I have an older model Ventura 150 that had the Clark pump
factory rebuilt in 2007. Over the years the pressure has been slowly dropping and after being pickled for the past 5 months is now running about 35lbs. With a 4lb shift.
I have detailed tracking info and for many years it has been running about 50lbs. A new shurflo pump
was installed last year with no noticeable difference on pressure.
There is sometimes a small squeal noise
on the shift.
PPM is now climbing and about 350ppm
Total hours on the unit is > 1000
Have traded some emails last year with Katadyn
and they are suggesting that the clark pump should be rebuilt.
I have an older rebuild
seal and o-ring kit that is 12 years old. I thought I read that the newer rebuild
kits have a different type of o-rings that will last longer.
Do the newer o-ring and seal kits have new improved O rings?
Is there a online manual available that would show the steps required to install new seals
and o-rings? Is so can you point me to it on the web?
Thanks for your comments
