3.1 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.
3.2 Direction of rotation
The pump is shown on the drawing (see § O
) direction of rotation anticlockwise. This pump
DIMENSIONS
is reversible. By reversing the direction of rotation, the
suction and discharge ports are also reversed. The
bypass, the pipe "K", the inlet and outlet have to be fitted
in the opposite direction of the drawing. The bypass cap
"E" must always be turned on the suction side.
To connect the pump draining device "H" to the outlet
thanks to a pipe welded on the discharge pipe.

3.3 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.
