No, this is a centrifugal pump and blocking waterflow won't
cause it to overheat. Jamming the motor would but blocking
the flow on a centrifugal doesn't jam the motor.
Anyways, Vortexes run a bypass circuit, that's why you can
get it to charge with diatoms by clamping the output hose

No, it's direct coupled.

All electric motors heat -- the energy efficiency ios no
where near 100%. The Vortex kgets warm but not too warm to
touch under normal operation.
