Product Description

1.Description of Electronic borehole pump controller 

A series automatic pump control panel has a robust and waterproof stainless steel enclosure to prevent water ingress. 
The enclosure has a high IP rating to ensure it can withstand exposure to water and dust. Common IP ratings for outdoor electrical enclosures are IP55 or higher.Cable entry points are equipped with sealed cable glands to maintain the water-resistant integrity of the enclosure.

1)How to convert HP into KW ?
The conversion formula as :1HP=0.74KW
for 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
