We used to offer a 12 psi pump for these reasons. But after about 3 years and not a single front seal failure that I was aware of, we discontinued the 12 psi pump.
As to date, I have been aware of 2 or 3 front seal failures of close to 800 pumps sold.
However, we may start offering the 12 psi pump again.
Just an fyi though.......the Cummins low pressure pump used in some of the ag applications, runs 18-20.
