@Grizz and I did some testing this afternoon on equipment. Most I had done before but I wanted to show him and to verify @Innocentbystander 's comments. Brandon has pics or videos of all the below. Machine rated at 8,
Using a 15 gal enclosed container the following are real numbers on machine with 850 hours on it and running through 250’ of 3/8 hose.
Pressure at nozzle using yellow tip 2800 psi - perfect
Flow using yellow tip 7.3 gpm - @Innocentbystander is right
Flow using m5ds nozzle 8.6 gpm
Flow using m5ds nozzle running through the injector - 7.3 gpm
PSI going through injector using yellow tip 2400 psi - good reason to make sure you’re bypassing your injector when doing concrete.
Guys, all these tests were done in less than 10 minutes. Learn your equipment.
