It varies. So not really.

On my EWP very rarely runs at 100%, the davis Craig controller with pulse the flow.

It's a rotary, better safe then sorry. Go for the highest rated.

Why do you want a EWP?
Because mech drive has to many downsides...

this way you have a constant flow cooling the engine better in situations like stop and go traffic where your idling and the pump isnt spinning much, and it stops cavitation at high rpms
