The flow rate increases, while the head is low
This seems to relate to the series and parallel connection of pumps; it is specifically covered in chemical engineering principles
Why has the traffic decreased? ? Why does the head increase?

This is a bit different from paralleling pumps of the same specification
It’s just like resistance; with resistors connected in parallel, the total current flowing through is greater, and the total resistance is smaller. The flow rate of pumps connected in parallel is essentially the sum of the flow rates of the two pumps, while the head can be either high or low; otherwise, the pump with a lower head will not be able to perform any useful work, that is, it won’t be able to pump fluid out. In practice, the flow rates of the two pumps are adjusted by controlling the outlet valve of the pumps or the frequency of their motors.
