200L pump not working

Because the 200 L and 500 L units are a different league, we'll grant them their own sub-forum.

200L pump not working

Unread postby lunarjetset » Wed Aug 22, 2018 12:16 pm

Hi,
the pump has stopped working - we can't hear any noise at all. Is there a fuse somewhere for it? I checked the connections and they are ok and the braumeister turns on ok,
thanks
Pete

Have you checked the impeller to see if it rotates freely, could be stuck

Thanks - I will check it but I would really expect it to make some noise which has happened before if the pump has got stuck. I will try opening it up and have a look...

Without seeing the pump, this is how I would diagnose the issue.

Keep the BM dry.
Run the pump in manual.
With a multimeter check the voltage on the line.
No voltage = controller or lead issue.
Voltage = pump issue.
You can run the pump without the head on.
A humming noise indicates stuck.
Give the shaft a twist see if it's free.
How long since it it was running?

Pumps in this configuration often have seal failures, where the drive shaft emerges. The liquid gets past the seal and then rusts in the pump while it is stored.

Tapping with a hammer can sometimes free.

This was a 3 phase electricity problem - not a braumeister problem! One of the 3 supplies in the electrics was faulty but it's all now fixed and working. thanks for your help!
