Amarine Made Barrel Pump Plastic Polypropylene Hand Rotary Transfer Drum Pump 300cc(300ml), 70 times/min

The threaded component of the pump does not match / fit the thread count of the barrel. Therefore, pump is unstable and difficult at best to operate.

We used to it pump gas and it stopped working after just 1.5 months. the feeder hose bent and the pump would not pump a drop.

Great value,work excellent for antifreeze and windshield washer fluid

Works until the internal guts go bad. I wish they lasted longer, but it does work.

I purchased this pump twice within a week. The first time, I assumed I had assembled it incorrectly because it seemed like a part was missing—specifically one that would secure the hand crank mechanism. However, when the second unit arrived, it contained the exact same parts. I followed the video instructions on the website and even had a family member double-check the assembly, but the pump was still completely nonfunctional. I did not attempt to assemble it a second time once I saw the 2nd box had the same contents. It just confirmed that nothing was missing from the first package—the product itself appears to be poorly designed. Despite the positive reviews, my experience with this item was not satisfactory.

The parts inside rusted because we were trying to use dish soap in it.

**UPDATE** Seller let me know that the threads match an IRON barrel. Ours are plastic. They offered a few good solutions. Upgrading to 4 stars. Will upgrade to 5 stars if they mention in the product description that this fits standard iron barrels only. As a previous review stated, the threads of the insert don't match the barrel, which makes the pump pretty difficult to use. I'm not sure if it's just some types of barrels, but we use fairly standard car wash chemicals and all of our barrels are the same. Also, all other pumps fit our barrels fine. Would love to hear from the seller to see if there's another part that could be sent out. Otherwise I guess I'll be duct taping it. The pump works well aside from how it fits on the barrel.

This pump is a great value and works fabulously. We use it to pump alcohol, ferric chloride and chroming chemicals.
