Does the outlet of the centrifugal pump bending upward again after going upward not only look unsightly but also pose other potential problems?

The pipeline length has been increased, resulting in greater resistance due to the two elbows.

Hidden dangers? Strictly from this perspective, sedimentation here in this U-shaped area causes blockage. Is it designed this way to have a liquid seal?

1. It will increase the resistance at the pump outlet. 2. The pump’s head pressure may be affected. 3. Liquid will accumulate at the liquid seal area. Thinking from another perspective, there is inevitably a U-shaped bend in the pipeline after the pump; currently, this U-shaped bend is simply located at the pump’s outlet.

Increasing the tube resistance may lead to fluid accumulation

Generally, there’s no major issue; some equipment connected to the ground has this characteristic, just make sure to drain it properly

It’s fine if the medium is a solution; the problem is that the pipes can’t be emptied properly. If a slurry is used, it will settle and block the pipes

Is it necessary to install a U-shaped bend?

Increased resistance, reduced head, more erosion sites; purging and displacement may not be thorough

In actual production, I have not seen pump designs and arrangements of this kind; I have seen designs with U-shaped pipelines, or pipelines that ascend in a spiral pattern； If designed in this way: 1. A drain must be installed at the lowest point of the U-shaped pipeline, to allow liquid to be drained during standby or maintenance periods, thereby preventing liquid accumulation, freezing, and blockages (liquid is drained from the lowest point, while air is vented from the highest point) ； 2. An increase in the resistance in the pump’s outlet pipeline leads to a decrease in the pump’s head pressure. As a result, the current drawn by the pump increases during operation, leading to more work being done and thus an increased power consumption ； 3. If the material contains dust, particles, or fine residues, it increases the erosion at the bends in the U-shaped pipes; prolonged erosion can lead to leaks, thereby reducing the lifespan of these pipes ； 4. From the perspectives of design philosophy and energy conservation, such a design is unreasonable and unscientific. If such a design actually exists in practical production (excluding technical upgrades), I would like to verify the truth as well. Thank you! The flow rate can be restricted by using a flow control orifice plate ； If the head is too high, a suitable head can be selected.
