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.

Right, that does make it a bit more tricky. Is there any serial number or manufacturer?

I found something similar. I tried searching with the serial number but nothing came up.
