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.
In the case of a very high intake or if you wish to prevent
the piping from emptying at shutdown, you can install a
foot valve. It should have a large diameter so as not to
generate additional head loss.
2.6 Direction of rotation
WARNING
FAILURE TO RELIEVE THE SYSTEM
PRESSURE PRIOR TO PERFORMING
ANY WORK ON THE PUMP OR THE
INSTALLATION CAN CAUSE PERSONAL
INJURY OR PROPERTY DAMAGE.
Hazardous pressure
can cause
personal injury
or property damage.
The MOUVEX pump is reversible, this allows it to always
circulate the liquid in the desired direction by choosing
the corresponding direction of rotation.
The intake and discharge connections are determined
as follows :
Clockwise rotation
2.7 Liquids containing a high proportion of
particles
In the case where the pumped fluid contains particles, it is
recommanded to choose a pump with connections oriented
horizontally (to specify when ordering) and to use the upper
flange as the inlet flange.
This facilitates discharge of the sediments formed by the
build-up of the particles contained in the fluid, so this
reduces friction between the hose and the shoes.
Therefore, the pump may be re-started more easily.

Anticlockwise rotation
2.8 Working with vaccum on the suction side
Because of the operating principle of the pump, using it
with suction pressure lower than the atmospheric pres-
sure will cause a resulting loss of flow more or less in
line with the conditions of the application (hose material,
rotation speed, temperature, etc.).
In order for the pump to generate the normally required
flow, MOUVEX recommends using a vacuum draw kit
inside the body of the pump.
In all cases, when using a vaccum kit, suction pressure
must not be lower than -0,9 barg (-13 psig).
If a vacuum draw kit is not used on an ABAQUE pump
operating with suction pressure lower than atmospheric
pressure, MOUVEX no longer guarantees the perfor-
mance of the pump.
2.9 Handling
The maximum weight of the pump is :
• A10 .................................33 kg (73 lb)
• AS10 ..............................15 kg (33 lb)
USE SUITABLE LIFTING DEVICES FOR
HANDLING.
USE THE LIFTING RINGS PROVIDED.
2.10 Pump location
Provide sufficient clearance around the pump for main-
tenance operations.
Particularly, make sure that there is sufficient clearance
for replacing the hose; the distance between the pump
flanges and the closest obstacle must allow the hose to
be removed, as shown below :
2.11 Anchoring the pump units
The correct seating of the pump is vital for its efficient
operation and its longevity.
The surface must be resistant enough to absorb the
stresses due to the pump unit without deformation.
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.
