Reduce Water Pump RPMs

Saturday, January 16th 2021, 11:17pm

Hello Guys,
I have a question about aquastream ULTIMATE pump.
When I use aquasuite and configure pump for curve settings pump's rpms cannot go under 3000 rpm.
It is possible to put that pump on 2000 or 2400 rpm ? And how ? :huh:

Its about the limitation that pump. Any lower and they may stall, All depends on the individual pumps and their PWM controllers, this one is strictly voltage. Some will go a little lower than others but 3000 is the minimum on the spec sheet for that pump. If you were to put it on a variac and dump the voltage too low it will vibrate clean out of your case and onto the patio right before it just plain stalls.
