It does not require all time electricity and also high water pressure. The water level is sensed by two floats to operate the switches for controlling the pump motor.

Submersible Pump Wiring Diagram Control Panel Pumping Station
Water pump control circuit diagram. This project also work for save water and save electricity. Automatic water pump controller circuit. 1 shows the controller circuit. Automatic water pump controller circuit diagram. This diagram is for the circuit to empty a tank using two normally open float switches and a two pole changeover relay. Here is a simple automatic water level controller for overhead tanks that switches onoff the pump motor when water in the tank goes belowabove the minimummaximum level.
Some homes have a large water tank on high then pumping up the put on hold. Single phase submersible pump control box wiring diagram 3 wire submersible pump wiring diagram in submersible pump control box we use a capacitor a resit able thermal overload and dpst switch double pole single throw. Pressure switches are used on water pumps for the accurate control of the pump as it produces pressurized water. Convenient and savings but. This is a very useful circuit for household water tank. The bottom switch will be closed provided the liquid is above that switch point.
You can use up. Float switch control of a pump and pilot lights in circuit 3 a float switch is used to operate a pump motor. The pump is used to fill a tank with water. When the tank is low on water the float switch activates the pump motor and turns a red pilot light on. Automatic water level controller circuit. Here is the complete guide step by step.
The shorter steel rod is the water high sensor whereas the longer is the water low sensor. The circuit can be divided into two parts. Its very simple too. When you want to use just to turn on the tap at the bottom. The wiring connection of submersible pump control box is very simple. The liquid rises until the top float switch closes and energises the relay.
This project is environmental related project. Automatic water pump control circuit help to control water tank overflow. Let us consider two reference probes a and b inside the tank where a is the lower limit probe and b is the upper limit probe. One set of relay contacts connects the pump to the supply and the other maintains the relay on state while the level. Water reservoir automatic level control simple circuitry 12v supply. By means of a relay employed to drive a water pump this circuit provides automatic level control of a water reservoir or well.
Without the use of the switch the water pump would always be on or off. However with the pressure switch the pump can be adjusted to turn on and off at predetermined settings to control the pump and subsequent pressure. Controller circuit and indicator circuit. The two wire from the relay should be connected in series with the off switch of the water pump.
