Tested two pumps

I tested two extra pumps I got from Rumores today.  One is an IR Aro 66605J-3EB which has santoprene diaphragm, ball and check valves.  Which is good for soap products. The second IR Aro pump is a PD02P-APS-PTT which has teflon disk, check and diaphragm.  Which is good for harsher chemicals.

They both seemed to work just fine.  They were both set around 20 – 30 psi.

Flojet problems

Today, I opened up 5 flojet pumps.  I was thinking that maybe they would be easy to notice what the problem was.  The majority of the problems were with the check valve assembly.  I tried to piece together a couple and got three that probably will not work.  But I did try.  Greg, did say to just buy new ones.  But maybe if I replace them with new valve assembly kits the success would be greater?  I have not check them yet though.  I should be more positive.
