9440 Pumps

[Carlos Arouche]

I have a 9440 with two different pumps, the first one smaller and the new and bigger one.

Both are with the impeller broken (the ceramic axis).

They are working, but a little bit of vibration is noticed.

How should I poceed to buy thos axis or impellers ? the axis is the same ?

Best regards.

They use different drive units, I would change the old one for a new pump, this would be the best solution. For the new pump you need 9420.047.
