Rotary jet pump instead of multi-stage pump?
Thread Content
Install an old multi-stage pump with many faults and replace the multi-stage pump with a rotary jet pump. This is the first time I saw this kind of pump. I didn’t understand its principle after looking at the picture. Have you ever used this kind of pump?
I just went to Baidu and combined with the pitot tube principle, I estimate that the key points of the rotary jet pump working process are as follows: 1. The opening at the end of the header is opposite to the tangent direction of the rotation direction of the rotor cavity. In this way, the fluid enters the header opening under the rotational pull of the rotor cavity, thereby converting the kinetic energy of the fluid into potential energy. 2. After the fluid enters the rotor cavity from the entrance of the rotor cavity, it is mainly driven to rotate by the blades at the rear of the rotor cavity. 3. After the fluid in the rotor cavity is extruded from the header, negative pressure appears inside the rotor cavity, so the fluid continues to enter from the inlet of the rotor cavity. It can be seen that the rotary jet pump needs to be primed. The above is my personal understanding after checking Baidu Encyclopedia. If there are any mistakes, please point them out.
I have relevant information, please send me a private message if you need it
The lift is very high and our factory is used to transport coal tar.

At present, this kind of pump is used in many main processes, and the feedback is very good. There are many advantages, I would like to discuss them in detail.
Pitot tube pump. Small flow and high head.
