At the outlet of the pump, there should be a one-way valve.
I looked it up and it's probably a diffusion filter.
I agree with the point above. It is a one-way valve. It is used for slightly larger flow pumps such as double-suction pumps. The outlet should have a slow-opening and slow-closing waterproof hammer structure~~~But I can’t see the feedback pipe? Is it built-in? Waiting for the expert’s answer~~~~~~~~~
The reasons are as follows (according to common sense): 1. The opening here of the pump is generally the outlet. ； 2. There is a pressure gauge at the outlet of the pump, but not at the inlet. Doubts: Without being able to go to the scene, it is impossible to obtain accurate information.
1. Double-suction pumps usually enter from the left and exit from the right. According to common sense, this should be the inlet. 2. The water pump inlet should have a straight pipe section requirement, but there is no requirement here. 3. So the equipment in the picture should be a diffusion filter. 4. In addition to functioning as a filter, it is also used to solve the problem of insufficient straight pipe section in front of the pump.
General centrifugal pump inlet filter outlet check valve.
