  OR6500 Impellor explosion

  Posted: January 27th, 2012, 1:22pm CST by viper357

  So, last night was a bit busier than normal for me, I had a small problem with my big return pump. It's an Ocean Runner 6500. I got a phone call yesterday afternoon while waiting to pick up my daughter from her afterchool activates, "Dad, something is wrong with the tank", :eek: I honestly think that is the worst phonecall one could ever receive, you just know it can only mean impending doom and lots of clean up work to do. So anyway, apparently all of the water was still in the tanks, so that was a bit of a relief.
  
  Got home and found my return pump was not working. Weird. Tried to spin the impellor, it felt a bit tight and not very smooth so I thought maybe something had got jammed in there. Out came the towels and so started the horrible operation of contorting my body into all manner of weird positions to remove the pump from the sump, these pumps are monstrously huge and frikkin heavy.
  
  And here was the result of my investigation....an exploded impellor!!!
  
  
  
  
  
  
  
  
  
  How does that happen? Twice? Yes twice, I have 2 impellors from OR6500 pumps that this has happened to.
