This type of pump achieves constant pressure water supply within a certain flow range, without the need for a frequency converter, by adjusting the outlet width of the impeller of the water pump itself. There are two hydraulic cylinders used to push the impeller forward and backward. The hydraulic control components are used to control the hydraulic cylinder. The constant pressure intelligent control electrical cabinet receives the pump outlet pressure sensor signal and commands the hydraulic system action based on the set pressure. The displacement sensor is used to sense the change in impeller outlet width. This type of pump is also known as an online variable displacement pump, which is highly integrated and intelligent.

Widely used in various fields such as petroleum, chemical, power, metallurgy, mining, ship selection, light industry, agriculture, civil and national defense.

We make the split case pumps with both special characters" intelligent and energy-efficient".
