Centrifugal pump operating conditions
Centrifugal pump operating conditions
(OP)
Hello,
I really need your help:
I have a liquid filling machine that produces coolant fluid. the centrifugal pump (its parameters i can provide) sucks the liquid from the bottom of an IBC container. the bottom of the IBC is more or less at the same hight as the pump.
this is a small batch system that is not very operational since the demand is high for the coolant fluid.
Therefore a tank was constructed[4m3]. when it is full, the liquid level is 4 meters above the pump.
My worry is that because of the big hight difference the liquid pressure will over-flud the pump even if it is not operating and the liquid will pour out of the machine without any control.
I havent tested the tank yet, so my question is what do i need to do in order to know will the pump hold the pressure or not?
Thanks very much.

RE: Centrifugal pump operating conditions
Its not clear what your pump connects to.
If its an open end, then without valves, if the liquid level in the tank is higher than the outlet, a centrifugal pump will let flow through.
You might need a simple pressure control valve to stop flow when the pump isn't running.
Not quite enough info to say any more.

Also: If you get a response it's polite to respond to it.

The pump is connected the the tank, by a valve. its is a open end pump since its outlet fills the bottles directly.

To repeat, centrifugal pumps will not "hold" pressure.They might provide some resistance to moving how, but not a static flow.
Does this help?

I was thinking about placing additional vavles between the tank and the pump. it is the easiest thing i can do. not sure if it will work.

I think you might be seeing problems where none exist, but without details it is not easy to say much more.

They are not great but this is the best I could do.
