Teardown of a two speed aquarium pump

There are two interesting things about this pump. The case is transparent, so you can see what's inside - which is nice, and there's a switch on the side that lets you choose two power settings.

This is just a quick video taking the whole darn thing apart to see how they select the speeds and the general construction. (very classic aquarium pump design)

Not sure the actual air volume or pressure of this unit. The listings are always a bit generous in their ratings. At this point in time I've not been able to find the listing I got this from.

It could perhaps benefit from a few strategically placed blue neon lamps held securely in place to avoid vibration issues.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
