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
|
Intuitive one-button operation makes selection of any control mode simple
No external motor protection required reducing installation time
High-torque start improves startup under harsh conditions
Maintenance free and noiseless due to canned-rotor design and use of robust components
Fast connection plug makes electrical installation quick, safe and easy
Insulating shells are available to minimize heat loss in heating systems

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.
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.
