L2 ELECTRICAL POWER SUPPLY
NOTE Depending on the model, the pump must be fed by three-
phase or single-phase alternating current whose nominal
values are those indicated in the Table of paragraph ELEC-
TRICAL SPECIFICATIONS.,
The maximum acceptable variations from the electrical
parameters are:
Voltage:+/- 5% of the nominal value
Frequency:+/- 5% of the nominal value
ATTENTION Power from lines with values outside the indicated lim-
its can damage the electrical components.
L3 WORKING CYCLE
NOTE The motors are intended for continuous use. Under nor-
mal operating conditions they can function continuously
with no limitations
For 240v voltage ratings (australia) the duty cycle is 30' on
/ 30' off.
ATTENTION Functioning under by-pass conditions is only allowed for
brief periods of time (2-3 minutes maximum).Whenever
a particular installation carries the risk of functioning in
by-pass mode for longer periods of time, it is necessary
that the by-passed flow not be recirculated inside the
pump, but be returned to the suction tank.

230 60 1150 5 1650 the other hand, if the system cannot be modified it will be necessary to select a pump
model with a higher Pmax.
SUCTION
VISCOMAT series pumps are characterized by excellent suction capacity. In fact, the
characteristic flow rate/back pressure curve remains unchanged even at high pump
suction pressure values. In the case of oils with viscosity not greater than 100 cSt the
suction pressure can reach values on the order of 0.7 - 0.8 bar without compromising
the proper functioning of the pump. Beyond these suction pressure values,cavitation
phenomena begin as evidenced by accentuated running noise that over time can
cause pump damage, not to mention a degradation of pump performance. As viscosity
increases, the suction pressure at which cavitation phenomena begin decreases. In the
case of oils with viscosities equal to approximately 500 cSt, the suction pressure must
not exceed values of the order of 0,3 -0,5 bar to avoid triggering cavitation phenomena.
The values indicated above refer to the suction of oil that is substantially free of air. If the
oil being pumped is mixed with air, the cavitation phenomena can begin at lower suc-
tion pressures. In any case, for as much as was said above, it is important to guarantee
low suction pressures (short hoses and possibly of larger diameter than the inlet open-
ing of the pump,fewer curves, filters of wide cross-section and kept clean).
ATTENTION It is a good system practice to immediately install vacu-
um and air pressure gauges at the inlets and outlets of
the pump which allow verification that operating condi-
tions are within anticipated limits. To avoid emptying
the suction hose when the pump is turned off, the instal-
lation of a foot valve is recommended.
