Sanitary rotary syphon

[peterpiper]

These rotary syphon pumps look a neat idea.

Hand crank operates the planetary gear pump, then a half turn starts or stops syphon flow. And it's just a (removeable) silicone tube to clean, which sounds much better than the other auto-syphons I've seen.
Just not sure, what diameter silicon tube it uses, or would fit.

But, is anywhere selling them to the UK, at the moment?
The BrewEngineering etsy shop, where there's also a video, seems on long term holiday.
Siphon pump

I would refer to that as a peristaltic pump if that helps with finding one? But they are typically used for controlled dosage not bulk transfer.

If it's a siphon pump, it'll just be used to prime the siphon, not necessarily do a bulk transfer. Presumably once gravity takes over the siphon, you can stop pumping

It also looks like the kind of thing it would be easy to 3d print if you have a printer

 

[Caramel Ox]

Oh I see what you mean, just to start a siphon. Couldn’t you just use a big syringe?

Genius! Was looking for a project for Christmas!

Let me know when you have the 3D files ready!

Yes, mainly for priming, but pump angle, also seems to act as flow switch.

I would call it a sYphon priming pump, pronounced sigh-phon. And pronounce siphon, as sip-hon.

That will be really slow and painful.

My head comes with a free syphon starter.

Why do you say that? Looks pretty simple and quick from the video

Get a drill attachment to it...
We got some peristaltic pumps in work...cost thousands!

They are designed for a completely different purpose which doesn't enable syphon flow.
This does not start and stop a syphon flow. It's designed to be accurate not quick.

I have tried and own many pumps for this hobby, from 2inch downwards.
A pumped syphon is a brilliant time saving thing, typically a 12v whale Sub or inline pump awesome.

These have no place.

Watching the video on the Etsy site, the pump is used to draw sufficient wort from the kettle to prime the syphon. The front cover can be rotated 180 degrees and releases a flap at the top of the pump body and in doing so releases the “squash” on the tubing allowing the liquid to flow freely. Neat idea. Probably the feature that has a patent pending as peristaltic pumps have been around for years.

 

[Agentgonzo]

Yes, it's a nice little design. You can also rotate the pump a bit so that it continues to squash the tube, which well then block the flow and stop your siphon (and then act like a normal peristaltic pump). Very clever. Far cleverer than the comments on here that don't understand how this particular variant works.

 

[peterpiper]

Nice thing, is that it's only a silicone hose to clean and sterilise.
While other pumps, aĺl a pain to keep clean.

I'd rather spend 30seconds priming, than hours extra, sterilising.

After a few days of over-complicated (did I just say that?) thinking I hit on a non-rotary approach but using the same principle. The Buffers brewery Syphon Mangle . Needs a bit more work to make it easier to use but that's a project for after Boxing day.

Nice! I love the ingenuity!

Thanks for the 'pinch' syphon suggestion. That looks much easier than operating a rotary pump.

Thinking: some snap on system, that would allow it to be started at top rather than pushed up pipe, might ge a game changer. And rotating pinch points, would make it less effort.
But that's maybe, also, over thinking things. As a (fixed) rotary pinch mechanism, would probably easily cross from pipe edge, to centre, as you started it.

Christmas festivities are now over. Apart from transferring my latest brew from fermenter to pb this is my next project. Having established the Mangle method works it's about how easy it is to position. I'll let you know how I get on

 

[MashBag]

It sucks.
