Pumps of stainless steel
The nylon fittings supplied on request are made up of three components; use PTFE tape for hydraulic purposes to ensure the tight-
ness between the pump hose and the nipple; the tightness between the nipple and the remaining part of the fitting is obtained through
taper fit, without gaskets.
6) Insert the end of the pipes into the fittings; the inner diameter of the pipes must be the same of the outer diameter of the fittings;
secure the connection with hose clamps; the suction pipe must be anti-crushing; the delivery pipe must be able to bear the maxi-
mum pressure produced by the pump (see Tab. A and chapter 2.1); as the pump is self-priming, the installation of a nonreturn valve
is not necessary; put the free end of the suction pipe into the tank from which you want to suck the liquid and the free end of the
delivery pipe into the tank where you want to send the liquid.
CAUTION:
When operating, the delivery pipe, owing to the fluid pressure, may withdraw from the tank and squirt the sur-
rounding area; it is therefore advisable to fix the pipe (in particular in the case of harmful or combustible liquids, such as
gas oil).
7) Electrical connections
CAUTION:
standard EN 60204 - 1 - 2. Ed.
- Check that cables and sockets for connection have no damages before use.
- Be sure that the electric connections are in a place sheltered from inundations and, anyway, protected from humidity
In the standard version the electric motor is supplied without any thermic protection built-in; if needed, the protection
should be provided by the user.
Types with AC single-phase or three-phase motor
- Check that the switch is in the position "0" (OFF).
- Connect the motor cable to a socket after checking that voltage and frequency coincide with those written in the motor plate; a tole-
rance of 10% is admitted for voltage, of 2% for frequency;
C A U T I O N
- The electric pump must absolutely be connected to a socket connected to the ground and protected by a 30 mA
d i ff e rential safety switch.
- If you need to install a patch cord, choose the wire section according to the current, written in the motor plate
(refer to the electrical standards in force)
- The switchreverser contains electrical parts; only expert and qualified personnel can disassemble it, observing
the safety rules.
- In the models supplied without plug the connection to the power grid must be carried out by expert personnel
- In the models supplied with terminal board on request the connection to the power grid must be carried out by
expert personnel following the instructions inside the terminal board cover.
Types with DC motor
CAUTION
When connecting types with DC motor to the power supply, it is compulsory to comply with the polarity
(+, -) shown in the terminal board
- Unscrew the terminal board cover.
- According to the current absorbed by the motor (see plate) choose a couple of electric cables with a proper section.
- Insert the cables through the whipping.
- Connect them to the terminal board.
- Screw the terminal board cover.
- Insert a switch in the circuit, if not present in the power supply, to make the pump run and stop easy; make sure it is in OFF posi-
tion.
- Connect the cables to a D.C. generator; its voltage must correspond to that written in the plate (tolerance 10%).
8) Start the pump by commuting the switch to one "ON" position; after a few seconds, necessary for the priming, the pump begins
to transfer liquid;
CAUTION:
If the pipes have not been correctly connected, there may be liquid leaks or jets
Check if the suction pipe gurgles air into the liquid to be sucked; in this case the pump is pumping in the opposite direction; then
commute the switch reverser to the other "ON" position or (types with DC motor) invert the connection of the fittings to the pump
h o s e s .
9) Stopping the pump: set the switch to position "0" (OFF) or disconnect the cable from the power supply; for a further start it is not
necessary to refill the pump body with liquid.
The pump, when switched off, remains full of liquid; in case the outside temperature may fall below the liquid freezing point, empty
the pump after use to avoid the break of the pump body.

IMPORTANT

a) the pump must not be set in motion before completing its installation.
b) You must not insert fingers or other parts of the body through the hoses; the pump contains parts
in motion.
IThe electrical connections must be carried out in accordance with the prescriptions of the
