Transfer Pump Ruined My New Drum

Has anyone ever had this happen to them? I just got these new used barrels (had motor oil in them) and installed a brand new Fill-rite FR-112 rotary pump. I cracked the small vent plug on the drum but I guess that wasnt enough? You can see the other drum there and its our old pump on it. That pump was installed on an old drum we have and had it for about 30 years with no issues like that. I dont like keeping that vent open in fear of getting trash and water in. Do you think these drums are made with thinner material now?? What would be a good solution so this doesnt happen again? I can get another drum.

Make a 180 breather stand pipe in place of the vent plug. A 3/4" NPT x 4" nipple, 3/4 street elbow, 3/4 elbow, and a 3/4 NPT sintered bronze breather vent (180 allows it to be pointed down).

Yes I was thinking of doing an elbow vent out of pipe. Didnt know how to keep bugs and trash out though. Thought about some type of check valve type thing
 
Natural gas company has a yard near the house. During the Summer the drums of different chemicals does that. At night you can hear the drums contracting and all during the day they expand.

If the vent plug has a flat bottom. You can drill them and install a valve stem. Remove the core. Place a piece of fuel tube long enough to hang over the edge of the drum and then install a small engine inline fuel filter on the end of the hose. It allows the drum to vent and the filter keeps dirt and water from entering.
 
The do vary in strength.
16, 18, 20, 22ga
No ribs, two ribs, three ribs
About a dozen different UN ratings one of which is test pressures ranging from 100 to 300 psi.

I guess you now know your pump is not worn out.

sintered bronze breather fitting pointing down will do it.

Marine Fuel tank vents come in a vast variety of configurations, some are surge proof and restrict fuel from getting out, but vent inward, as well as
keeping liquid (water) from getting in when placed above the barrel rim. All have screens that are approved for flash suppression. Cheap as well. A
barbed hose fitting a 2" piece of quality neoprene hose, and the boat vent. My suggestion. I googled - Marine fuel tank vent. Jim
 
Remove the pump. Install a tire valve right beside the opening to the drum, you'll have to drill a hole. Put air to the drum untill it pops
back in shape. Then as other s have said vent it with a 90* + 90* so no water can enter.
 
Impressive what 14 psi will do. Yes drums are thinner today. .

We get metal delivered in them and some of the drums are so thin they collapse when we pick them up from the outside
with a forklift and barrel lifter.
 
Dad worked for a company that manufactures small vacuum pumps, air motors, blowers and compressors. For the annual company picnic, his test lab would create a guessing game for employees to win prizes centered around a product they manufactured. One year they set up a tiny vacuum pump on a sealed 55 gallon drum during the Owner's usual lunch-time speech.The employees had the opportunity to enter a guess how long before the drum collapsed from the pump action. Man, when that thing imploded, it was impressive! This was early 1970's, so drums may have been more robust, but a sudden crumpling accompanied by a huge noise got everyones' attention, and ended the speech short, a welcome side benefit!
 
Not all drums are created equal. Some are heavier than others. Depends on what you buy them for.

Regarding your implosion, the cylinder of a drum is very strong. A dent though, compromises that cylinder and will
lead to an earlier vacuum failure.

Drums are not meant for any pressure or vacuum storage.

Several times now, purely for entertainment, I loosely put a steam hose in an empty drum (not pressurized). Get her
good & hot, pull the hose and quickly replace & tighten the bungs. After the steam cools, it pulls a vacuum. Once
the drum goes, it is very sudden. Just don't be handling the drum and get your finger caught in a crinkle!
 

RTR, that is not very wise to post a picture on the 'net showing all your treasures in the background. You better get a mean junkyard dog if you don't have on yet.
 
That reminds me of an Uncle's tale: When he was in the Army, one of his duties was to guard the fuel dump at night. He went one way around
the facility, another guard went the other way. Back and forth, all night long. They had just got within sight of each other at the back
when a drum mad a big pop.
I guess he/they thought it was going to blow up.
He said he was about 1/4 mile away before he realized he no longer had his rifle. He threw it down so he could run faster. And the other guy
didn't have his rifle either. So no one told on him.
 
Back in the late 60's-early 70's ,I worked at an Owins-corning fiberglass plant. They made huge underground storage tanks for fuel and whatever. Well they had a test room shutoff from rest of plant. They put in a few pounds of pressure and checked for leaks with soapy water, also had to hold for a time. If ok they then pulled a vacuum to test strength. A long came I with a light fixture to hang in the operator's room, well just say the 6000 gallon tank failed!! The biggest darn Implosion I ever heard!! The good old days at work. joe
 
I have seen 10000 gallon stainless steel vessels suck right in from being filled with steam and cooled too fast without adequate venting. Some of them were even charged with compressed air, but it could not keep up with the contraction.

Water expands 1600 times it's volume when it changes phase to steam, and contracts likewise when condensed back to water. In a steam power plant, the post-turbine condensers will stand at 27-28 inches of vacuum depending on the temperature of the cooling media.

Just stuff some Scotch Brite, coarse steel wool or something similar in there. My fathers home built air compressor had a steel wool air filter (home made) that got a shot of oil every now and then. Ran for decades that way.
