product details

High speed deep well pump

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 1/3, and its weight is 1/4 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 one invention patent and also have 11 patents for utility models, and 3 patents abroad, 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 92%), the PF up to 0.99, after deducted the comprehensive loss of controller, the final efficiency still higher that the well pump droved by single phase asynchronous motor.

Our pump can be powered by AC, DC and solar. If connected to solar panels, then it can be solar pump. Our successfully developed solar pumps can change frequency automatically. Input power can switch between solar and AC power automatically. Solar power can be fully used, which is more advanced than other solar pumps working in MPPT. Power can range from hundreds watt to thousands watt. efficiency of our pump is at least 20% higher than other pumps.

This pump is mainly used for all kinds of water supply and drainage, fountain , solar system and all other field requires deep well pump, widely used in industry , agriculture, petrochemical industry, medicinal industry and all kinds of water process. This pump has obvious advantages especially for those request high pump head and big power. It's a new generation electromechanical integration well pump, and it would be the future direction of deep well pump development.

Identification codes

Note: The permanent magnet synchronous motor series deep well pump needs to be equipped with a variable frequency controller to operate. The three leads of the pump cannot be directly connected to the three-phase power supply.
