The pump E300 are self-priming and, therefore, able to draw oil from the tank
even when the suction hose is empty on start-up. The priming height (distance
between the surface of the oil and the inlet opening) must not exceed 2,5
meters.
- Check that the quantity of fluid in the suction tank is greater than the
amount you wish to transfer.
- Make sure that the piping and line accessories are in good condition.
- Do not run the pump dry. This can cause serious damage to its components.
- Do not operate switches with wet hands.
Fluid leaks can damage objects and injure persons.
- Never start or stop the pump by connecting or cutting out the power
supply.
- Prolonged contact with oil can damage the skin. The use of goggles and
gloves is recommended.
It is recommended to use a suitable preliminary filter and a suction kit
equipped with hose and foot valve (flow stop) to avoid long suction times
and a useless damage of the pump caused by solid foreign objects inci-
dentally sucked.
In the priming phase the pump must relieve the air initially present in the
entire installation out of the delivery line. Therefore keep the outlet open
to allow the air to be relieved.
If an automatic dispensing nozzle is installed at the end of the delivery
line, the air relief may be difficult because of the automatic stopping
device that keeps the valve closed when the line pressure is too low. It is
recommended that the automatic nozzle be temporarily removed during
initial start-up.
that the pump is not running completely"dry".
that the suction hose guarantees against air infiltration and is correctly im-
mersed in the fluid to be drawn.
that the delivery hose allows for the easy evacuation of the air.
that the pump is under head
That under conditions of maximum back pressure, the power absorption of
the motor stays within the values shown on the identification plate
That the suction pressure does not exceed the limits indicated in paragraph
CONSIDERATIONS REGARDING SUCTION & DELIVERY LINES
That the back pressure in the delivery line does not exceed the values indicated
in paragraph CONSIDERATIONS REGARDING SUCTION & DELIVERY LINES.
