Rigging a new coolant pump

[gearhead]

My flood coolant pump went out in my WS #3. Thinking about using a small pond pump or fish tank pump to push the coolant. I had a very used fish tank pump rigged into the system and it seemed to work well for a very short time. The pump shot craps, what I dont know is if the pump was just weak or the pressure from running all that coolant burned it out. I'm concerned that when I close the coolant valve to remove parts from the chuck that the back pressure will kill any pump I put on the machine. Any thoughts or ideas...

A little giant submersible pump is the ticket.

we have used them around the shop for years. They make a few types but they do make ones for use as a coolant pump.

I would look into a "Little Giant" submersible pump. You can drop it right into your tank, they are fairly cheap and they are made to do what you want to use it for.

I put a Little Giant in my #3 16 years ago. The only problem is getting it out the little hole in the pan to clean the sump. IIRC it's the larger capacity size, but a smaller capacity will work just fine.

Just ordered a Little Giant should be coming to the shop by thursday. Does anyone still make the movable coolant pipe elbows. These elbows allow the coolant pipes to be repositioned to the work being turned. I have a couple that leak and thought about replacing them. How difficult are they to rebuild.

Gearhead...I always put a tap right above my pump to allow pressure relief in case I need to shut the coolant off at the machine. It works very well.
I have a Little Giant in my most used machine (bandsaw) but have a cheap parts washer pump in my system for my horizontal mill. Both work well. The parts washer pump cost half what the Little Giant cost. Won't last as long prolly.

I have been searching the web for the adjustable elbow replacement, but no luck. IF someone knows of a location that sells them let me know thanks...

Mcmaster Carr has them. But starting at 25 USD might be a bit high.
Search for swivel joints (or page 94)

Got to be cheaper somewhere different.
