Hi guys - looking for some advice on where to get a reasonable size coolant pump for my mill. I have a fully enclosed (on the sides and bottom anyway) MD-001 (its a big ZX45 - same as IH mill).

I currently have a little diagphram pump that is rated 1 GPM @ 0 psi and must be much less at its max of 60 psi. It just isn't doing the job of flushing the chips out of the pockets.

Anybody have a source for a pump in the 3 to 6 GPM range (180 to 360 GPH) with a reasonable pressure output (need to pump 6ft of head to get to the quill) for single phase power (120 or 240 VAC ok)?

I found an ebay seller of these pumps but I emailed him and he only has 3 phase motors :violin: Filterable Coolant Pump 1/8HP 180mm 3PH 220/380/460V | eBay

I suppose if I have to I can buy a cheap VFD to drive it but that seems like overkill...

Anyways...I wait for a flood of responses

Mike
