1. Domestic heating and hot water supply systems

2. Air and ground source heat pump systems

3. Air-conditioning systems

4. Industrial hot water circulation systems

5. Solar thermal system 

High efficiency circulator pumps 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.

Easy installation and operation

Equipped with Self Adapting Mode(Auto Mode, Factory Setting), pump

runs once the power is connected and adapts its performance according

to actual system needs.

Low noise and high comfort

Noise index: ≤42dB(A)

Low energy consumption

A class energy efficiency, Power consumption lowest to 5W

Multiple protection

With over-voltage and over-current protection

Eco-Design Benchmark

EEI≤0.20-Part 2

Quick release power plug

Start-up and stop the pump quickly.

Product photo and control modes

Running lights

Switch between AUTO and Min-Max with button

 

Advantages

1. Intuitive one-button operation makes selection of any control mode simple

2. No external motor protection required reducing installation time

3. High-torque start improves startup under harsh conditions

4. Maintenance free and noiseless due to canned-rotor design and use of robust components

5. Fast connection plug makes electrical installation quick, safe and easy

6. Insulating shells  are available to minimize heat loss in heating systems

1. LEDs indicate the actual operating status.

2. 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.

3. 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.

4. The pump housing is made of cast iron and electro coated to improve the corrosion resistance.

5. The motor is a synchronous permanent-magnet/compact-stator motor characterized by high efficiency.

6. The pump speed is controlled by an integrated frequency converter incorporated in the control box.
