Product Description

 Product name:Automatic Electronic Constant Pressure Water Supply Equipment



Automatic frequency conversion water supply

The automatic frequency conversion water supply equipment is a new generation of products with advanced foreign technology combined with fire, life and production water. It adopts microcomputer programmable control technology, according to various conditions of water supply pipe network and water source, by micro Computer control regulates all kinds of complicated work and realizes intelligent water supply.


Fully automatic variable frequency constant pressure water supply equipment is an ideal energy-saving water supply equipment with good energy saving effect, compact structure, small floor space, stable and reliable operation, long service life, flexible design, adjustable water supply pressure and large flow. Can be small, can completely replace the water tower, high water tank and various pneumatic water supply equipment, can completely eliminate the secondary pollution of water quality.


The automatic frequency conversion constant pressure water supply equipment is also used to transform the original old pump room equipment, and the same can achieve the purpose of high efficiency, energy saving and automatic constant pressure water supply after the transformation.



1. High efficiency and energy saving.The automatic frequency conversion constant pressure water supply equipment can automatically detect according to the actual water consumption and the use pressure of the user, and adjust the rotation speed (power consumption) of the motor, so that the equipment is always in a high efficiency working state.


2. Water supply pipe network pressure is stable


3. Small footprint, low investment, short installation period


4. Full protection function, safe and reliable operation, easy to operate


5. Water supply function is complete, insurance factor is high


System function and description:

1. Pressure adjustment: freely adjustable within the performance curve of the pump

2. Automatic shutdown: the system can automatically stop after 20 seconds without water, and the pressure will not deviate from the set value by 1% after shutdown.

3. Normal water consumption: When the system pressure is lower than 85% of the set pressure, the pump starts up automatically and maintains constant pressure water supply.

4. Water shortage protection: When the pump's full-speed running pressure still cannot reach 65% of the set value, the pump will automatically stop running after 30 seconds.

5. Other protection: overload, over current, high and low voltage protection, etc.


Installation environment and instructions:

1. Ambient temperature: 0-45 degrees Celsius cuts the communication is good, below zero, please do a good job of heat preservation of the pump pipeline.


2. No water droplets, steam, no floating dust, metal particles in Egypt.


3. No sunlight, high temperature and serious dust.


4. Locations without corrosion, flammable gases and liquids.


5. Locations without vibration and electromagnetic noise interference.


6. Maintenance, check the location of the capacity.



Scope of application:

1. Centralized living water supply system for residential areas, residential buildings, and villages and towns.


2. Circulating pumps and cooling water supply systems for various types of central air conditioners.


3. Living water supply systems for high-rise buildings, hotels, restaurants, etc.


4. Integrated market, office building, commercial building living water supply system.


5. High-rise building hot water supply and hot water heating system and fire water supply system.
