1.Main Features

• Silent operation: the silent hot water miniature circulating pump adopts advanced noise reduction technology, such as low-noise motor, vibration-damping design, etc., to ensure that the noise generated during operation is extremely low and will not cause interference to the surrounding environment.

• High-temperature resistant: the silent micro circulating pump body and internal parts are made of high-temperature resistant materials, which can withstand the corrosion and abrasion of high-temperature hot water and ensure stable operation for a long time.

• Miniature design: the mute hot water miniature circulating pump is small in size and compact in structure, which is easy to install and use and saves space.

• High efficiency and energy saving: adopting high efficiency motor and optimized fluid design to improve pump efficiency and reduce energy consumption.

• Safe and reliable: with overheating protection, overcurrent protection and other safety features to ensure the safety of the pump during operation.

2.Working Principle

Silent hot water miniature circulating pump drives the impeller to rotate through the motor, sucks the hot water from the inlet, and accelerates the hot water through the centrifugal force and then discharges it from the outlet. In the process of circulation, the pump can overcome the resistance of pipeline, so that the hot water in the system continues to circulate.

3.Application Scenario

• Family hot water circulation system: used in family water heater, floor heating and other hot water circulation system to improve hot water supply efficiency and reduce waiting time.

• Small heating system: in small heating system, the mute hot water miniature circulating pump can be used to circulate heating medium to ensure stable operation of the system.

• Solar water heating system: In solar water heating system, the pump can be used to transfer hot water from collector to storage tank to improve hot water utilization rate.

4. Selection considerations

• Flow demand: According to the actual demand of the hot water circulation system, determine the required flow range. Too much or too little flow may affect the operation of the system.

• Lift requirements: according to the height difference of the hot water circulation system and pipe resistance, to determine the required range of head. Insufficient head may result in unsuccessful circulation of hot water.

• Material selection: According to the temperature and nature of hot water, select the appropriate pump body and impeller material. For high temperature hot water, high temperature resistant materials should be selected.

• Noise requirements: according to the noise requirements of the use of the place, select the silent hot water micro-circulation pump with low noise characteristics.

• Brand and quality: choose well-known brands and high-quality products to ensure reliable pump performance and quality.
