No problem in code.
For the first time you are saving, it saves properly.
For the next time it throws exception for every new save you should refresh the page.
Beacuse the controller is retaining the old values.

PageReference pr = new PageReference('/apex/PageName');

pr.setRedirect(true);
        return pr;

 

Below one is to navigate that particular page.

PageReference pr = new PageReference('/apex/PageName');

 

Below is to refresh the page after the record is saved.

pr.setRedirect(true);

 

So that when you save it again it will not be treated as update and it will not give error.
