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 determined in accordance with the pumped liquid and the installation 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 diameters, 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 inversely 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 recommendations 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 shouldbe 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. recommended 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 deformation of pump parts, misalignment of bearings and
accelerated material wear, even causing parts to break.
• For ease of any adjustments and checks, it is recommended that pressure tapping ports to which pressure/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 preferably 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 expansion/contraction (the use of flexible couplings or expansion 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.

NT 1007-A00 11.11 SLP25 i series pumps e
2.4 Direction of rotation
• In its standard configuration, the SLP series MOUVEX
pump is supplied as non reversible and with anticlockwise 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 rotation 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 overpressure
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 internal relief valve to protect the system in one operating
direction. Its orientation therefore depends on the operating 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 directions, (whatever the operating conditions), it is recommended 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 appropriate liquid or by dismantling the pump and carefully cleaning 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 chassis could cause prejudicial stress to the pump and the
drive device and put the coupling out of alignment, causing 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 § OVERALL 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 automatically 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 temperature.
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.
