The operator should remain nearby the equipment through-
out the use to ensure the proper functioning of the system.
6.1 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.
6.2 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.
6.3 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.
6.4 Running without liquid in the pump
MOUVEX Submerged AM pumps can run without liquid
in the pump for 5 minutes without causing damage, in
particular during pump priming.
6.5 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.
6.6 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.
