So my SWC 250a (non-cone skimmer) pinwheel has finally needing replaced due to broken pins. However it seems there have been many changes to the SWC skimmers w/askoll pumps (since going to the cone design). The impellers are now attached to the shaft w/metal piece where mine just has a hole to push the shaft in "interference fit". I tried an entire rotor assembly from a newer cone 300a which looked EXACTLY the same, uses the same white volute, even measured everything w/micrometer and is the same in all ways except for the metal piece holding the pinwheel on. But it did not work in my Laguna block, it jerked back n forth, spun the wrong direction and just plain didn't work. My motor block (which from the sticker I believe may be from 2004) seems to operate just fine with my original rotor assembly it's just that the pinwheel has 10-20 missing pins now. I've also heard that Hagen has made some changes to the Laguna Max Flo 1500 pump but what exactly I don't know. I know they reduced power consumption but what else ?, I've e-mailed them but no response. So what to do. I have a LG system w/lots of coral that's really missing the powerfull skimmer. I need serious HELP!!!!!!!! I'm down to just replace the entire pump and rotor (pinwheel, shaft, magnet, ect) but want one with the white SWC pinwheel. Most of the people I know who have found themselves in a situation with their SWC cone pumps just replaced the Askoll w/a BB HY-5000s but I just can't do it. I just want to return it to it's former glory. PLEASE HELP!!!!!!
