Splitting pump output

I'm curious if a 8GPM pump can be regulated between 2 hoses. Different GPMs per hose ... how would that effect the PSI of each hose?

I'm thinking about running 2 hoses off 1 pump, 1 for a surface cleaner and one for a wand (detail work) at the same time. What I don't want is one effecting the others performance.

Sounds like it may take multiple flow regulators. First regulator set to 6GPM, second set to 2GMP.
 
We have split the gpm in the past when one person would let off the trigger it would jump on the other gun. Not sure how to stop that.
 
I am sure Paul or Russ will chime in, they are the pro's with this stuff.

I am sure they will recommend the green spring unloader (made to bypass a lot and for dual-gun setups).
 
What type of unloader do you have? Pressure Trap or flow?

From what I know pressure traps are way easier for two guns then flow due to not requiring 5-10% being needed for bypass.

Next thing you will have to consider is nozzle size on both the surface cleaner and wand. 2 gpm for a wand is a really small nozzle and probably isn't worth it. Your besy bet honestly is to find a small cold water unit and use that for the second wand. You won't have the surging as mentioned and you will have exactly what you are looking for.

I know surface cleaners work best witha constant pressure and gpm, I don't think splitting will leave you with the best results
 
Get one big motor and two big pumps.I dont think it can be done very effective i guys use there machine and everytime one would let off the trigger it would dump all the gpms and pressure on the other and unless you figure out how to use two unloaders off one pump that would be the only way to keep that dump effect from happening.One 8gpm machine with a guy pulling hose and 1 guy washing is much faster than two guys washing at 4gpms.

BINGO! The YU21405 is the valve to go with. What you do is get both guns running and set the unloader to just dribble through the bypass. That way, it's always in partial bypass, which it's designed to do, and the pressure will not jump from one gun to two. You may feel a quick flash of about 5% as the unloader rebalances for the change in flow.
 
Russ, is the green and blue spring not rated for long term hot water use like 195 or hotter for a long time?

I thought I read that about the blue spring but not seen the specs of the green spring.

This is what we do. That way we can run one hose to the roof, split off into two guns and go to work. If we need all 8gpm at one gun we switch to a larger tip on the one gun.

As far as I can tell, they're all rated for hot water...but who runs hot water through the unloader?
 
Good point Russ.

Thanks.
