 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 10m3/h, 15m3/h,20m3/h, 25m3/h, 32m3/h, 40m3/h,50m3/h, 63m3/h,80m3/h,100m3/h,125m3/h,140m3/h,160m3/h,200m3/h,240m3/h,300m3/h, 400m3/h,500m3/h.


1m3/h=1000L/h=0.28L/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 100m 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
