Don't know what a roller pump is..but we used to put 225psi 10 stage pumps on all the time with no issues on higher end equipment like that. Loc line is the only thing that didn't like it

I have a Matsuura MC-600VF that I'm running mineral oil based flood coolant. The machine is in my garage and I don't want to deal with a water based emulsion right now. The machine's centrifugal pump couldn't make enough pressure to clear the chips and I get a lot of smoke when facing and using my 1-1/2" mill. Tonight I installed a 6 roller, roller pump with a 2hp 3ph motor driving it. I don't know what it's making but it can make up to 300psi. The hose on the machine is rated for 500psi. The spray nozzles are mounted in a stainless ring. It all looks really stout, but I don't know if it might cause problems. I couldn't find anything in the manuals other than an option for 300 psi through spindle. What do you guys think?

Roller pumps are similar to rotary vane but use rollers. I think this reduces friction and makes them more tolerant of particulates. The one I have is a 6 roller. I got it from Tractor Supply for $106. Rebuild kits are $45. They are usually PTO driven for spraying chemicals. I was surprised the electric motor could turn it with the oil. I bought a bypass regulator today so I can have some control and I'm going to add a gauge.
Here's the manual. It includes reversing and rebuilding instructions, and flow/pressure/hp charts.
