*Value refers to pumps with 8.5 cm ³ / min capacities
5.1 Minimum level indicator
Electro-mechanical type
Normally closed at minimum level;
maximum commutable power ISA;
maximum commutable voltage 220/250 VAC.
Lubricant maximum level and reserve indicator is available on request: fitted with floats and two switches (minimum
and zero)
5.2 Pressure gauge (Accessory)
Two types of pressure gauge are available:
PART N°
299196
291395
5.3 Pressure regulator (Accessory)
Three types of regulator (valves) are available to protect the system from overpressures.
PART N°
299450
299451
299452
WARNING: Pay strict attention to what is indicated on the valves when assembling. Incorrect assembly of the
regulator (valve) can result in an overpressure which could prejudice the correct functioning of the pump itself and
be dangerous for the user.
