2.5.5 CONTROL OF THE SENSE OF ROTATION
This control needs to be done with no liquid pumped
through the pump, and both the suction and discharge
circuits venting to avoid generating unexpected pressure
(at the suction side, for example). This will ensure that
the control will not damage either the pump or the instal-
lation.
Start the pump empty to check that the connections are
good and that the direction of rotation corresponds to the
suction and discharge direction on the installation. If it is
necessary 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.
WARNING
TAKE ALL NECESSARY MEASURES TO
RENDER ANY START-UP, EVEN ACCI-
DENTAL, OF THE PUMP DURING THE
WORK IMPOSSIBLE.
Any unforeseen start-
up
can cause serious
injuries or important
WARNING
IT IS IMPERATIVE THAT THE HYDRAU-
LIC PRESSURE IS RELEASED BEFORE
EACH MAINTENANCE OPERATION
TO AVOID PERSONAL INJURY OR
MATERIAL DAMAGE
Hazardous pressure
can cause
personal injury
or property damage.
WARNING
IF OPERATED WITHOUT THE SHAFT
GUARD, THERE IS CONSIDERABLE RISK
OF SEVERE PERSONAL INJURY, SIGNIFI-
CANT PROPERTY DAMAGE OR EVEN
DEATH.
Do not operate
without guard
in place.

3. USE
3.1 Noise level
The sound level of a pump is greatly influenced by its
conditions of use. Cavitation and pumping products with
high gas contents generally increases the sound level.
Under the following pumping conditions :
• excluding cavitation
• discharge pressure :
• speed of rotation 1000 rpm
• product viscosity of 1 cSt
The sound level reached for a MICRO C pump in good
working condition without the drive is lower than 77 dB(A).
3.2 Commissioning
Make sure that the circuit valves are open before start-
ing the pump.
To avoid any risk of polluting the pumped product, rinse
the whole installation before starting-up so as to elimi-
nate any contaminants that may remain in the piping,
tanks etc. at the time of assembly.
3.3 Dry running
The Micro C pump is self priming and is able to empty
the pipes. To do this, it can run dry for a maximum
duration of 5 minutes.
For ATEX, see Instructions 1071.
3.4 Stopping the pump
So as not to damage the pump, make sure that the
pump is completely stopped before closing the valves.
3.5 Bellows monitoring
Failure of the bellows manifests itself as a liquid leakage
at the vent (see overall dimensions drawing), when the
suction is in positive pressure (>1 relative bar =14,5 psi).
The vent must remain in the open air at atmospheric
pressure (life time of the bellows will be reduced if the
vent is closed).
3.6 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 (grease).
For any pure water pumping during process or
cleaning operations, consult Mouvex imperatively.
