Pump problem...
I have a Laguna Powerjet 7000. It stopped working so I replace the impeller
and bushing. I ran fine, then when I unplugged it, and restarted it, it doesn't pump. I pulled it apart and pulled out the impeller. Everything looks fine. Before I reseal, I checked if it turns. Yep... until I unplug, then replug. The impeller (still exposed) is turning erratically... almost like it wants to backwards while turning forwards. So it kind of jiggles, but manages to turn in one direction not achieving much. Anyone know what's up? - Prometheus |

Anyone know what's up? The impeller has separated from the magnet, sometimes you can epoxy together again... but better to replace. jay Thu Jun 03, 2004 - Prometheus |

It may be due to the rotor losing its magnetism. Carl |

I had a Laguna Utility that had the same problem once. I had to leave it running
and then put the cover back. That was the only way to make it pump. It doesn't do that any more. Prometheus Xex wrote: I have a Laguna Powerjet 7000.

Sounds like it may be a broken impeller shaft.
I fixed mine with some good old JB weld. It's run longer with the weld than without it. |

Yep... it spins free (with a bit of magnetic resistance).

Anyone know what's up? - Prometheus The solution probably is a new impeller-magnet assembly. Last fall I noticed that the tip at the the end was worn and for $28+ shipping got a new one at www.thatpetplace.com. The price may vary because my Laguna is the 5000. Happy water gardening. |

Symptoms would be it will often need a flick to start it up and once running it will be down on power. I think you said it was doing that. -- Regards - Rodney Pont The from address exists but is mostly dumped, please send any emails to the address below e-mail ngpsm4 (at) infohitsystems (dot) ltd (dot) uk |
