Zhejiang Dolay Pump Industry High-speed, High-efficiency And Energy-saving Deep Well Series Well Submersible Electric Pumps

                    Zhejiang Dolay Pump Industry High-speed, high-efficiency and energy-saving deep well series well submersible electric pumps

KATREENI deep well pump is powered by a permanent magnet brushless motor and equipped with an intelligent controller. It breaks the conventional design ideas and boldly adopts new structures, new processes, and new technologies to further improve the reliability and service life of the product and achieve reached the international leading level. More importantly, through the successful research and development of this project, the goal of energy conservation and consumption reduction can be achieved, responding to the worldwide call for energy conservation and emission reduction, and promoting product upgrading.

Large flow and high lift, excellent leapfrogging performance, its flow and lift exceeds that of conventional 4-inch well pumps, and the rotation speed is 6000 rpm/min .

The high-speed deep well pump uses an external frequency converter to allow the well pump and frequency converter to be combined with each other

Test:  Stable and continuous operation for three months, 100,000 start-stop tests without failure

Motor and Impeller

The motor speed is as high as 6000 rpm/min  and has a long service life.

The impeller lift is high and the single-stage rating exceeds 3 times the conventional rating.

Voltage and Frequency

It is light in weight, low in drilling costs, and does not require heavy equipment to assist in drilling.

Small size and light weight, the 11KW machine does not exceed 30KG

The wide voltage is mainly used for solar panel combination, gasoline engine power generation and household electricity use.

Unlimited frequency, universal AC and DC, automatic switching, built-in control system, automatic control of various problems, no need for any external frequency conversion control system.
