Anyone used a IPF4 interpet power head?

[Jay1]

I was looking for something and found something else!
A IPF4 my old man used back in 95" I think guessing this as the stamp is 1995.
I've tried running it and it runs perfect!
Even has the original filter foam housing that screws underneath.
What I wanted to know was the flow rate as Interpet don't make these anymore, but they were not cheap back in the day apparently?
I'm guessing it will be about 500-600LPH its only 12watts.
What I thought about was to stick a 14mm ID, 600mm long length clear tube, to make it into a spray bar?
Its got an airator for a air line, but can't see any issues re-using it as a extra flow pump for the tank?
Is it worth re-commisioning it up?

Cheap enough as an extra source of flow could make the holes bigger as the pressure is greater than flow I can tell as the air rator hole is gushing water from the top as air is usually sucked so room for improvement on the hole side. I'll drain a tank out for testing and see if the jets are big enough, but doing a bucket test the jet did flow about 2 foot or roughly a meter.
