Help: In what situations is it necessary to equip a pump with an on-site control cabinet?

1. Under what circumstances is it necessary to equip a pump with an on-site control cabinet? 2. When the process requires centralized control and interlock functions for the pump, is it necessary to have an on-site control cabinet? If not, what responsibility does the manufacturer bear for such requirements?
Generally, pumps require on-site control; what we have here is merely an operation panel used to control the pump’s emergency stop and start functions. Meanwhile, station control allows for centralized management, including frequency conversion and overpressure interlocks, among other things.
In our facility, all pumps in the pump rooms require on-site control cabinets; we have never seen any example without such cabinets； Regarding centralized control and interlock control, if the process requires a continuous supply of the medium, interlocks must be installed
It may be configured in combination with other devices to measure temperature and pressure.
In current manufacturing processes, two aspects need to be considered: the control room and local control. Under normal operating conditions, the equipment on site can be started and stopped from the control room; however, when the equipment malfunctions or a certain equipment unit is not in use temporarily, local control can be employed. Therefore, it is generally advisable to equip all equipment with a local control cabinet to ensure its safe operation
So, is the control panel used for one-to-one control, or can it control multiple devices at the same time? Is an operation column provided for each pump with a specific identifier? Thank you.
May I ask which department is responsible for determining the combined configuration with other equipment? Is it the process department, the electrical control department, or the pump and machinery department? Thank you
3# wkygaihua: Our water pumps are all installed outdoors. I asked the electrical control specialists, and they said that our pumps have very few control points, so there is no need for a control cabinet. But which department is actually responsible for deciding whether a control cabinet is necessary or not? Thank you
You need to see what kind of project it is and whether a workstation is needed
