Coolant Pump

[Earl]

I am looking for a source for a coolant pump for my lathe. I would like to build a muzzle flush system for my South Bend Heavy 10. There is a ton of info about muzzle flush systems on the net. There is even one article with a part number for a MSC motor / pump combination. That one is around 600 bucks! Since I will be using a water soluble coolant, I do not need a high pressure pump. I am thinking that a pump that moved 2 - 3 gpm with about 40 psi would do the trick. I spend several hours searching the net for one - no luck. Does anyone have any recommendations? I have looked at the Little Giant system and that may be a possibility. Does anyone have one?


Thanks,

Earl

You mite try looking at an electric fuel pump for automobils. The pressure and flow are around the specs you mentioned, and the lower price would more than justify a 12 volt electric supply.

Would a fountain pump work?

LMS sells application specific pump/tank units for $200-$250, pretty pricey though.

The Little Giant does seem like a good deal though.

Here's one from Enco on sale for $150.

I have two coolant pump/tanks, one came with my lathe & the other with the mill. I have no plans on using them yet but I'm not ready to sell. The Precision Matthews machines are fairly popular so you might be able to find some willing to sell their unit that they don't use. Maybe try posting a wanted ad?

This one looks interesting but it's rated at 80 gph at 2 psi - https://www.surpluscenter.com/item.asp?item=2-1224&catname=water Better yet, take a look at these waste oil transfer pumps - https://www.surpluscenter.com/sort.asp?catname=water&byKeyword=yes&search=waste oil transfer pump A little more expensive but maybe more appropriate? There are a number of other pumps to look through as well. Maybe you can find one suitable? (FYI - I have dealt with this company a number of times and so far have had a good experience.)

This is not a machine shop supplier, but I have bought a lot of equipment from this outfit. Back in the design/manufacture of water filtration equipment.

They have a large hard-cover catalog, but also online listings for their stock. Might find a pump suitable there. They have probably 100 different types and sizes.

There are some small pumps build for shower heaters under $100.00 they feature that you dont need to wire it to the machine, they will automatically start when you open the valve. They have sustancial flow.

Thank you all for your suggestions. I had previously looked at several of the suggested solutions prior to the original post. I have looked at most of the surplus outlets except for the one that Tony mentioned. I think that perhaps a fuel pump might be a solution if I can find a transformer to build a power supply with. I would like to keep the cost of the pump down below the $400 dollar mark.

Thanks again for all the help.

I have decided to go with a carbonator pump. I already have a half horse motor and coupling and the pump itself is less than 75 dollars. I talked to a fellow that has a flush system and that is what he used. Thanks again.

Sounds good Earl. I'd like to see a couple pictures of your setup when you get it together.

Thanks,

one point you guys are forgetting what is the coolant?

pumps made for water will not last pumping petroleum based coolants

A pump made to use with a parts washer will and can be set right inside the coolant storage tank/bucket

Adding a filter inline is a good idea external mounts used for cars are good for this as the filters are cheap and easy to get
it will help your CF last alot longer before needing to change it out
