Default piston pump

I've never seen one in person, but was fascinated by seeing them on YouTube. Wanted to know if anyone still uses this type of air pumps personally?

Default Piston Pumps

The last one I ever saw was the one I had on my big tank back in the 60s
It was a somewhat noisy thing and needed constant adjustment to keep it pumping properly
The piston was somewhat like a ticking windup namtle clock
The sound is intermittent so noticeable where a vibrator pump is more like white noise which is more easily tuned out
There was a pressure can between the pump and the gang valves so that the pressure was equalized across the pressure and recovery phases of the stroke and a check valves on both sides of the pressure can (belt and suspenders kinds guy) since the pump sat on the floor four feet or so below the water surface and I didn't want to risk the pump sucking water down on the recovery (but I never had much faith in those check valves with the springs in them)
I couldn't buy one when I set up my tank four or five years ago and wanted to make sure I had more than enough air

Times have shanged
That piston pump I said they don't make I bought when I set up my tank 4 or 5 years ago
It doesn't sound anything like the piston pumps of the days of yore
This is just a hum like a vibrator pump
If I hadn't seen it pictured in the F&S catalog I would still think I had a vibrator pump
It is the Coralife Super Luft pump
It is fairly large and heavy and puts out a lot of heat as well as a lot of air
It has been running constantly since I got it and has never given me any trouble
You probably don't want it in your livingroom but I sleep 5' from it
But then I live in a bell so it acts as white noise to lessen the intrusiveness of the never ending ringing
