIGN-
MENT IS INCORRECT. THIS IS A CONDITION OF OUR
GUARANTEE.
REMINDER :
Coupling must never be used to compensate for a misa-
lignment.
To control the alignment between the coupling and the
shaft, use a straight-edge for concentricity and thickness
gauges for angular misalignment (see instructions of the
coupling for authorised values).
The 3 figures below show in detail the operation and the
possible defects :
Controlling the alignment at each stage of the installa-
tion is important to be sure that none of these stages
have generated stresses on the unit or the pump :
• after fastening on the foundations.
• after fastening the pipes.
• after the pump has been operated at the normal
operating temperature.
Where the pumps are supplied assembled as a unit, the
motor and pump shafts have been perfectly aligned in
the factory before delivery, but they must be systemati-
cally controlled on acceptance at the site and realigned
if necessary.
To do this, do not modify the wedging of the various
parts, but check the flatness of the support surface and
use the adjustable foot to clear the frame of stresses that
could affect it.
2.6.3 ELECTIC MOTORS
Check the compatibility of the instructions on the motor
with the supply voltage.
Follow the wiring diagram, use wiring that is appropriate
for the power and be particularly careful about the
contacts which must be well tightened.
The motors should be protected with circuit breakers
and suitable fuses. Connect the regulatory electrical
grounding.
2.6.4 THERMIC MOTORS
Do not forget that these motors are not reversible. It is
absolutely necessary to carefully control the suction and
discharge sides of the pump before connecting the
group to the piping.
Using electric motors is very common now; however, we
strongly advise careful reading of the accompanying ins-
truction manual.

3.1 Noise level
The sound level of a pump is greatly influenced by its
conditions of use. Cavitation and pumping products with
high gas contents generally increases the sound level.
Under the following pumping conditions :
• excluding cavitation
• discharge pressure :
• SLC12 : . . . . 9 bar (130,5 psi)
• SLC18 : . . . . 6 bar (87 psi)
• speed of rotation 450 rpm
• product viscosity of 1 cSt
The sound level reached for the SLC12 / SLC18 pump
in good conditions without the drive is less than 81
dB(A).
3.2 Commissioning
Make sure that the circuit valves are open before star-
ting the pump.
To avoid any risk of polluting the product to be pumped,
rinse the whole installation before starting-up so as to
eliminate any contaminants that may remain in the
piping, tanks etc. at the time of installation.
3.3 Dry running
The SL Series pump is self priming and is capable of
emptying the pipes. To do this, it can run dry for a maxi-
mum duration of 5 minutes.
3.4 Pump stop
So as not to damage the pump, make sure that the
pump is completely stopped before closing the valves.
3.5 Scrapping
The pump must be scrapped in compliance with the
regulations in force.
During this operation, particular care must be paid to the
drainage stages of the pump (pumped product) and of
its transmission (lubricant).
For any pure water pumping during process or
cleaning operations, consult Mouvex imperatively.
3. UTILISATION
2.6.5 CONTROL OF THE SENSE OF ROTATION
This control needs to be done with no liquid pumped
through the pump, and both the suction and discharge
circuits venting to avoid generating unexpected pressure
(at the suction side, for example). This will ensure that
the control will not damage either the pump or the instal-
lation.
Start the pump empty to check that the connections are
good and that the direction of rotation corresponds to the
suction and discharge direction on the installation. If it is
necessary to reverse the direction of rotation, follow the
instructions below :
Three-phase motor : switch any 2 current input wires.
Bi-phase motor : switch two same phase wires.
Single-phase motor : follow the instructions on the notice
supplied with the motor.

