Okay, here’s my experience with a manual drum pump for hydrochloric acid, written in a casual, blog-like style:

So, I needed to transfer some hydrochloric acid the other day. Not something I do every day, mind you, but when you gotta do it, you gotta do it right. I didn’t want to just pour it – too risky, too messy. I decided to get my hands on a manual drum pump, specifically one designed for, well, nasty stuff like hydrochloric acid.
Finding the Right Pump
First things first, I had to find a pump that wouldn’t just melt or corrode the second the acid touched it. No point in buying something that’d be useless after one use, right? I did some digging and found a few options. Make sure that it’s built to withstand the acid.
I Got one and assembled * was pretty straightforward.
The Pumping Process
With the pump is set up and then i started doing the pumping action.
It creates a vacuum, pulling the acid up through the tube and into my receiving container. Slow and steady, that’s the key. You don’t want to go crazy fast and risk splashing or anything.
The acid started flowing, nice and controlled. It took a little bit of elbow grease, but hey, it’s a manual pump – what did I expect? It was definitely better than trying to lift and pour the whole drum.
Clean Up
After I got all the acid I needed transferred, I carefully rinsed out the pump with plenty of water.I let it air dry completely. This is important, and making sure I store them separately, the pump and other tools used.
The Result
In the end, the manual drum pump worked like a charm. Transferred the acid safely, no spills, no mess. I can be sure to do the job safely.

If you’re ever in a situation where you need to move hydrochloric acid, or any other harsh chemical, from a drum, I definitely recommend getting the right kind of manual pump. It’s a simple tool, but it makes a world of difference.
