13.2 PIPING CONNECTIONS
FOREWORD
- Before carrying out any connection, refer to the visual indications i.e. arrow on the pump head,
to identify suction and delivery.
ATTENTION
PRELIMINARY
- Before connection, make sure that the piping and the suction tank are free of dirt and solid
residue that could damage the pump and its accessories.
INSPECTION
- Before connecting the delivery pipe, partially fill the pump body, from delivery side, with the
liquid that needs to be pumped in order to facilitate priming.
- Do not use conical threaded fittings, which could damage the threaded inlet or outlet openings
of the pump if excessively tightened.

Wrong connection can cause serious pump damage.
If not already fitted, fit a suction filter
- Check that the quantity of fluid in the suction tank is greater than the amount you
wish to transfer.
- Make sure that the residual capacity of the delivery tank is greater than the quantity
you wish to transfer.
- Make sure that the piping and line accessories are in good condition.
Do not run the pump dry for more than 20 minutes. This can cause serious
damage to its components.
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 some fluids can damage the skin. The use of goggles and
gloves is recommended.
Extreme operating conditions with duty cycles longer than 20 minutes
can cause the motor temperature to rise thus damaging the engine. For
each duty cycle of 20 minutes, allow for a rest phase of 20 minutes with
motor switched off.
During the priming phase, the pump must discharge all the air that is ini-
tially present from the delivery line. Therefore it is necessary to keep the
outlet open to permit the evacuation of the air.
If an automatic type dispensing nozzle is installed on the end of the deliv-
ery line, the evacuation of the air will be difficult because of the automatic
stopping device that keeps the valve closed. It is recommended that the au-
tomatic nozzle be temporarily removed during initial start-up.
