Manual pump?

Was just curious if someone makes a rotary style transfer pump that would be food safe (for brewing of course) that is manually operated instead of electric motor?

I have been doing some searching around the web and see nothing that fits this bill, just trying to see if anyone knows of any or has better google-fu than I.

Google diy peristaltic pump. If you're handy you can make one with stuff you might already have around the house and/or a few bucks.

FYI: I'm a big DIY person and after I built something "acceptable" for small batches, I still ended up buying some pumps, a few cheap and one march pump. Check this thread if you decide to go the cheap route https://www.homebrewtalk.com/f11/cheap-pump-fda-approved-12v-100c-337933/

Those things spin pretty fast- you'd have to be doing a ton of cranking for a very long time to get any significant flow. Why would you want a manual one?

Seems to me if it were a manual pump it would be gear driven to compensate for the high rpm needed so a person didn't wear out their arm spinning it up, this is assuming it is designed to be used as a manual pump.

Even if it was still high geared it wouldn't be all that difficult to gear it down through various means to get a comfortable spin pace to keep rpms up for desired transfer rate.

Why? No real reason just curious if anyone builds one or has experience with one and with a 5-10 gallon system it would be a simple option IMO.

You could probably hook up a DIY peristaltic pump to a bike wheel. Make your friends pedal for their beer.

While you're at it, make them pedal to crush the grain too.

Well some people manually crank crush their grains so why not?

I agree, make them work for your delicious homemade brew
