I have a dilling harris 1 bay self serve setup. Like others have said it will be cheaper to rebuild, BUT, you will be field engineering it all as dilling harris doesnt have much for these machines. In fact dilling harris almost doesnt exist. On Mine for example i replaced all those white pumps on the bottom with
flojets. From the looks of it i would just replace all of those
cat pumps to avoid issues in the future. What are they 500 each?? Parts will run almost that much. One is missing its head even. That alone to me makes it replacable just based on cost. Can you do this? Yes, will it be cheaper? Yes, but you will have a long period of fiddling with it and never really being sure of how long everyhing will last. Maybe have the motors looked at and serviced, i just had one done for 160 each. They strip it down and bake it then shave it and reinsulate it before painting it to look good. Replace the
cat pumps with new ones then hope for the best with the electronics. I dont think you can get replacements for those relay boxes between the kip valves anymore. My best guess is $5000 to do it all give or take, assuming the motors are all good that is. I know this, if someone showed me that picture and said they were throwing it out and asked me if i wanted it. I would take it and rebuild it then sell it...... so i say keep it and rebuild, unless you want the piece of mind of something new that wont need maintenance for a long period.....
