Tunze 6305.701 Flow Pump

[zwieseldave]

Greetings,

I wonder if anyone has the Tunze 6305.701 version of of the 6305 and tell me if the impeller actually has a bit that goes into the cage, from pictures the 6305.700 has a spindle that goes into the cage but the 6305.701 does not seem to have.

Can anyone confirm this, there doesn't seem to be a manual on the Tunze site for either versions.

Thanks

Dave