4. CLEAN IN PLACE (CIP) &
STERILISATION IN PLACE (SIP)
4.1 General
On-site cleaning (CIP) of an installation is undertaken by
circulating various cleaning solutions through the equip-
ment parts.
An automated CIP system enables :
• Preparation of the appropriate concentrations for the
different cleaning solutions.
• Re-heating of certain cleaning solutions at the opti-
mum temperature.
• Circulation of the different solutions through the equip-
ment parts to be cleaned.
• Rinsing and drying of the equipment parts.
For the most part, automated CIP systems are an inte-
gral part of process equipments.
Before starting CIP and if the process has not been fol-
lowed by a water flush, care must be taken that a mini-
mum of residual products remains in the piping and in the
pump. The SL Series pumps, thanks to their excellent
suction and compression capabilities, enable reducing
the quantities of residual products. This minimises loss
of products, eases cleaning and reduces cycle times.
The SL Series pumps are perfectly adapted to all pro-
cesses necessitating CIP.
The start of CIP must immediately follow the end of the
process to avoid any clogging or untimely drying.
Non-compliance with this instruction may lead to rapid
wear of cylinder and piston.
4.2 CIP circuit recommended
In all cases, the pressure at the pump inlet during clea-
ning must not exceed 3 barg (43,5 psig).
The flow through the pump required for optimal cleaning
is 30 - 35 m3/h.
This flow corresponds to difficult cleaning (sticky and vis-
cous products). It can be reduced for easier types of
cleaning.
4.3 Pumps arranged in series
This type of assembly is preferred in all cases. It ensures
optimal cleaning for the pump and makes use of the spe-
cial design of the SL Series, i.e. the possibility of lifting
the piston with the cleaning product.
As the pressure at the pump inlet is higher than that at
its outlet, the piston lifts from the cylinder and permits
the passage of all the cleaning liquid through the SL
Series pump.
• A centrifuge pump is used for CIP cycles. This pump
is placed upstream of the SL Series pump.
The centrifuge pump must be installed in series with
the SL Series pump.
It is preferable not to run the SL Series pump during CIP
although low speed (< 100 rpm) is acceptable by alter-
nating start/stop operation.
• In certain cases, the flow of the cleaning liquid requi-
red for the installation is higher than that recommen-
ded for cleaning the pump. In this case, a bypass must
be used.
The bypass valve is adjusted to divide the flow bet-
ween the circuit flowing through the SL Series pump
and the bypass circuit.
SL SERIES PUMPS MUST NEVER BE USED AS
CIP PUMPS.

4. CLEAN IN PLACE (CIP) &
STERILISATION IN PLACE (SIP) (continued)
It is preferable not to run the SL Series pump during CIP,
although low speed (< 100 rpm) is acceptable by alter-
nating start/stop operation.
• In certain cases, the cleaning pressure required for the
installation is higher than 3 barg (43,5 psig). In this
case, the use of a bypass is required and cleaning is
done in 2 steps.
Cleaning the pump :
The cleaning flow should be limited during the cleaning
of the SL pump to ensure a maximum pressure of 3 barg
(43,5 psig) at the SL pump inlet.
It is preferable not to run the SL Series pump during CIP
although low speed (< 100 rpm) is acceptable by alter-
nating start/stop operation.
Cleaning the installation :
During this operation, the valve system used must ensu-
re that no flow can pass through the pump so that the SL
Series pump does not rotate. Under these conditions,
with the pump completely stopped, the pressure of the
washing circuit can rise up to 6 barg (87 psig).
The pump must not run during this operation.
4.4 Pumps arranged in parallel
For applications where cleaning is easy and the differen-
tial pressure of, the SL Series pump is lower than 2 bar
(29 psi) during this operation, assembly in parallel is
authorised. It should be noted that during cleaning, the
SL Series pump will be acting on a product with generally
few lubricating properties. This will contribute towards
wear of the pump.
The CIP centrifuge pump must never be installed in
parallel with a SL Series pump without taking special
precautions.
Indeed, in this case, the pressure at the inlet of the
SL Series pump is lower than the pressure at the
discharge and the piston remains forced against the
cylinder. Therefore, there the SL Series pump no longer
provides a passage. Its efficient cleaning can no longer be
ensured and the cylinder/piston pair will become prematu-
rely worn.
Authorised assembly :
As mentioned previously for applications where cleaning
is easy, assembly in parallel is authorised when the
valves are installed so that the cleaning pressure of the
circuit does not come into contact with the SL Series pump.
In this case, the SL Series pump cleans itself.
Cleaning the pump :
We recommend limiting the rotation speed of the SL Series
pump.
Cleaning the installation :
The SL Series pump is stopped when cleaning the ins-
tallation.

