View Full Version : Rotors and mp rotators... again

07-01-2012, 06:41 PM
I was looking up precipitation rates for mp rotators and rainbird 5000s the other day while programming a RB smart clock and it seems like they can be matched exactly.

It seems the sentiment here is using rotors and mp rotators on the same zone is a last resort. Why?

that's a huge plus for RB if the facts are there..

I'd cross a picket line in a heartbeat.

Rainbird 5000 rotor performance chart.


mp rotator performance chart.


Its kind of hard for me to believe an mp can put out the same amount of water as rb 5000 with a #4 nozzle, but that is what the chart says.

It can be done if all the heads were not installed with the biggest orifice on the nozzle tree. I hate when that is done. No, the 90s, 180s and 360s are not installed on separate valves either. If that were the case, I would not be betching.

i put at least one or 2 mp's on each job to catch any odd shape perimeters of the turf on the rotor zone.
at .7gpm for a 180 mp2000 and the same precip rate.
they work great for that stuff.
