Gianneschi MVG - Temporary Storage

stator and rotor.
Important. Few revolutions in a wrong direction can damage the pump,
5.1
Preliminary actions before running the pump.
If the pump was stored with the oiled rotor before mounting the stator de-grease and clean
the rotor in order to avoid an incompatibility with the pumped fluid
-
Fill up the pump by water or the liquid that will be pumped. This operation has to be
carried out by using, for example, the draining plug
-
Connect correctly the pump to the both suction and delivery pipe-works
-
Close the port.
Note: The operation has to be done only at the first start. The following time the pump will
prime by itself.
-
Before connecting the power supply, check all valves, on the suction and delivery pipe-works,
are opened.
-
Start the pump for few seconds and verify that it is operating in the correct direction of
rotation as indicated by the directional arrows.
-
In a case of incorrect electrical wiring, contact a qualified electrician to reverse the power
supply connections.
-
Now, run the pump.
The pumps are volumetric type so they cannot work against closed valve, in order to avoid
damage on the rotating parts before the start open the valve and check the rotating
direction running briefly the motor.

Temporary storage.
Empty and clean the pump in case of:
-
Possible danger of freezing at the environment temperature for the pumped fluid especially
if the pump is installed in harsh clime.
-
Possibile fluid solidification
-
Possible incrustation on the joint.
Stator.
In case of long storage the rotor can alter the stator shape of the contact surfaces in a
permanent way. It needs a greater static torque at the first start.
We suggest to remove the stator and package and store it in an environment dust free, fresh
and ventilate protected by light.
Rotor.
Removed the stator, support the rotor on wooden support and cover it in order to avoid
damages, is case of long storage period grease the rotor.
