I don't have much luck with my triac, the coolant pump is on its way out.
is there a suitable replacement that I can just drop in?
anyone got any info or links?

Does it give poor pressure.
try taking the plastic pump apart and re-flatten the surfaces, they can leak through the casing giving poor pressure.
I've repaired one before using this method, and it works well.

no, the pump wasn't doing anything. so unbolted it and the main spindle was jammed, when I turned it, it made a grinding noise. it now works but is louder than the machine its self
CNC Expert
is there a direct replacement for the entire pump?
rather than faff around with bearings I might as well replace the 15 year old pump

just a guess on the price, but the problem you're going to have is getting one the correct depth.
CNC Guru
you'll get there mate. The bearings are really cheap and easy to replace.

I got one from them for my Triac PC, if memory serves me right I got the 130mm one and had to just pack it up with a piece of 1/4 inch thick alu plate, has worked fine ever since
Anyway, just measure the one you have and get the one that`s nearest

I think the original pumps were 5" = 127mm, (Only a guess! !) the 130mm one clears by a few mm with the 1/4 alu plate I fitted, was just some material I had at the time

the pump completely died, so I had to take it out either way. thought it take it to bits and have a look, think I found the problem
turns out there is a little plastic cap on top of the coolant pump that just sits there letter coolant into the hole, good work denford

in fairness to Denford I have had to replace bearings in industrial coolant pumps with exactly the same fault.
