4.1 Choice of 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.
4.2 Direction of rotation
The pump rotates in one direction only. This is indicated by
an arrow on the pump housing. However, the pump has
both of shaft-ends led out and must be driven through
one the other depending on the direction of rotation of the
power take-off.
Because the pump rotates in one direction only, the
positions of the suction and discharge ports are not be
reversed (see arrows on housing). The safety bypass
has not to be reversed.
4.3 Pump protection
It is essential to protect the pump against possible
foreign matter by connecting a filter to the suction pipe
(see Instructions 1011-G00 Filters PF).
4.4 Pipe diameter
In order to achieve the best usage conditions, it is impor-
tant to take the following recommendations into account
when it comes to pipe dimensions :
• The pipe diameter should be chosen as a function of
pipe length and the flow rate and viscosity of the pum-
ped liquid, so that any head loss remains within the per-
missible limits for the motor/pump unit. Therefore it is
difficult to give general and precise directions. However,
it is never a disadvantage to over-dimension pipe dia-
meters, especially for the section on the inlet side.
• In the case of thin liquids and the piping on the dischar-
ge side, one can generally allow a diameter equal to
that of the ports on the pump and a larger diameter for
the piping on the inlet side, if the value for the inlet
power of the pump is negative or especially high.
• In the case of viscous liquids, special care should be
given to choosing pipe diameters. In fact, the variation
in head loss is proportional to viscosity and inversely
proportional to the diameter as power of 3. A slight
reduction in the pipe diameter could have serious
consequences for the operating conditions of the pump.
Our Technical Services are always available to provide
you with precise data if you give them accurate informa-
tion or, better still, the installation plans.
4.5 Piping assembly
In order to achieve the best usage conditions, it is impor-
tant to take the following recommendations into account
when it comes to fitting pipes :
• The location of the pump in the transfer or recycling cir-
cuit should always be determined so as to reduce the
height and length of the piping as much as possible.
• Wherever possible, siphons and reverse slopes should
be avoided in the inlet piping.
• Particular care needs to be taken with the sealing on
the inlet side to prevent air entering.
• Pipe elbows must always have a large radius (more
than 3 times the diameter of the pipes) and must not be
mounted too close to the pump flanges (min. recom-
mended distance : 10 times the diameter of the pipes),
on both the inlet and discharge sides.
• The pipes are supported and aligned with the pump in
such a way as to avoid putting stress on the pump flan-
ges. Non-compliance with this instruction can lead to
deformation of pump parts, misalignment of bearings
and accelerated material wear, even causing parts to
break.
• For ease of adjustment and checking, it is recommen-
ded that pressure tapping ports for pressure
gauges/vacuum gauges be provided as close as pos-
sible to the pump’s inlet ports (preferably, at a distance
of less than 5 times the diameter of the piping).
• If the suction head is especially high or if you want to
prevent the pipes emptying at shutdown, you can
install a foot valve. It should have a large diameter so
as not to generate additional head loss.
• We recommend placing valves as close as possible to
the pump ports to avoid having to drain the entire sys-
tem each time maintenance is carried out. These val-
ves should have the same diameter as the pipes and
preferably by full bore models.
• All these steps should be taken to prevent foreign
bodies entering the pump (the use of a filter in the
pump inlet pipe is strongly recommended).
• Before installing new pipes or tanks, be sure to clean
them very carefully to remove any solder, rust, etc.
which could be carried along with the water and cause
excessive pump wear.
• The pipes should be designed to allow for thermal
expansion/contraction (the use of flexible hoses or
expansion loops is recommended).
• If the liquid may freeze or solidify, prepare for draining
the piping by installing drain taps at the low points and
air vents at the high points.
4. INSTALLATION

4.6 Bypass setting
The bypass must be set depending on the needs and
the limitations of the installation.
A preset can be operated for mechanical bypass, please
refer to the information below, but it has to be followed up
by a check-up on the installation.
Process :
• Loose the nut.
• Unscrew completely the pressure screw.
• Screw it clockwise depending on the values given below.
Please consider te accuracy is +/- 0,3 bar on the given
values.
• Tight the nut.
• Check on the installation the pump gives the right pres-
sure (using a manometer) with a closed valve on the
discharge line.

