how much time it's good until need replacement ?

Mine lasted 18 months. Considering it was a replacement for a different tank that lasted 5 years, I consider that pretty poor.

How much pressure is in it when received?

It comes with the proper pressure. Over time, the pressure will get too low. Go on YouTube to For instructions on how to re-pressurize.

What's the recommended pressure to keep on the bladder? 8psi?

Pre-charge with 5-7 psi of air pressure. When tank is full it may reach 45 to 50 psi of pressure depending on your RO system.
