The performance curve of a type of jet pump is as follows:

From the above picture, we can see that:
1, the performance curve of the rotary jet pump is smooth, and the change of flow has little effect on the lift head (no pulsation of pressure output). Compared with the multistage centrifugal pump, the flow rate has great influence on the lift.
2, the working range of a rotary jet pump can be equivalent to the working range of various types of multistage centrifugal pumps. The use of rotary jet pump is quite convenient and flexible to adjust the production process, without changing the pump.
Explain：
(1) the rotary jet pump itself can work in the range of full head curve and has a wide range of work.
(2) to change the speed of the pump or to replace the receiving tube, the flow head curve of the jet pump will change, which is equivalent to the other type of rotary jet pump. Even if your process change requirement has exceeded the working range of the pump, we can simply meet your needs by simply adjusting the speed or replacing the receiving pipe, so it is not complicated to replace a pump.
