I have put two photos in my album showing a simple cooling system made for my bandsaw.
All you need is tank,can be an old saucepan,plastic box,paint drum ect
Pump from dead washing m/c+ supply tube from same m/c
Few standard pipe fittings.
Pump is fitted to base of tank,tube from pump outlet back up to play on sawblade. Oil flows from drip tray back to tank,which is mounted on bottom shelf of sawunit.
It,s simple,cheap,and it works.
It,s called "The Economy Model " Try it !
Pictures might not be too clear,but the idea is ;Drip tray over tank over pump,then outlet from pump back to top..
Pump is wired to saw switch,one on,both on.
A tank holding about 1 gallon is big enough for saw, for lathe use 2 gallons is better.

Just a small warning:- Be very sure that you have a filter and settlement tank before returning any steel contaminated coolant back into the tank. The little washing machine pumps have a permanent magnet rotor that is exposed to the liquid. If there are iron filings in the liquid they will soon stick to the rotor and stop it from rotating.
Discovered this when washing my overalls after getting cast iron dust in the turn-ups .
The rotors can be removed and wiped clean, but its a hassle if you have to drain the washing machine and turn it over to get at them...

I return the suds through a filtration sock thing. They make them for the keepers of Koi carp and sell them on flea bay. You can get them with a rigid plastic top. I 3D printed a fitting for mine to make it posh.

I filter my suds return with a gauze in the chip pan over the return well. I also have several strong magnets from PC hard drives in strategic points in the Boxford's built in tank. I get a very clean particle free fluid at the nozzle.
