For security purpose, hash is mandatory.Whenever you talk to PayU server you need a hash.For every API there is a separate hash because all API are public.
It is MANDATORY to calculate reverse hash on your surl/furl to validate a transaction at your end. Otherwise, the transaction maybe hacked or tempered with.
For more info, please refer for more details.

Yes, merchant can also generate hash from PayU SDK but it's not recommendable because in this case key and salt will be hard coded so any body can use key and salt for making payment and it's not secure.

The merchant can check if he is calculating hash correctly by entering the same parameters in above tool and then test the hashes generated with the hashes he is getting from his code.
When the transaction successes then the PayU posts the response to the Surl and if transaction get fail the PayU posts the response to the Furl provided in post params while making payment request.
PayU page will not get expire, however, the PayU id generated will get expired or bounced if customer doesn't do anything after landing on the payment page for 3 hours. Also, if after 3 hours if customer enters the card details, new PayUid will get generated and transaction will go through.
