What type of pump is this?

I don't understand this setup, seems to be a DC pump, but the outlet and inlet (if that's correct) are connected to each other? And then going to the fill pipe for the water tank. [Hopefully two pics attached].

Any chance this is an air compressor instead? If so, how does that actually work?

Thanks!

It really looks like an air compressor with the Tee connected to a pressure switch. There was a time when the fresh water tank was pressurized to provide flow at the tap. Have to assume the way it worked was after the tank was filled, the inlet valve was closed and the compressor was switched on to maintain a pressurized system.

Definitely an air compressor.

Many thanks everybody.

Yep.

Pressurized tank fresh water system.

Fill the tank with water, then compressor them kept the tank and plumbing pressurized to push water to the faucets.

The system of choice before modern water pumps were as reliable as they are today.

I have something similar in my trailer, my question is can it be replaced with a regular water pump?

Yes, just use the pipe from the bottom of the tank and run it to the inlet of the new pump. Connect the other end to the pump outlet, connect the power and you will be good to go. It is a simple conversion.
