Brief Introduction

Automatic backflushing control system is made up of the electromagnetic water valve,three -way backflushing valve,filter units,hydraulic sensor,alarm,pressure holding valve,water pump and so on,which are linked by the programming software through input and output signals of controller. It can automatically take turns to clean each filter online.Meanwhile,it can uninterruptedly provide filtration water.So it achieves the purpose of unmanned automatic control.The controller is equipped with LCD which can show real-time operation status of equipment.


Typical Application

Apply in backflushing disc filter,to form automatic backflushing disc filter system;

Apply in shallow dielectric filter,to form the automatic backflushing shallow dielectric filter system.


The main function

1.The controller can be set three kinds of backflushing trigger mode:timing trigger,start,inlet and outlet pressure difference trigger,manual trigger start;

2.The controller is equipped with a differential pressure sensor and water pressure connecting port for inlet and outlet,can be determined immediately the difference of water pressure; is embedded pressure sensor zero calibration.when calibration,it is needed to disconnect the water pipe; the time for disconnect embedded controller,it can also be triggered by an external differential pressure sensor that enters a dry contact signal;

5.The controller can be separately count the times of backflushing for the timing start,the differential pressure start ,the manual start;

6.the controller can be set the times of backflushing cycle triggered by differential pressure .When the times of backflushing cycle triggered by the differential pressure exceeds the preset times,the backflushing will be stopped and give an alarm.The alarm problem will be displayed on the screen.The pressure difference could not trigger backflushing,the subsequent backflushing will only be triggered by the timer start;

7.The controller can output an external alarm signal,the external alarm used to alarm,appeared infinite cycle backflushing;

8.The controller can output a control signal of the main pressure holding valve(or on-off valve);

9.The controller can set whether the pressure holding valve working ,and the delay time of opening backflushing valve after the pressure holding valve start to work;

10.The controller is equipped with customized LCD screen and keyboard for user to interact and real-time reflect the equipment running status,user-friendly design of control display interface,operation is simple and easy;

11.The user can set flexibly the backflushing time,the delay time within the backflushing valves,the delay time of the differential pressure detection;

12.Low voltage waiting function,when the pressure sensor detects the outlet pressure below the set value,the controller stops starting backwash and gives a low voltage alarm on the display until the water pressure reaches the set value.



1. Integrated structure design,IP66 protection level;

2. AC110V/220V power supply mode;

3. There are two models to choose including a maximum selectable 16 control filter unit and the maximum optional 8 control filter units;it is flexible selected control from 1-8 or 1-16 filter units;

4. Flexible configuration with 2-8 or 9-16 control valve station according to the number of filter units;

5. Configure a backlit pixel screen to display text menus.
