Can replacing the magnetic coupling achieve the goal of reducing pump flow?

As the title says, a new user is asking a question – thanks! Lockhead circulation pump...
:Lol, let’s learn something: can a coupling actually reduce the speed?
It’s said to be for adapting to variable frequency, but it’s a bit hard to understand why the flow rate decreases
Theoretically, it is possible; if the magnetism is reduced, the power will also be reduced. To reduce flow rate, try cutting the impeller or replacing the pump.
Magnetic couplings, also known as permanent magnet couplings, can replace conventional couplings; moreover, by adjusting the air gap, it is possible to regulate the speed of the driven load. Of course, cutting the impeller provides a better energy-saving effect, but it is not reversible.
