CONSTRUCTION
CHARACTERISTICS

• Improved hydraulics to improved efficiency.

The cast iron pump housing is cataphoresis coated completely and is therefore
resistant to corrosion.

• The spherical rotor. The permanent magnet rotor/impeller unit is the only

moving part. Spherical motor pumps are shaftless, and therefore whisper quiet
over the whole lifetime. In case of an indicated rotor blocking, emergency
software shakes and vibrates the rotor to avoid further blocking.

• Anti-Block-Technology allows to separate the magnetic chamber from the

flow, preventing magnetite and sludge to block and damage the pump.
Blocking up, even in very old, open systems is impossible by our pump design.

• Three in one control:

- step-less manually control constant speed, (displayed by a white LED),

- automatic differential pressure, (displayed by a blue LED),

- automatic constant pressure, (displayed by a green LED).

• Digital multi-Display that shows automatically and alternatively power

consumption (Watt), head (m), and flow-rate (m3/h). The display provides also
detailed information on the air purge mode status as well as detailed error
messages.

• Optimized motor technology: Doubled electric windings combined with

the latest 32 Bit processor technology - that also makes the ecocirc even more
efficient.

• Overtemperature protection feature that slows down the circulator in

case the temperature of the electronic module is too high and shuts it down
when temperature rises above the safety limit. The circulator will automatically
restart after having cooled down.

• Always easy to access: The screw ring design results in a pump motor that

can be rotated in any position around the 360°circle. The electrical connection
as well as the control knob is therefore easy to access.

• Plug an easy and quick electrical connection. By turning the stator via the screw

ring the plug can be fixed in any position, making the installation even in the
hardest and tightest environment easy.

• Automatic air purge: Quick automatic air-venting-mode for a safe operation.

• According to EN standards 60335-1, 60335-2-51, 55014-1, 55014-2,

16297-1, 16297-2.

CONTROL MODES

• Automatic regulation: the pump automatically adjusts the working conditions

based on the requirement of the system. When the pump detects a decrease
in the flow, the inverter reduces the differential pressure of the pump until it
reaches the required head.

ACCESSORIES

• Pipe unions.

• Insulation shell.

INSTALLATION

• Suitable for installation in vertical or horizontal piping, in this last case

not with the motor housing upward.
