this one may be better -

shows settings for one pipe, or looped opperation.

it may be interesting for you to stick a pressure gauge on it also, but possibly not, if youre never going to be pumping at pressure.

Next problem.

I have a motor EOGB M02-1-90-13 (brand new one, for cheap!) and aforementioned Danfoss BFP 11L3 pump (I understand L means left hand, rotates anti-clockwise), the two fit together but need some form of coupling to join them.

Is this the right coupling? Are Riello and Danfoss pumps interchangable?

Or something like this?

(nearly a fiver for a bit of plastic ain't happening, I'd rather print one)

A bit of hose and two jubilee clips works quite nicely if you're not too bothered about a 'proper' engineering solution.

Hehe I like your thinking!

Sadly this is not a shaft to shaft coupling, the pump has a shaft with a flat and the motor has a recessed pocket in the back that takes some keyed coupler.
