2.1 Pump selection
To obtain expected performance from MOUVEX series
SLP pump, regarding both performance and durability, it
is essential that the type of pump, its rotation speed and
the materials used in its construction are suitably deter-
mined in accordance with the pumped liquid and the ins-
tallation and operating conditions.
OOur technical departments are at your disposal any
time for all necessary informations.
2.2 Pipe diameter
To obtain optimum conditions of use, it is important to check
the following recommendations regarding the sizing of
pipes :
• The pipe diameter will be determined depending on
their length and the flow and viscosity of liquid pumped,
so that pressure losses stay within the admissible limits
for the motor-driven pump unit. It is therefore difficult to
give general and precise instructions. However, it is
never a disadvantage to over-dimension pipe diame-
ters, especially for the section on the inlet side.
• In the case of thin liquids and the piping on the discharge
side,one can generally allow a diameter equal to the
pump ports 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.
• For viscous liquids, special attention should be paid to
determining the pipe diameters. Indeed, the variation in
pressure loss is proportional to the viscosity and inver-
sely proportional to the diameter exponent 4. A slight
reduction in the pipe diameter could therefore have
serious consequences on the pump’s operating conditions.
Our Technical Services are always available to provide you
with precise data if you give them accurate information
or, even better, the installation drawings.
2.3 Piping assembly
In order to achieve the best operating conditions, it is
important to take account of the following recommenda-
tions regarding piping assembly :
• The positioning of the pump in the transfer or recycling
circuit should always be chosen 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 pipe diameter), on both
the inlet and discharge sides.
• The pipes are supported and aligned with the pump so
as to avoid generating stress on the pump flanges.
Non-compliance with this instruction can lead to defor-
mation of pump parts, misalignment of bearings and
accelerated material wear, even causing parts to break.
• For ease of any adjustments and checks, it is recom-
mended that pressure tapping ports to which pressu-
re/vacuum gauges may be fitted, are provided as close
as possible to the pump’s suction and discharge ports
(preferably at a distance of less than 5 times the pipe
diameter).
• If the suction head is especially high or if you want to
prevent the pipes emptying at shutdown, you can install
a foot valve. This should have a large diameter so as
not to generate additional pressure loss.
• We recommend placing valves as close as possible to
the pump ports to avoid having to drain the entire system
each time maintenance is carried out. These valves
should have the same diameter as the pipes and pre-
ferably be full bore models.
• All steps should be taken to prevent foreign bodies
from entering the pump (the use of a filter at the pump
intake is therefore strongly recommended).
• Before installing new pipes or tanks, check that they
are carefully cleaned to remove waste from welding,
rust, etc. which when carried through by the liquid
could cause deterioration to the pump.
• The pipes should be designed to allow thermal expan-
sion/contraction (the use of flexible couplings or expan-
sion loops is therefore recommended).
• If there is danger of the liquid freezing or solidifying, it
must be possible to drain the piping by installing taps
at the low points and air vents at the high points.

