In my opinion making one yourself is the way to go! :D Much funnier and more educational! I would suggest making a impeller pump and then attaching some kind of filter. try googling for impeller pumps or sending me an email, i think i have the drawings for one stille lying around. |

So, I have a question. I would like to use a coolant on my mill (and perhaps my lathe). Used a mist cooler over the years, but don't like the noise associated with running my very large, old compressor. Are any of you running a coolant mixture (rather than just water)? I have some concern about running a mixture that contains some petroleum base against a plastic or rubber diaphragm in the pump. Water pumps in a car for example use an elastomer that contains fluoride to prevent hardening and eventual cracking. -Dick (former plastics chemist long ago) |

coolant pumps are about £100..... one off, sorted, know it works every time, is it worth the effort? |

I used wash machine purge pump (the one that pumps used water into sewer...) it worked, but I gave up on this one. * My first coolant system I didn't realize plumming was that important. Tray was way too big (it still is) not enough list -> needs a large volume of coolant * This motor was split phase = cheap to mfg. but can be used only intermitent duty = fine for saw with my use, but not much use on lathe or milling machine. * Resorted to a total loss system with only manual dripfeed = fine for band saw and I only mix 0.5 litres of coolant at a time. Now....I have a resipocating pump from espressomachine. It says 15 bars max. pressure and a little volume. Wish I would know if seals would take any cutting oil or coolant. I'm thinking of trough cooled small drills :scratch: Pekka |
