All of the pumps we make are continuous duty....the motors are rated (per the motor mfg) to last anywhere from 3-5yrs when running 24/7 The smaller motors, like the 809's, have a thermal overload built in tothe motor so if they overheat it will cut power until it cools down then it will restart...

Its definitely a cool little unit...they came by us here at March to use our test tank and equipment to measure the performance. :cool: Its their product so i wont be giving any details away ;)

Yes there's normally a teflon washer there between the impeller and the pump head. If that's gone then the impeller could be rubbing against the pump head causing the issues. If you are in a bind and want to do a quick fix try going to the local hardware store and finding a stainless...

If you have a cell phone with a camera you should be able to record a short clip and shoot it off or text it to an email address. :) have you taken the pump apart at all? maybe the thrust washer inside is gone and the impeller is rubbing against the pump body?

De-coupling would be a go - no/go situation....if the mag-drive de-couples then you loose all pumping action. Can you make a video of it during the issues and email to me? my work email is wwojcik @ marchpump.com (minus the spaces so the internet spammers dont harvest it :D )

Have you taken the pump head apart to check inside? Maybe the thrust washer is worn out and allowing the impeller to contact the pump head? If you want to send it back to us here feel free to give us a call....ask for Wayne in the service dept and tell him you want to send it back for evaluation...

No, wires 2-J-5 are all connected together and insulated with a wire nut. There is a green ground screw inside the junction box...

Hi all, haven't been on here in a while as i haven't been getting any notifications in any of the threads i was subscribed to :confused: but anyway...fist thing i would do is verify you are getting air in the plumbing.....easiest way to do that would be to put the discharge line under water and...

Maybe i can help :cool: The first pump is the 815 model....the second pump link is an 809-HS version...they both use all the same parts but the 815 has a slightly bigger impeller internally, and has a stronger magnet on the impeller as well.....most brewers seem to prefer that model as it...

the washer can be considered a wear item but it depends on how its used....the reason it wears is because the impeller is getting sucked up against it....usually from a lack of fluid on the inlet side....like the piping being too small or too many 90*'s in the system, or a valve thats smaller on...

Um.... We don't need to "combine forces" with a FORMER distributor that went to China and COPIED our pump design! :rolleyes:

The issue that you may run into is when there is no restriction on the outlet side of the pump and you don't have enough head pressure on the inlet side of the pump....the pump will try and pump more out then whats coming into it....and a number of things "may" happen.....you could get some...

put a block in there just high enough to fit the orientation of the pump head so the outlet is pointing straight up at your face....put a 90* elbow on the inlet so its easier to plumb.....then you can add a "T" fitting on the outlet.....the side port goes to your chiller lines....the top port...

Wow that's cool...i've never seen anything like that before. I must say you guys get crafty :D Besides opening up the pump to verify that the thrust washer is there, the only thing i can tell you to possibly change to help things would be to get a wooden block and raise the pump up enough to...

Yeah i dont know enough about that to say one way or the other...but if it works then go for it :)
