High-efficiency circulators with screwed connection, EC motor and integrated electronic power control, designed for circulating liquids in heating, air conditioning and solar systems. With an energy efficiency index (EEI) at the ErP benchmark for most efficient circulators it contributes to energy savings.

The ideal choice for basic functionality needs.

Advantages

The pump also features six control modes – with total ten curves

LEDs indicate the actual operating status.
The pump has a ceramic shaft and radial bearings, carbon thrust bearing, stainless-steel rotor can, bearing plate and rotor cladding, composite impeller, all of which contribute to long life.
Best magnet material ensures the high efficiency of motor and pump. 
The pump is self-venting through the system, which contributes to easy commissioning. The compact design with integrated control box and control panel on side of the motor fits into most common installations.
The pump housing is made of cast iron and electro coated to improve the corrosion resistance.
The motor is a synchronous permanent-magnet/compact-stator motor characterized by high efficiency.
The pump speed is controlled by an integrated frequency converter incorporated in the control box.
The pump equipped with different fast connection solutions (fast connector, TE, Molex etc) to fulfill the requirements of different systems.
