How about this one: https://www.ebay.co.uk/itm/172219861161

Ah, ok thought was unusual for me to miss something obvious like that.!

Yep, that pump will be fine.

Regards the MCB then don't really need MCB but the suitable fuse is required to be safe but only in case of short it's not something you'll use has a switch.
The VFD Relay will handle this for you and because you'll only ever run the pump when the spindle is spinning you'll have no need to manual overide.

Thanks Dean - do you tend to screen your alarm signals between drives and IP-M?
