1)How to convert HP into KW ?The conversion formula as :1HP=0.74KWfor example: 3HP=3x0.74KW=2.22KW
2)How to choose the power of your pump controller?Normally we need choose bigger power to run the water pump or motors,.If the pump rated power is 4KW,Pump controller should choose 7.5KW.For Submersible pumps which used in the deep well,please check with us first .3)Can I have the samples of your pump controller ?Yes, we can send you the pump controller samples for your testing .4)Can you provide OEM or ODM ?Yes,we can make the ordes according to your detailed request.5)what is your delivery time?It takes 3-5 days for sample orders,and 15-20 days for orders
