    So my Denford's little pump is struggling and I would like more pressure to 'wash away' the chips.

    Any thoughts on retrofitting something like this?

    It seems to give good pressure, see vid.

    I would look at the 'submersible' ones but I dont want to cut the coolant tank if they do not fit into the hole of the current pump. With the pump above I can simply run the inlet into the tank.

    If you have any chips in the liquid, then your pump will go dead within short time.

    For this are the normal centrifugal pump centrifugal pumps much better, because they have no problem with parts up to 1cm, sometimes more.

    Understood however the pump comes with a filter which should mitigate that issue.

    I also have dual 'grates' which catch the material and stops it from entering the coolant. Not perfect but the amount of crap that should be in the coolant is minimal.

    I recently purchased and fitted one of the 1/8 ph coolant pumps off ebay to my triac, very pleased with it and the power.

    Those are the ones, I can do you a vid over the weekend if you want.

    Can't remember what size but they do one thats a perfect fit length wise.

    As for power it's plenty of power for me, removes chips out the way nicely