2.4 Direction of rotation
• In its standard configuration, the SLP series MOUVEX
pump is supplied as non reversible and with anticlock-
wise rotation.
NOTE :
ALL VIEWS IN THIS INSTRUCTION MANUALSHOW PARTS IN
THE STANDARD DIRECTION OF ROTATION.
The rule for the discharge side and the direction of rota-
tion is as follows :
• For anticlockwise rotation (standard), the discharge
should be on the right side of the pump.
• For clockwise rotation, the discharge should be on the
left side of the pump.
In all cases, suction is from the top.
Operation in the opposite direction from that designed
for the pump is authorised nonetheless for a maximum
duration of 5 minutes as long as it remains below the
pressure limits (1,5 bar at the bellows).
The direction of rotation may be reversed :
• On request at the time the order is placed. In this case
the pump will be supplied with clockwise rotation.
• Or manually, referring to the following §.
2.5 Changing the direction of rotation
REGARDLESS OF THE INTERNAL DESIGN OF THE PUMP, THE
DIRECTION OF ROTATION SHOULD NOT BE CHANGED UNTIL
THE PUMP HAS COME TO A COMPLETE STOP, HAS COOLED
DOWN AND HAS BEEN DRAINED.
• Dismantle the connection manifold (see § DISMANTLING
/ASSEMBLING THE CONNECTION MANIFOLD).
• Dismantle the relief valve (see § ORIENTATION OF
BYPASS).
• Change the position of the rotor, the vanes and the
pushrods (for a pump with pushrods) : see § OPENING
AND CLOSING THE PUMP ON THE NON-DRIVE SIDE.
• Remove the vanes 44317 and the pushrods 44318.
• This may be carried out by removing the vanes 44317
horizontally and then the pushrods 44318 using a
screwdriver and pushing them to one of the pump outlet
ports.
• Follow the same procedure for the other vanes 44317.
• Remove the circlips 11119 (BE CAREFUL not to
scratch the shaft).
• Remove the rotor 44301, turn it over and re-assemble
it so that the rotor pushrods 44301 match up with the
holes in the shaft 44501.
• Place a suitable screw at the end of the shaft to pull it
and reveal the circlip groove.
• Replace the circlips 11119 taking care not to scratch the
shaft 44501.
• Re-assemble the vanes 44317 and the pushrods 44318
facing the correct direction (see § VANE CHECKS).
• Re-assemble the bypass facing the correct direction
(see § DIRECTION OF BYPASS).
• Re-assemble the connection manifold on the correct
side (see § DIRECTION OF ROTATION).

2.6 Protecting the installation against over-
pressure
To protect the installation from any overpressure, the
use of a pressure relief safety device is recommended.
The standard pump is supplied fitted with a single inter-
nal relief valve to protect the system in one operating
direction. Its orientation therefore depends on the opera-
ting direction of the pump (refer to § RELIEF VALVE).
It is also possible to order the following option :
• Without relief valve : the pump then has no other inbuilt
safety device. In this case, the pump must be protected
(for example with a pressure switch) to reduce any
overpressure.
If the rotation of the pump is to be used in both direc-
tions, (whatever the operating conditions), it is recom-
mended to use a device that protects the pump from
overpressure when rotating in both directions (pressure
switch, etc.).
2.7 Cleaning
As the pumps are well-greased when supplied, it may be
necessary to clean them before starting them up.
They may be cleaned either by circulating an appropria-
te liquid or by dismantling the pump and carefully clea-
ning the internal parts (in which case, refer to § relating
to pump maintenance).
2.8 Hoisting devices
Hoisting points :
The strap must pass between the cradle and the
manifold.
• Use straps designed for the weight of the pump (see
overall dimension drawing).

2. INSTALLATION (continued)
2.9 Installation of units
The correct seating of a unit is essential for ensuring
smooth operation and longevity. The base must be flat,
level and sufficiently resistant to absorb stresses caused
by the motor-driven pump without being distorted
(concrete blocks must conform to the BAEL 91 standard).
Where the unit is fastened using anchor lugs or bolts, it
must be wedged carefully to prevent any distortion of the
chassis when tightening the bolts. Distortion of the chas-
sis could cause prejudicial stress to the pump and the
drive device and put the coupling out of alignment, cau-
sing vibrations, noise and premature wear. Check that
the chassis is clear of the floor and off the support
plates.
Where the chassis is a one-piece unit in folded sheet
metal, it is recommended to leave a clear horizontal
space of around 50 cm between one end of the chassis
and the other to allow access to the locking nuts on the
pump, the reduction gearbox and the motor. In all cases,
the space around the pump unit should allow enough
room for dismantling the pump (refer to the overall
dimension drawing at the beginning for details of these
distances).
The chassis is equipped with an earth connection that
must be used to protect personnel and equipment.
The mounting base of the vane pump body and the
pump bearing are not on the same level (see § OVE-
RALL DIMENSIONS). Different wedging must therefore
be used for these two bases.
2.10 Alignment of motor/pump or reduction
gearbox/pump shafts
The motor and pump shafts are accurately aligned in the
factory before dispatch, but they must be checked auto-
matically upon arrival and realigned if necessary. To align
the coupling and the shaft, use a straight edge to check
the offset and thickness gauges for angular misalignment.
The 3 figures below illustrate the operation and show the
admissible deviations :
It is important to check the alignment at each stage of
installation to ensure that no stresses are caused to the
unit or the pump :
• after fixing to the base.
• after attaching piping.
• after pump has operated at normal operating tempera-
ture.
Reminder :
The coupling must not be relied on to compensate for a
misalignment.
NEVER START A UNIT IF THE COUPLING ALIGNMENT IS
INCORRECT. THIS WILL INVALIDATE OUR WARRANTY.

