Review on Genuine Hyundai 25100 23022 Coolant Assembly by Andrew Agarwal

OEM is what you need for this item. In the aftermarket, not even Gates has three correct pulley flanges. The original has a lip which is very helpful when installing the pulleys and milling the bolt holes. I have 142k on the original pump and the bearing still felt smooth, but being in the timing belt business I might as well replace the coolant pump if it ever comes up. I'm sure the Gates pump that comes with their TCKWP284 is a good pump, but the flange is just round and doesn't have a mounting tab. I use Gates TCK284 because they are the OEM supplier for belts, tensioners and tensioners.
