9.4 PERMITTED AND NON-PERMITTED FLUIDS

PERMITTED The unit can be used to transfer:
FLUDS - lubricant oil for motors, - lubricant oil for gearboxes, - diesel oil according to EN590.
NON
- lubricant oil for brakes, - windscreen liquid. - anti-freeze fluid
PERMITTED

It is important to remember that the performance of the unit depends on the following vari-
ables: - Temperature of the measured fluid; - Fluid type ; - System type

To guarantee the performance shown in the table, the system must be set up according
to the following characteristics:

The temperature limits shown apply to the pump components and must be respected
to avoid possible damage or malfunction. It is understood, nevertheless, that for a given
oil, the real functioning temperature range also depends on the variability of the viscos-
ity of the oil itself with the temperature. Specifically:
• The minimum temperature allowed (-10°C) could cause the viscosity of some oils to greatly
exceed the maximum allowed, with the consequence that the static torque required dur-
ing the starting of the pump would be excessive, risking overload and damage to the pump.
• The maximum temperature allowed (+40°C) could, on the other hand, cause the vis-
cosity of some oils to drop well below the minimum allowed, causing a degradation in
performance with obvious reductions in flow rate as the back pressure increases.
Depending on the model, the pump must be fed by single-phase alternating current whose
nominal values are those indicated in the Table of paragraph 8.1,
The maximum acceptable variations from the electrical parameters are:
Voltage:+/- 5% of the nominal value
Frequency:+/- 2% of the nominal value
Power from lines with values outside the indicated limits can damage the electrical com-
ponents.
The motors are intended for continuous use. Under normal operating conditions they can
function continuously with no limitations
