Checkvalve failure

[dvldoc]

Good post, I have always said that these do not run at 300psi no matter what some kit makers might claim. Here are our new pumps numbers for pressure with a check vavle in place but not installed or under boost.

I will have to disagree with them with saying these cannot hit 200psi at 12v no but these will take up to 15v with no problem.

Test conducted with a snubbed 3" Glycerin-Filled Gauge with NIST Certificate. Keeps things nice and smooth with no guessing on accuarcy.

12-30VDC Power supply at 13.25 volts. All numbers rounded down to the nearest multiple of 5.

M2 230psi
M3 225psi
M4 215psi
M5 190psi
M7 180psi
M10 170psi
M12 Not tested (didnt have one handy here on Guam)
M14 155 psi

Of course you would have to subtract the boost against the head of the nozzle for final figures. Our check valve is 16psi cracking pressure.
