1. Domestic heating and water supply system

2. Air and ground source heat pump system

3. Air-conditioning system

4. Industrial hot water system

5. Solar thermal system

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

7.       The pump features three constant-curve modes, proportional pressure curves, constant pressure curves, auto and night mode.

8.        In terms of electricity consumption, the unique operation mode makes high efficiency circulator pumps more energy saving.

9.       High efficiency circulator which features well-designed compact structure, integrated controller and frequency converter.

10.   It is easy for installation and operation in most fields of applications.

 

 

Easy installation and operation

Equipped with Self Adapting Model (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.

Media requirements

Medium: water or water + glycol (≤ 50%) mixture

Medium temperature : 2℃~110℃

PH value of medium 6.5-8.5

Medium hardness 25°dH

Content of solid impurities in medium: diameter and length direction of solid impurities ≤ 0.1mm, and volume ratio ≤ 0.1%.

 

Service environment requirements

Usage: keep the shaft horizontal

Altitude: < 1000m

Operating ambient temperature: 0 ℃ ∼ 70 ℃

(there is no freezing in the pipeline and water pump)

Operating ambient humidity≤95%

 

 

Storage environment requirements

Storage ambient temperature: - 30 ℃ ∼ 70 ℃

(there is no freezing in the pipeline and water pump)

Humidity of storage environment: ≤95%

 

Start and stop of pump

Starting time: the starting time of the water pump is less than 3S, that is, the time from power on to reaching the maximum speed

Shutdown time: the shutdown time of the water pump is less than 1s,that is, the time from power failure to shutdown of the water pump
