Energy Saving

Clean liquids, not aggressive and not explosive, not containing solid particles, fibers
or mineral oils.
for the use with other fluids, aSKoll’s authorization is required.
2.2 technical features
The pumps are not to be used to transfer flammable liquids such as
gasoline, oils, gas oil or similar liquids.
The pump must never be used for the circulation of domestic water or
in the foodstuffs field.

2.3 Description of the pump
Wet rotor circulation pump with integrated frequency commutator (INVERTER).
No mechanical seal is required. No protection against overload is required. The
motor is protected against short-circuit operation.
The motor is integrated with an electronic module allowing the adjustment of the
head/pressure difference from 1.7 m to 5.7 m (with Q = 0 m 3 /h).
Adjustment elements located on the terminal board box:
– Trimmer to adjust the rotation speed value set at output.
– Warning light (LED) of commissioning / fault signaling.
