ASSEMBLY PROCESS
B e f o r e a s s e m b l i n g
(Only for pump ends)
Check that engine flange and shaft measures are in accordance with
diameter and threaded shaft.
All units are partially assembled. In the box there are bags with the
necessary screws and accessories to complete the assembly.
When opening the box be sure that the parts do not show evidence of
damage during transportation.
After unpacking the units, all the parts should be placed on a smooth, dry
and clean surface.
Read carefully all instructions given below before assembling the unit.
All models
Place the engine with the shaft vertically. Clean the matching surfaces, clean
the engine shaft and coat its surface with a small amount of grease.

INSTALLATION
The suction hose must be kept free
of air leaks, particularly when
the suction line is long and
the static suction is high.
It is advisable to keep the suction
hose as short as possible,
setting the pump as near
as possible to the liquid.
Use a pipe, or a reinforced hose to make suction connections. Hose must
have sufficient strength to resist collapsing under the atmospheric pressure.
The pump does not need a foot valve. Use a strainer to prevent solids from
being drawn into the pump and clog the pump impeller.
The strainer should be at least 1.5 times the suction diameter away from
the bottom of the container tank of the liquid pumped.
Align properly pipes and fittings.
Independently support pipes and fittings to reduce strain on the pump
casing.
Use Teflon tape on the joints to prevent leakage.
Suction area of the strainer must be at least four times the suction pipe
area.
Suction pipes hoses or fittings should have a diameter equal to the pump
suction diameter.
