For a centrifugal pump with two units in operation and one as a spare, can both pumps be started at the same time when starting the pump?

For a centrifugal pump with two units in operation and one as backup, can both pumps be started at the same time when starting the pump? Can the two pumps be shut down at the same time when shutting down?
It is possible to start both pumps at the same time, which improves the efficiency and stability of water supply or drainage. However, when shutting down, it is best not to turn off both pumps at the same time; instead, one pump should be turned off first, and once it has stopped completely, then the other pump should be turned off, in order to avoid issues such as pipeline shock. .
