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?

There are a lot of fast moving part with variable pressures and friction all around. All these things create heat.
