MARKET SECTORS
RESIDENTIAL.
APPLICATIONS
• Water circulation in heating and air
conditioning systems.
• Refurbishment or extension of existing systems.
• Recommended for facilities fitted with thermostatic valves.
• Single-family houses or apartment buildings.
• Floor heating systems.
SPECIFICATIONS
PUMP
•Flow rate: up to 3,2 m3/h.
•Head: up to 5,7 m.
•Maximum power consumption: 23 W (for the 4 m model)
and 42 W (for the 6 m model).
•Temperature of pumped liquid: -10°C ÷ +110°C.
Avoid condensation and ice formation.
Maximum 20% glycol and water mixture.
For glycol quantities higher than 20%, hydraulic performances
must be checked.
•Maximum operating pressure: 10 bar (PN 10).
•Rotor assembly group: made of stainless steel/composite material/carbon.
MOTOR
•Permanent magnet EC (Electronically Commutated) type motor with spherical
rotor/stator.
•Wet rotor with a single spherical ceramic/carbon bearing.
•Integrated motor protection; no external protection required.
•Single-phase 200-240 V 50/60 Hz power supply.
•Variable-speed motor, with automatic speed adjustment based
on system requirement.
•Insulation class F (155°C).
•Protection class IP 44.

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.

FURTHER PRODUCT SELECTION
AND DOCUMENTATION
XylectTM
XylectTM is pump solution selection software with an extensive online database of product information across the entire
Lowara, and Vogel range of pumps and related products, with multiple search options and helpful project management
facilities. The system holds up-to-date product information on thousands of products and accessories.
The possibility to search by applications and the detailed information output given makes it easy to make the optimal
selection without having detailed knowledge about the Lowara and Vogel products.
The search can be made by:
