Product Description

Product Overview
The inverter is built into the submersible pump motor in combination with high-end technology to avoid the trouble of the inverter getting wet and the danger of using electricity when the inverter is connected to the external power supply. Moreover, there is no need for external distribution box or pump room and other faci-lities. After the pump is connected to the power supply, it starts up soft within the set time (50 seconds), and the pump gradually increases speed, thus avoiding the damage of the motor shaft, pump shaft, coupling and impeller. When starting up, the current rises steadily a-nd the voltage does not drop, which protects the circuit and other household appliances. Through frequency increase of the inverter, the speed of the pump motor is doubled, so that the head of the single-stage impeller is up to more than 20 meters, and the pump efficiency is optimized, realizing the purpose of short pump shaft. less impeller, high head, large flow and more stable operation.

In addition, the variable frequency well pumo frequ-eng/ conversion device intelligent frequency constant power output, to ensure that the load isnot over, the best performance of motor efficiency temperat ure rise to maintain at the design point, truly achieve high efficiency and energy sawing.Even in accidents, and overload, overcurrent, overheating and multiple intelligent protection function, because in the process of operation, may have had foreign body suction mpeller jammed, current increases, and the built-in electronic intelligent detection device will instantly start, make the motor is not destroyed, directly reduce your economic losses All stainless steel international SP structure, strong corrosion resistance, protect the user's water health, more can be used in special fields.
