Regarding the connection issues of the pump’s inlet and outlet pipelines – Urgent! Urgent! Urgent!

Thread Content

I currently have a pump with DN150 inlets and outlets. I want to connect a DN300 pipeline to the outlet; is it possible to use a reducer that changes the diameter from 150 to 300 right at the outlet, and then connect the DN300 pipeline thereafter? Seek expert explanation! ! ! !

The outlet of the pump must be smaller than the inlet; you can install a valve directly at the outlet, followed by a reducer, and then use a 300 mm pipe. This not only makes operation easier but also reduces installation costs.

Absolutely. Agree with the person above. One thing to note is that if it is a pumped suspension, the flow velocity at the valve will be very high, so the issue of valve wear needs to be taken into consideration

If it’s temporary, that’s fine. Generally speaking, either the pump you chose is too small, or your subsequent equipment is too large, resulting in a mismatch. If you scale it up, your head pressure will be lost. If you further reduce the diameter at the inlet of the equipment, the loss in head pressure will be excessive; moreover, when the pump stops operating, water might overflow from the pump tank. You’ve become completely outrageous; it shouldn’t be a good choice.

It has become too large; I don’t know what the purpose is. Head shouldn’t be an issue, but the resistance is too low; if no control is implemented later, the pump is likely to experience overcurrent. Of course, from a mere connection perspective it’s possible; there are reductions from 150 to 300.

It is completely feasible from a technical standpoint, but safety issues need to be considered carefully.

In this way, the flow rate and the pipeline size do not match, which makes overloading likely; it depends on what size the pipeline at the end is – QQ1013087982
