4Inch Series Pump 4SZW10-60-3.

There is nothing comparable to this advantage: 

1,Multifunctional automatic protection under overvoltage overheated and overcurrent

2,Constant voltage and constant flow working model ,etc.

3,Timer switch and Multi-time period working model.

4,Network control model.

5,Downhole waterless protection

This type well pump is the most advanced pump,and it already awarded 5 domestic and foreign patents. 

For this high tech product promotion, now we are inviting outstanding area agent all over the world.

 Chuangmei developed a new generation high speed and high efficiency deep well pump, equipped with high speed and high efficiency DC brushless motor or high efficiency AC synchronous motor as the source of power. Its volume is 1/5,and its weight is 1/5 of other pumps in same specifications. The characteristics are energy saving, high efficiency and complete functions. It’s a new generation electromechanical integration well pump, also is the most advanced well used pump in the world.

     We acquired 6 patents of technical principle from the State Intellectual Property Office, has reported the international patent.

      This pump should be worked with our exclusive controller, owns frequency control, constant velocity and so on, so it can be pumped water under the work model such as constant pressure, constant flow, time swith, remote network operation and intelligent operation.

      The pump works both at 50HZ and 60HZ, and also can remain the head and flow unchanged under wide voltage, output constant when the voltage pulsation happens.

      As this pump used high efficiency motor(the max efficiency for motor is about 87%) ,the PF up to 0.99, after deducted the comprehensive loss of controller, the final efficiency still higher that the well pump drived by single phase asynchronous motor.

      The controller has AC input and DC input, also can be connected with solar panel, form a solar deep well pump. The efficiency of such solar pump is higher than other pumps more than 20%, with small in size, light in weight, easy to use, total management functions on solar, battery and pump.
