Some time ago i came across a video or an article on the world wide web that consisted of a syphon/pump for a drum or a barrel. It used an air compressor to introduce air into the drum and then the contents were forced out of a tube, lift tube like. I cannot find this information. Ive searched and searched all over and i cannot find the DIY instructions or the plans on how to do it. Do any of you know what i may be talking about? What i have found is.. The manual pump style syphon/pumps which are constructed from PVC. Thats not what im after.. Can any of ya help? Or maybe one of you have come up with what im trying to describe. Thanks
THIS! This isnt the video but this is exactly what i am after. Now to just figure out the fittings to connect the lift pipe to the drum..
We used to pump drums with air all the time at my dad's chemical machining plant all the time just made a dip tube that screwed into the 2 inch hole with a 3/4 hose coupling on the top and took a pipe bushing on the small side with a quick coupler to hook to the air supply with a valve to turn off the air the air hose we used had a regulator set to 5 psi and it worked like a charm we had to pump mineral spirits into a tank 3 times a week from drums we settled on 5 psi did not distort drums we also had the same kind of setup to pump acid from plastic drums into etching machines you just have to watch pressure careful with plastic drums and we also used a 1 inch hose for the acid JB
Im doing it in 1/2" I didnt know that the bungs on the drums were just normal pipe thread. So i have the adapter, bushing from 2" down to 1/2" and 1/2" pvc pipe. Tomorrow im going to pick up a few elbows and miscellaneous other fittings and ill be done with it.
I forgot to ask what you were pumping thin liquids Gas,Diesel,fuel oil etc pump easy watch your pressure when doing oil or other heavier fluid . some plastic drums have a different thread it is coarse but the caps usually have a pipe thread in the center of the bung JB