5.1 Installation of units
The correct seating of the pump is vital for its efficient ope-
ration and its longevity. The base must be flat, level and
sufficiently resistant to absorb the stresses caused by the
motor-driven pump without deformation (if it is made of
concrete, it must comply with standard BAEL 91).
In the case where the unit is fastened by anchor lugs or
bolts, it must be carefully wedged to prevent any defor-
mation of the chassis when tightening the bolts.
Deformation of the chassis will cause stress prejudicial
to the pump and the drive device and put the coupling
out of true alignment, thereby causing vibrations, noise
and premature wear. Care must be taken so that the
chassis is clear of the ground, apart from the base pla-
tes.
If the chassis is a one-piece unit in doubled plate, it is
recommended that a horizontal clearance of about 50
cm be left between one section of the chassis and the
other to allow access for fastening the nuts on the pump,
reduction gearbox and motor. In all cases, the clearance
around the motor-driven pump should all room for
demounting the pump (for distances, refer to the dimen-
sion drawing at the start of the notice).
The chassis is equipped with a ground connection that
must be used to protect people and equipment.
5.2 Alignment of motor/pump and reduction
gearbox/pump shafts
The motor and pump shafts are accurately aligned at the
factory before dispatch, but they should be checked
carefully when received at the site and realigned if
necessary. To align the coupling and the shaft, use a
straight-edge to check the concentricity and thickness
gauges for the angular misalignment.
The 3 figures below show the procedure in detail and the
admissible deviations :
Controlling the alignment at each stage of the installation
is important to be sure that none of the following procedu-
res has 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.
REMINDER :
You cannot rely on the coupling to compensate for mis-
alignment.
NEVER START A UNIT IF THE COUPLING ALIGNMENT IS
INCORRECT. THIS WILL RENDER OUR WARRANTY INVALID.

5. DIRECT DRIVE BY MOTOR

5.3 Electric motors
Check that the supply voltage matches the indications
on the motor rating plate.
Comply with the wiring diagram, make sure the wires are
rated for the power and take care with the contacts,
which must be thoroughly tightened. The motors must
be protected by appropriate circuit breakers and fuses.
Connect the regulatory ground connections.
Check the direction of rotation.
This check should be done with no liquid being pumped,
and both the inlet and discharge circuits vented to avoid
generating unexpected pressure (on the inlet side, for
example). This will avoid damaging either the pump or
the system.
Start the pump empty to check that the connections are
good and that the direction of rotation corresponds to the
system intake and discharge directions. 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.
5.4 Diesel engines drive
Do not forget that these engines are not reversible. It is
therefore vital to carefully check the inlet and outlet sides
of the pump before connecting the pump unit to the piping.
The use of diesel engines drive is now well known.
Nevertheless, we strongly recommend that you carefully
read the technical manuals concerning them.

7. USE
The operator should remain nearby the equipment through-
out the use to ensure the proper functioning of the system.
7.1 Pumping hot liquids
When pumping hot liquids, make your you retighten
screws and bolts after starting for the first time in order
to compensate for contraction.
7.2 Pump full of liquid when stopped
If the pump circuit is to be located between valves and/or
a non-return valve, you need to take account of the
variations in temperature that can lead to contraction of
the liquid in the circuit. In this case, you need to provide
some means of compensating for the contraction. A dis-
charge valve may be sufficient. The opening pressure
for this valve should be compatible with the permitted
pressure for the other components in the circuit.
It is also advisable to fit a discharge device to allow the
circuit to be completely emptied for any maintenance work.
In the case of liquids containing particles settling on
shut-down, it is necessary to make sure the consistency
of the deposit will not impede restarting the pump.
7.3 Starting-up the pump
Before starting the pump, make sure that the following
conditions are met :
• The circuit should be in one of its pumping configu-
rations, with the appropriate valves open, especially
on the intake side.
• For products requiring heating, they must be brought
to their pumping temperature before starting the
pump.
7.4 Running without liquid in the pump
MOUVEX CC8 pumps can run without liquid in the pump
for 5 minutes without causing damage, in particular during
pump priming.
7.5 Using of the pump with a valve closed on
the discharge line
The using of the pump with a valve closed on the dis-
charge line implies the liquid is not renewed which gene-
rates a heating up. In consequence, that operating way
must not exceed 3 minutes.
7.6 Shutting down the pump
When shutting down the pump, we recommend waiting
for it to stop completely before closing the valves, espe-
cially the inlet valve.

7.7 Protection from frost
If there is a risk of frost with the product contained in
the pump, it is necessary to drain the body after each
use as follows :
Step 1 :
• Check there is no valve closed on the discharge side
as well potential counter pressure due to a check
valve or liquid remaining inside a vertical pipe.
• Rotate the pump.
• Create an air entering on the suction side during 30
seconds.
• Stop the pump and make sure no liquid is coming
back > pump has to be closed.
Step 2 :
• Defect or in complement, drain by the bottom plug.
7.8 Restarting
Follow the standard start-up procedure for the pump/
motor-driven pump, as well as the instructions below.
Turn the pump by hand to make sure the parts move
freely.
Remove the bypass and inspect the parts and make
sure they move freely.

