I'm going to be going 10 GPM at 3000 pretty soon. That's the main reason I'm going to the UAMCC event. Even my helper told me that I was going to go there to buy a new unit. I can't wait to get the Hydrotek off my truck and sold. Ill replace the Hydrotek on the trailer soon as well.
here is the friction loss chart. you lose about 300 psi per 100 feet of hose. Higher flow is always better, but from what I understand commercial requires more psi. If you are using 2-300 foot hose, that's 600-900 psi loss. http://www.catpumps.com/products/pdfs/993415A_REF_Hose Friction Loss.pdfFor cleaning commercial concrete with a surface cleaner, would you rather have 7.8gpm at 2850psi, or 6.5gpm at 3450psi? Same 22 hp engine on both, and assume the same burner with both (so the 6.5 would run a little hotter). With 7.8 would I have to upgrade to 1/2" hose?
I put together a 10 gpm 3000 psi unit for $3200. Its a 28 hp subaru efi and a udor gearbox combo.
Vince you had more problems with the hydroteks?
Vince once you go to those GX1036's you won't go back. I have 2 machines, one running just the GX1036 the other has a TS2021 as well. My burner is the restriction on the dual pump setup, that will get replaced in the future. They are a monster of a pump and assuming you have the power to push them you will be happy.
uh huh. 1800 sq ft driveways in 45 minutes, drive up to drive away.I'll always opt for more GPM vs. PSI.....We just went to 10 gpm at 2800 psi.....Crazy Fast washing for our area of expertise. 3/8's hose is fine for 8 gpm
That is cool Guy how is is that type pressure on hard surfaces.
