The basics of pump installation When installing a pneumatic diaphragm pump, anyone who is not familiar with pumps and pump installations will often make small mistakes that result in costly damages. Here are some useful tips that will save you having to learn the hard way. 1) The diaphragm pump must be mounted onto a rigid baseplate. 2) The suction port size must never be reduced. 3) The suction pipe or hose must never be smaller than the suction port size. 4) The suction pipe or hose must be as short as possible and preferably never more than 5 meters 5) The discharge pipe can be reduced subject to design requirements within reason. 6) The pump must have a dedicated air filter/regulator installed. 7) The air pressure must be regulated to 29psi on the first startup, especially if the pump is fitted with TEFLON diaphragms. 8) A cycle speed of 60 to 70 cycles per minute is ideal for long life and a low cost of ownership.
Question on #5 why can't it be short as we want, I have a 250 gallon bulk tank for waste oil, and I'm literally mounting the exact pump in this video to the tank, so the discharge will be maybe 2 feet long, is that a problem?
I use a 1/2 inch diaphragm pump for waste oil. I have pumped 10k + gallons with it from 25 degrees to 120 degrees outside temp in Southern AZ, and hit pump with 100 psi instantly and let her go. It's been good to me going on 7 years and it lives outside on the ground or tossed on a barrel. I use 12' hydraulic hose from Tractor Supply for suction and discharge, works great.
Install a drain hose from your oil pan to a fabricated bracket to the frame rail , install hydraulic disconnects . Use single wire strand hydraulic hose .
Diaphragm pumps are fantastic pumps.. We used 1/2 inch, 1inch, and 1 1/2 inch.. You would have to see it to believe how much fluid the larger pump will move...
can't use it to pump anything flammable like gas or acetone due to static electricity could cause an explosion, and acetone would damage the rubber diaphragms anyway, but as for as fumes being in the room yeah no worries. This actually was cheaper than what a quality electric gear pump capable of pumping thick oil cost.
It sure slowed down when the oil entered the pump. Worked great . For the amount of oil you dump I wonder if you could burn it mixed with diesel in your heater.
I tried that once and it didn't do real well. I think if it was cleaned with a centrifuge and mixed at a real low mixture maybe 10% oil and 90% diesel it might work though
If it's the same truck you change oil in....A quick valve deal in place of the oil plug would be great with this pump..Just bypass the oil drain pan altogether..
I suppose you could do it that way. I'm a little leery of the oil change valves because I figure if you ran over something and it hit it that it could break off. So I prefer the plug. Just my thoughts.
yeah my previous method was something like that. I thought this method would be better and i can pump the oil back out of the drum as well if i wanted. I built a pipe with a screen on the bottom that would stick in the drum bung and connect to hose.
It should work on just about any size compressor. I have found out if you close the valve to where its almost closed and the pump pumps very slowly is the most efficient and uses not much air. The faster you want it to pump the more air it needs, but if you're not in a hurry it uses a lot less air with it pumping very slowly.
Next time, plug one of your outlet ports. 1in npt. Then regulate your air pressure to start at 40lbs, slowly open ball valve...i mean like 5lbs at a time, that way the pump primes properly, and works more efficiently. I cant even watch the rest of this...6 min in....yes, I am a hydraulic mechanic of 15 years
Figured out it's more efficient and uses way less air pumping slower, this video is from a long time ago. I just crack the ball valve maybe 1/4 if that seems to work well...
That's BS on the priming..Those pump aren't like gear or vane hydraulic pumps..Not gonna damage anything by not priming it..That's why it has a max psi because they know people are not gonna prime..
I'm not sure, but I've found that you can lower the amount of incoming air with a valve and it only slightly slows down the pumping speed. So it seems more efficient.

When installing a pneumatic diaphragm pump, anyone who is not familiar with pumps and pump installations will often make small mistakes that result in costly damages.
Here are some useful tips that will save you having to learn the hard way.
1) The diaphragm pump must be mounted onto a rigid baseplate.
2) The suction port size must never be reduced.
3) The suction pipe or hose must never be smaller than the suction port size.
4) The suction pipe or hose must be as short as possible and preferably never more than 5 meters
5) The discharge pipe can be reduced subject to design requirements within reason.
6) The pump must have a dedicated air filter/regulator installed.
7) The air pressure must be regulated to 29psi on the first startup, especially if the pump is fitted with TEFLON diaphragms.
8) A cycle speed of 60 to 70 cycles per minute is ideal for long life and a low cost of ownership.

@@rev9fan1 how did it work out for you?
@@rev9fan1 Reduced pipe size, not hose length.

Never seen an air powered pump before. Kind of pricey but explosion proof. I use 5 gal buckets but that works great in your application. Thanks, KIT d

Thank you, sir! Great info. I appreciate the time you gave. Trying to learn all I can about diaphragm pumps. This was a great start!
Oil is heavy and with those long hoses it did real good. Pretty cool.
yeah i thought it did pretty good considering how long i left the hoses. actually it pumped faster than i thought
oil weighs less than water.
really good but noisy pump.. also don't forget to use clean water to flush it.. get's clogged otherwise.
Nice demonstration appreciate all the info 👍👍
Many thanks for this demonstration.

What kind of compressor are you running with this set up ?
What are some others uses for the double diaphragm pump?
If it's the same truck you change oil in....A quick valve deal in place of the oil plug would be great with this pump..Just bypass the oil drain pan altogether..
I suppose you could do it that way. I'm a little leery of the oil change valves because I figure if you ran over something and it hit it that it could break off. So I prefer the plug. Just my thoughts.
Dang that's fancy. I dump my truck oil into a 15 gal rubbermaid container and scoop it into 5 gal buckets w an old water jug.
yeah my previous method was something like that. I thought this method would be better and i can pump the oil back out of the drum as well if i wanted. I built a pipe with a screen on the bottom that would stick in the drum bung and connect to hose.
chase5726 it's a great setup. I would totally copy u if I had a shop.
thanks!
Hi, could you tell me compressor specification for this pump can work?
It should work on just about any size compressor. I have found out if you close the valve to where its almost closed and the pump pumps very slowly is the most efficient and uses not much air. The faster you want it to pump the more air it needs, but if you're not in a hurry it uses a lot less air with it pumping very slowly.

Hi can i use 1" Pump to work with high viscous chili sauce?
@@hybrid4984 Hell yeah..That's what these type pumps are designed for..Thick slurry type stuff..
That's BS on the priming..Those pump aren't like gear or vane hydraulic pumps..Not gonna damage anything by not priming it..That's why it has a max psi because they know people are not gonna prime..
What is The amount of air needed to worke 2 hours without stop ?
I'm not sure, but I've found that you can lower the amount of incoming air with a valve and it only slightly slows down the pumping speed. So it seems more efficient.
Do you have someone who comes and gets the old oil out of your barrels? Nice little setup, Chase!
yes theres recycle companies that will pick it up
They picked it up at the bus shop too. Pennies on the gallon. Lol
That fitting on the end of the hose wasn't made in China was it ? lol
heck you know we don't make anything in the usa anymore! lol
chase5726 I know you're right about that lol
Nice job ! I find myself buying lots of tools lately, it's kind of addictive ;)
Never seen a pump like that good fyi
I used to work at a mill in maintenance and they had some 2" pumps like this to pump out spill containment areas.
Sir, may i know how last long this pump for that oil ?
thumbs up...
