Electrogenic ion transporter
Pump and transporter are synonymous: they refer to proteins that, unlike channels, use a form of active transport to move ions or molecules against their concentration gradient, although "pump" is most often used in the context of primary pumps, that is, those that directly use ATP, whereas "transporter" is more often used to describe the whole category or secondary pumps that use existing gradients.


  then also iam still confused why sodium potassium pump is in the category of ion transporter but not in ion pump


I have no idea where you are getting this statement from, clearly the sodium potassium pump is a pump.
