Product Description
20S is a single phase LED digital display single water pump control box, specifically designed for residential and commercial 240vac pumps. Using high quality import microprocessors, this controller uses our float switch or probes to gain water level signal,as well as electric contact pressure gauge or pressure switch to gain pressure signal. For wastewater drainage ,the controller starts from high level,switches the pump off when the water level gets down to the low level.For water supply,the controller starts from low level and switches the pump off when the water level gets up to the high level.
Typical application scenarios:
-Agricultural irrigation/ pumping
-Pressure Booster Systems
-Waste water treatment
-Water Tanks/Wells
-Drainage System
-Cooling Towers
-Flood Control
-Fishing Boat

1)How to convert HP into KW ?
The conversion formula as :1HP=0.74KW
for example: 3HP=3x0.74HP=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 orders 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
