heat pumps, solar systems, air conditioning systems, closed cooling
circuits and industrial circulation systems.
For technical reasons, the contact surface between the rotor and the
ceramic ball bearing in spherical motor pumps is very small. For this
reason, even if they have not been in operation for a long time, such as
after the summer, only a small amount of torque is required to start the

The ecocirc pump can have three standard and two auxiliary
operation modes:
Constant Speed
Proportional Pressure
Constant Pressure
NOTE: Constant Pressure mode is only available in PREMIUM configuration
Automatic Air Purge
Standby
Instructions to change between operation modes:
- To change between standard operation modes (proportional pressure
constant speed and constant pressure) the user shall turn the knob
until the low end position and turn the knob back to the desired setting
within 5 sec. Pump indicates mode change by switching the color of
the knob LED (proportional pressure is blue, constant speed is white,
pumps do not require (and thus do not have) a

The user can set the speed of the pump
by turning the knob into any position
between 1 and 7, 7 is the fastest. The
preset speed remains constant,
independently from the flow.
The user can set the maximum strength
of the pump by turning the knob into any
position between 1 and 7, 7 is the
strongest. The pump automatically
decreases its speed at low flow, thus
providing energy saving.
The user can set the elevation height
(pressure) of the pump by turning the
knob into any position between 1 and 7,
7 being the highest pressure. The preset
pressure remains constant
independently from the flow.
The user can purge the trapped air from
the pumphouse.
The user can keep the power
consumption low (<1W) when pump
operation is not needed.
