Anyone know if a 110 volt pump similar to auto windsheild washer pump is avaliable,I am working on Drilling machine project and table has no coolant slots, so was wanting small volume pump for misting.

No help w/the pump, but have you considered air drive?

Nothing specific, but how about a modification to an airless paint sprayer?

Start with the misting nozzle. Its requirements will determine the pump necessary (psi, volume, etc.)

cheapy air brush gun HF about $5 need to do that myself. I used a chemical feed pump for years but finally died expensive but was free and can't replace.

Hi would one of those injection pumps to inject the base of buildings with fluid as a damproof membrane.They may also be called dcp injection pumps My son has two of them,could I use one for this also?Alistair

Try and get a Waterpik "dental cleaner." They have a small, adjustable stroke, positive displacement pump that will give the pressure needed for a mister nozzle. They show up at garage sales and "used stuff" stores and, since the unit never is/was actually in anyone's mouth, sanitation is not an issue.

Why not use a windshield washer pump and a stepdown transformer/rectifier? I did something similar as a coolant system for my lathe, see:

Thanks for all info , just starting to gather the goods for another project.

Think it might be a little overkill for a coolant mister.

Not for bill gates its not. For him that is even an underperformance product and a compromise. Why not have the best?

Just out of curiosity why do you need a pump if you are going to use a mist spray? Meaning I am assuming you will be using compressed air to atomize the coolant.

If you are going to use compressed air then you could either utilize a venturi effect or pressurize the tank slightly to deliver the coolant to the nozzle tip.

Have you considered a making a fogbuster?

I would like to pump coolant threw a fine nozzle:example(18ga. livestock needle without point) sorry for confusing this with misting.The Gang Drill project I am building ,table does not have coolant trough in it so that why am looking for low volume.

We just built one because we have flood coolant but it makes a big mess and mist fog is nasty. Our machinist wanted to use the flood coolant but now that he has seen it work he thinks we can do without it except for the very toughest jobs. I have one on my homebuilt CNC mill and just ran it steady for about 6 hours. Big pile of aluminum chips almost dry and no messe

When making yourself a misting unit for home use, compressed air plays a very large part in what it does.
Not only does it cool the piece parts, but also moves the chips away from the tooling cutting edges, then it lifts the liquid up to the nozzle for spraying.
If you are going to be trying to use a coolant pump to achieve the same results, all you will end up with is flood coolant, not a spraymist sytem.

This is how I made mine
