Product Description
1. Description of Pump Controller
The 20Y automatic pump control panel is specially designed for 1-phase single Home water pump 0.37-3KW. The most basic difference between 20Y smart control unit and similar ON/OFF control units is that it doesn't need any level electrode or floater if desired. It protects the pump very sensitively against dry run without the need for any level electrodes or floater. This model is a control panel suitable for use in all situations where the operation, control and protection of the smart submersible pump and surface pump is in question.

Frequently Asked Questions
How to convert HP into KW?
The conversion formula is: 1HP = 0.74KW. For example: 3HP = 3 x 0.74KW = 2.22KW.
How do I choose the correct power for my pump controller?
Normally, you should choose a controller with a power rating equal to or slightly higher than the motor. If the pump rated power is 4KW, a 7.5KW controller is often recommended. For submersible pumps in deep wells, please consult technical support first.
Are samples available for testing?
Yes, we can provide pump controller samples for your quality and compatibility testing.
Do you support OEM or ODM services?
Yes, we can manufacture orders according to your specific detailed requirements and branding needs.
What is the standard delivery time?
Sample orders typically take 3-5 days. Bulk orders generally take 15-20 days depending on the quantity.
What kind of signal modes are supported?
The unit supports Level float switches, Level probes, Pressure switches, and Electric contact pressure gauges for versatile operation.