2.11 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 check the contacts which must
be thoroughly tightened. The motors must be protected
by appropriate circuit breakers and fuses. Connect the
regulatory ground connections.
Rotation direction check :
This check should be carried out on the pump with no
liquid being pumped through and both the suction and
discharge circuits venting so as to avoid generating
unexpected pressure (at suction for example). This will
avoid damaging either the pump or the system.
Start the pump empty to check that the connections are
sound and that the direction of rotation corresponds to
the system intake and discharge directions. If it should
be required 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.
2.12 Diesel engines drive
Do not forget that these engines are not reversible. It is
therefore essential to check carefully the pump’s intake
and discharge sides before connecting the unit to the
pipes.
The use of diesel engines drive is now well known.
However, we strongly advise careful reading of the
accompanying technical manual.

3. USE
3.1 Pumping hot or cold liquids
For hot liquids : after the initial start-up, make sure that
the screws and bolts are tightened to compensate for
the effects of expansion.
3.2 Pump full of liquid when stopped
Where the pump circuit is to be positioned between
valves and / or check valves, account must be taken of
the temperature variations that may occur and lead in
particular to expansion of the liquid in the circuit. In this
case, a means must be provided of discharging the
expanded volume. The use of a relief valve may fulfil this
function. The opening pressure of this valve should be
compatible with the admissible pressure for the various
components of the circuit.
It is also advisable to fit a discharge device enabling the
circuit to be completely emptied for any maintenance work.
Where liquids contain particles that may settle on shut-
down, it is necessary to ensure that the consistency of
the deposit will not prevent the pump being restarted.
3.3 Noise level
The noise level of a pump is generally influenced by the
conditions of use. Cavitation and the pumping of pro-
ducts with high gas content generally increase the noise
level.
Under the following pumping conditions :
• excluding cavitation
• maximum differential pressure : 12 bar
• rotation speed 1000 rpm
• product viscosity of 1 cSt
The noise level expected for an SLP series pump in good
operating condition without the drive is less than :
• SLP25 i . . . . 74 dB(A)
3.4 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
those on the suction side.
• For liquids requiring heating, they must be brought to
their pumping temperature before starting the pump.
3.5 Shutting down the pump
When shutting down the pump, it is recommended to
wait for it to stop completely before closing the valves,
especially the suction valve.

3. USE (continued)
3.6 Storage
MOUVEX pumps and motor-driven pump units are well
lubricated when delivered to protect the internal parts
during brief storage in a building where :
• the temperature must remain between 10°C and 49°C.
• the relative humidity does not exceed 60%.
• exposure to vibration is limited (maximum movement :
0,05 mm).
We recommend the following procedure for longer periods
of storage :
3.6.1 Storage
If the pump is stored with its gear motor unit, the recom-
mendations of the manufacturer for this equipment should
be followed.
Pump ports should be filled with a non-corrosive liquid
that is 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 best storage conditions are inside a building that
meets the conditions described above.
If inside storage is not possible, the equipment should
be covered to prevent direct exposure to sun and rain.
This protection should also protect the equipment from
any 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
components being damaged if they are moved slightly
by vibrations.
3.6.2 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.
If the pump has a safety internal relief valve, remove it and
inspect the parts and make sure they move freely (see §
RELIEF VALVE FOR DISMANTLING INSTRUCTIONS).
For the transmission unit, the bearing must be drained
(see § DRAINING OF BEARING).
3.7 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).
IF PUMPING HAZARDOUS OR TOXIC
FLUIDS, THE SYSTEM MUST BE FLUSHED
PRIOR TO PERFORMING ANY SERVICE
OPERATION.
WARNING
Toxic or hazardous
fluids can cause
serious injury.
