4inch~*2inch deep well electric water pump  

electric water pump|electric water pump 5gallon

There are six series of submersible pumps produced by our company, as follows: 

QJ using condition:

1.  **0V voltage deviation is no more than ±5%,frequency is *0HZ, three -phase power deviation is no more than ±1%.

2.  Motor cavity must be filled with water.

3.  The first stage impeller of the pump should be more than 2mm below the moving water surface, pump unit should be less than *0m below the static water level.

4.  The distance from the motor bottom to well bottom must be more than 3m.

5.  Water temperature should be no more than *0°C.

6.  Sand content of the water ( by mass) should be no more than 0.*1%.

7.  PH value of water 6.**8.5.

8.  Hydrogen sulfide content of the water should be no more than 1.5mg/L.            

9.  Chloride ion content of the water should be no more than **0mg/L.

*0.  Water yield of water source should ensure the requirements of pump continuous working.

How to select a model:

1. You need know your flow request

Flow***-means how much water you want to pumping per hour. Our model rated flow is *0m3/h, *5m3/h,*0m3/h, *5m3/h, *2m3/h, *0m3/h,*0m3/h, *3m3/h,*0m3/h,**0m3/h,**5m3/h,**0m3/h,**0m3/h,**0m3/h,**0m3/h,**0m3/h, **0m3/h,**0m3/h.

1m3/h=***0L/h=0.*8L/s, 1m3=1Ton.

2. You need know your head request

Head****-means how far or how high you want to pumping.

The head= vertical length + pipeline lose.

Vertical lenght= the distace from inlet water level to outlet water level

Pipeline lose= per **0m pipe will lose 2~3m head.

(If you need install the valve into the pipe, please tell us, it also effect the head.)

3. Your well diameter.