4.5 Successive cycles
Generally, the most efficient CIPs comprise 5 stages :
1. Pre-washing with clean water
Water at room temperature. 10 to 15 minute cycle. This
pre-wash enables evacuation of the remaining residues.
2. Washing with an alkaline detergent
Typically this is soda at 2,5% at a temperature of 80°C.
20 to 30 minute cycle. This wash particularly enables
dissolving and evacuating grease and proteins.
3. Rinsing with clean water
Water at room temperature. 10 minute cycle. This rinse
enables avoiding the mixture of 2 cleaning solutions.
4. Washing with an acid solution
Typically this is nitric acid at 2,5% at room temperature.
10 to 15 minute cycle. This wash particularly enables
dissolving and evacuating proteins and inorganic salts.
5. Rinsing with clean water
Water at room temperature. Several 1 to 2 minute
cycles. These rinses enable evacuating all traces of
acid solution.
During all these CIP stages, the average speeds of the
cleaning liquids in the pipes must be between 1,5 and 3 m/s.
4.6 Sterilisation In Place (SIP)
The serie SL pumps are perfectly adapted to all pro-
cesses using SIP (Sterilisation In Place) : pump stopped
/ maximum 30 min per cycle / 1 or 2 cycles per day.

• With the help of a hub puller, extract the piston 301.
• Remove the cylinder 201 and the seals 113 and 306.
6.2 Checking of parts
The piston 301 and the cylinder 201 are active parts
(wearing parts).on which the pump's efficiency directly
depends. It is therefore advisable to regularly check the
pump's efficiency and replace the cylinder / piston if it
decreases.
In addition, as using a cylinder / piston that is too worn
may damage the pump's transmission system, it is advi-
sable to replace the cylinder / piston if the maximum
acceptable wear dimensions defined in the table below
are reached.
As changes in the pump's efficiency depend on the
conditions of use (pressure, rotation speed, liquid pum-
ped, etc.), MOUVEX recommends that users define the
monitoring ranges and the preventive maintenance
schedule according to their own experience.
When controlling the piston and even if it has not reached
its minimum dimensions, it may show following aspects,
especially on abrasive liquid pumping or low viscosity :
• Triangular shape on top of piston wall (A),
• Small steps at piston wall base (B).
Before putting back the piston on the pump, eliminate
these asperities by filing and finishing with fine sandpaper
(No 320 grain or equivalent), taking care of not scratching
any other surface around. Piston must then look as follows :
Do not retouch any other surface of the piston by
any mean as it can degrade pump performance and
reliability. In particular, do not round or attenuate
disc wall edges.
Even if it shows wearing signs, do not retouch any
surface of the cylinder by any mean as it can degrade
pump performance and reliability.

• Check the state of the seals 205, 305, 306,113 and
replace them if necessary.
• Position the seal 113 on the large flange and the seal 306
on the hub.
• Position the cylinder 201 such that the locating pin fits into
the notch of the back of the cylinder.
• Engage the piston 301 on the transmission hub 596, the gap
of the piston facing the cylinder partition.
• Give a small push to the piston to centre it and engage it in
the cylinder, then push it tight to the end while ensuring the
oblong hole of the piston is engaged on the 2 flats of the end
of the transmission hub 596.
• Place thread locking adhesive (Loctite®243* or equivalent)
on the thread of the transmission hub 596.
• Hold the piston 301 with a 70 Open-end spanner or a mon-
key wrench and screw-up the nut 304 after mounting the
seal 305 on to the rear face.
• Re-mount the front cover 405B and its seal 205.
•
Screw back the
6 screws 416 with their washers (8 x M16,
assembly torque 90 Nm).
It is important to keep a good grip on the piston,
its rotation could lead to deterioration of the bel-
lows. When tightening the nut, comply with the
assembly torque of 200 Nm.
