Time Taken to stop a pump?
(OP)
I want to ask if there is an ESD interlock action to stop a pump due to any circumstances like very low level switch in a separator how much does it takes to stop the pump after the signal reached??

What type of pump, size and driver type do you have?

Thank you for your quick reply
The pump is centrifugal. it delivers about 300 m3/hr of contaminated water- electric motor driven.
I want to know only is that occur instantly or it takes seconds or it takes minutes?

Depending upon the system the pump could be driven by the fluid in turbine mode.
You cannot guess it.
If it is critical fit a VFD with dynamic braking. Make sure you have safety devices for that time you lose power and the pump trips but the VFD isnt working.
SOme major installations have flywheel generators in place so that on loss of power they keep power on critical equipment to allow controlled stop. An electro mechanical UPS if you like.
