How best to transfer 2 liters of liquid from one container to another and back again? Answered

I'm bulding a cleaning machine.
I need to transfer 2 liters (.53 Gal) of liquid (water with a small amount of cleaning agent) from one container through a filter to another empty container of the same size, quickly.
I would like to accomplish this buy pressing a button.
Then transfer the liquid back to the original container.
Looking suggestions on how best to accomplish this.
Thanks

On of the poping noises you that can be heard when playing a vinyl record is a tiny dust particle wedged in a record grove and held in by a static charge... There are brushes that have an alpha particle emitter source that ionizes and discharges any static charge permitting the bristles to dislodge micro particles lodged in the record grooves..

I the old days we could buy tiny snap on devices to the record pickup arm and clear every record that was played.

Today you would have to hack a smoke detector for the Americium micro-curie and mount it to your needle..

And you need two topics for this - why?

In that case it depends on the filter and amount of contaminent we don't know about.

It's for an ultrasonic record cleaner. The idea is to rotate an LP record slowly through an ultrasonic bath of about 2L of cleaning agent. Then pump out the liquid to another container so the record can be dried in place. As for the filter, I haven't decided yet. I'm thinking about using a 5 micron stainless screen.

FYI - I deleted the second topic.

I know from experience that the paper labels on the vinyl does not like it too much getting wet.
So you should keep the wet times as short as possible.
A simpler way to deal with all might be to include a tap on the bucket to drain the water through a filter.
Takes only a gravity and with the dust from a LP there should be no problem filtering it on the way, even through a coffee filter.

yes, paper record labels + liquid = BAD :)

I plan to place the record vertically in the bath with only enough of the record submerged to cover the grooves, then rotate the record slowly.

I agree it would be simpler to drain the water manually, but the geek in me wants to automate the process as much as possible.

turning very slowly is one option. Very fast so centripetal F slings fluid off is another.

Thanks for the reply Toga_Dan. I'm actually thinking of using a vacuum pump to vacuum the record and remove any contaminants left on the records surface.

This was my first time posting here. I didn't realize there was such a long wait before a question is posted. I thought there was an issue with the first post so I posted again.

An RV pump 12V or 120V

will do that for you, and these pumps are used in cleaning machines.

A solenoid and some one way valves should let you use only one pump both ways.
