| I've seen them on a lower tech "Watt meter" at 276watts, so that is about what I would expect. Its a lot of energy to expend in backwashing, especially if you have multiple units. The DIY microstrainers I am running on my pond are using less flow but still doing a good job of cleaning, they are 692gph pumps at 25 watts doing the backwashing from a fixed arm and rotating drum. The Answers rotating arm uses 1800gph and AES's VMS stationary arm needs 60gph. |