13. CHANGING MONOBLOC SHAFT SEAL
Dismantling
Set bypass at minimal pressure by unscrewing the
lock-nut 835 taking care to count the number of rota-
tions so as to be able to reset bypass at initial pressure
setting.
Unscrew the 3 screws 856 of the bypass cap 827.
Remove spring 824.
Remove the valve 823 by pulling its cylindrical section
with the fingers.
Check condition of bypass.
Reassembly
Clean all parts before reassembly.
Reassemble in reverse order of dismantling.
Set bypass at initial pressure setting by tightening nut
with the same number of rotations as counted during
dismounting.
14. BYPASS

15.1 Lubrication
• Grease to use : good quality ball bearing grease.
In case of pumps operated higher than 100°C, a high
point of drop grease has to be selected.
• Fréquency : every 500 hours or one time per year.
• Injected volume : the usage of a pneumatic grease pump
is forbidden because of the risk to damage the mecha-
nical seals. The grease has to be added with a manual
pump, 2 blows on an only one grease nipple of every
pump end.
15.2 Inspection of the vanes
15.3 Cleaning the filter
The pump should always be protected against possible
foreign matter by means of a filter connected into the
suction pipe.
Check the cleanliness of the filter mesh from time to time
as a.partly clogged filter could starve the pump and reduce
its output.
To clean the filter, remove the meshes and clean them
carefully. Before refitting them, drain the filter by removing
the drain plug, then rinse it thoroughly.

16. TROUBLESHOOTING
16.1 Abnormal noise
Main causes :
• Excessive suction vacuum, due to :
- a pipe, accessories (valves, filter...) which are either
clogged or of insufficient diameter,
- excessive suction head (e.g. during liquid transfer
operations),
- a viscosity or vapour tension too high for the system
to cope with (e.g. when changing the product to be
pumped).
• Overly high rotation speed for the liquid being pumped.
• Pump damaged
- as a result of binding due to :
• an excessively high rotation speed,
• failure to release the drive when pumping is ended,
• sudden engagement of the drive,
• an unduly high pulling force on the shaft, leading to
a damaged ball-bearing and shaft.
- as a result of foreign matter, due to :
• the absence of a filter or inefficient cleaning,
• the absence of a basket (faîlure to replace it after
cleaning),
• solder or rust particles remaining in the pipe bet-
ween the filter and the pump.
• Bypass valve hammer on its seat due to incorrect
adjustment of the spring’s tension.
16.2 Leaking seal
Main causes :
- Abnormal pulling force on the shaft, leading to a dama-
ged bearing and seal,
- Displacement of the shaft when mounting an unduly
tight coupling making the seal unserviceable,
- Seal damage caused by pumping an agressive product,
- Ball-bearing lubricated excessively or at unduly high
pressure.
16.3 Inadequate output
Main causes :
- Excessive suction vacuum (see § Abnormal noise -
Excessive suction vacuum),
- Bypass setting too low,
- Air leaking in at suction end,
- Discharge pipe diameter too small,
- Speed of rotation too low,
- Bypass valve not closing properly due to foreign mat-
ters on valve seat or because the valve lifting wheel (in
the case of pumps fitted with one) has not been retur-
ned to its initial position after use,
- Pump damaged (see § Abnormal noise - Pump damaged
due to passage of foreign matter).
CAUTION :
OBSERVE ALL SAFETY WARNINGS CONTAINED IN THIS MANUAL.

17.1 Short duration (≤ 1 month)
MOUVEX pumps and motor-driven pumps are well lubri-
cated when delivered to protect the internal parts during
brief storage in a building where :
• the temperature remains between 10°C and 50°C.
• the relative humidity does not exceed 60%.
• exposure to vibration is limited (maximum movement :
0,05 mm).
• pump is stored in an area sheltered from bad weather
and sun.
17.2 Long duration (> 1 month)
We recommend the following procedure for longer periods
of storage :
The recommendations from the manufacturer should be
followed if the pump is stored with its gear motor.
Pump ports should be filled with a non-corrosive liquid
that it compatible with the pump components in order to
prevent corrosion.
Unpainted external surfaces of the pump (e.g. shafts,
couplings, etc.) should be covered in some form of anti-
corrosion protection.
The bearing should be greased. If the pump is to be stored
for more than three years, the grease should be replaced
every three years to prevent it degrading.
The best storage conditions are inside a building that
meets the conditions set out above.
If inside storage is not possible, the materials should be
covered to prevent direct exposure to sun and bad wea-
ther. This protection should also prevent condensation.
It is recommended to turn the pump by hand every two
months to distribute the lubricant around the interior.
Items should then be placed where there is no risk of
damage if they are moved slightly by vibrations.
WARNING
IF PUMPING HAZARDOUS OR TOXIC
FLUIDS, THE SYSTEM MUST BE FLUS-
HED PRIOR TO PERFORMING ANY
SERVICE OPERATION.
Toxic or hazardous
fluids can cause
serious injury.
17. STORAGE
The pump must be scrapped in compliance with the regulations
in force.
During this operation, particular care must be paid to the drai-
nage stages of the pump (pumped product).
