What type of pumps allow idling?

As the title suggests~~~~~~· What type of pumps can run idle?
Why spin idly? It’s not a fan. . . It depends on its structure; pumps with double-ended mechanical seals and cooling water can run without issue even when idle, but other types need cooling or lubricating fluids in order to operate without load. Take a look at the pump’s operating procedures, sir! ! !
:Hello, Mr. L! There must be applications for this pump if such a question is raised. . .
The vacuum pump can run idle. Pumps for transporting liquids basically cannot operate at idle. Peristaltic pumps can allow short periods of idling.
This is an interesting question. I also want to know which ones can run idle. Doesn’t running idle without any medium pose a risk of damaging the mechanical seal? ?
It seems that diaphragm pumps can also run idle.
Running a diaphragm pump idly for a long time should cause the diaphragm to deform excessively, thereby reducing its lifespan
I consulted two reputable pump manufacturers in China, and both said they were unable to produce it. I want to increase the gap of the mouth ring a bit; using a dry gas seal for sealing should work, right? :Q
What does the author mean by idling? No liquid operation? I personally have not heard of any pump that can operate without liquid. Only some pumps can transport both gas and liquid, such as certain positive displacement pumps, vortex pumps, hose pumps, etc.
I want to ask the original poster why it’s running idly; what is it used for? Ordinary gas pumps can run idle, such as vacuum pumps; liquid pumps, on the other hand, cannot do this. However, running them idle for a short time isn’t a big problem. When a centrifugal pump runs idle, it functions like a fan, which is not good over an extended period of time!
For most pumps, it’s not about whether they can run idle; the key factor is the length of time they remain in that idle state
