Does mini 12V DC diaphram water pumps like this get really hot after running for 5 min? (sh.itjust.works)

I'm trying to use it as a water pump for my aquarium. I'm using a 6V 4.5AH battery with a DC step up convertor to power the pump. After about 5 minutes it gets really hot. Is this expected?

Actually I tried searching for it, but could not find the datasheet for it. This was given to me by a friend. I believe he bought it from AliExpress. As for current, I'll, measure it and let you know in a few days, I'm traveling right now.

I found a similar product with some number on its side. But so far nothing is coming up. I'll keep searching.
