VEVOR Spindle Motor 2.2KW 80MM Water spindle motor 220V Cooled Spindle Motor ER11 Collect (2.2kw)

Does this require a VFD.

Size of collet on 2.2kw water cooled spindle motor. Needs to be ER20

What water pump can be used with this spindle?

Please confirm that it has ER20 collect holder - not ER11. ER 11 is no good for my use.

What Collet does this product come with? As it says ER11 in the title but says ER20 in the description and in the computer rendered images.
