2.5.4 THERMIC MOTORS
Do not forget that these motors are not reversible. It is
absolutely necessary to carefully control the suction and
discharge sides of the pump before connecting the
group to the piping.
Using electric motors is very common now; however, we
strongly advise careful reading of the accompanying ins-
truction manual.
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 pressu-
re (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 noti-
ce supplied with the motor.
A DRIVE SHAFT GUARD BETWEEN THE
PTO AND PUMP MUST BE PROVIDED TO
PREVENT PERSONAL INJURY, PROPERTY
DAMAGE, OR DEATH.
WARNING
Do not operate
without guard
in place.
IT IS IMPERATIVE THAT THE HYDRAULIC
PRESSURE IS RELEASED BEFORE EACH
MAINTENANCE OPERATION TO AVOID
PERSONAL INJURY OR MATERIAL
DAMAGE
WARNING
Hazardous pressure
can cause
personal injury
or property damage.
TAKE ALL NECESSARY MEASURES TO
RENDER ANY START-UP, EVEN ACCIDEN-
TAL, OF THE PUMP DURING THE WORK
IMPOSSIBLE.
WARNING
Any unforeseen start-up
can cause serious
injuries or important
material damages.
THE SURFACES CAN BE AT A TEMPERA-
TURE LIABLE TO CAUSE INJURY OR
SEVERE DAMAGE.
CAUTION
Excessive temperature-
can cause injury or
severe damage.

6/12
3.1 Commissioning
Before starting-up the pump, rinse the whole installation
so as to eliminate any contaminants that may remain in
the pipes, tanks etc. at the time of installation,
taking
care to bypass the pump.
3.2 Dry running
The pump may run dry for a maximum duration of 5
minutes.
At priming :
From a practical point of view, the time necessary for pri-
ming is much lower than this value.
If, after a period of 1 min., the product is still not in the-
body of the pump, we recommend reconsidering the ins-
tallation at the suction section.
Draining of pipes (suction & discharge) :
A compressor effect close to 3 bar is obtained for a per-
iod of 3 minutes. After that, the value falls to 0.5 bar as
the lubrication ensured by the pumped product rapidly
disappears from between the piston and the cylinder.
3.3 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 (lubricant).
For any pure water pumping during process or
cleaning operations, consult Mouvex imperatively.
