Item NO.:
Master SD 25-51. 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. The speed can also be controlled by a low-voltage PWM signal from a controller to optimize the system performance, both PWM1 for heating and PWM2 for solar systems are available.
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.
11. In terms of electricity consumption, the unique operation mode makes high efficiency circulator pumps more energy saving.
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. Control is affected by digital pulse-width modulation (PWM) low-voltage signal, enabling the pump to be used to meet different flow requirement in various systems.
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
In PWM mode, when starting from the stop state of the water pump (without power supply), 90% of the maximum speed must be reached in at least 3 seconds;
In PWM mode, start from standby mode and reach 90% of the maximum speed in at least 3 seconds.
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
