Tanque de repuesto para bomba de presión Pascali

The tank as received was in perfect shape, nou dents or even scratches, which is a good thing, becuase to judge by the weight, the pressure shell and the brackets must be made from metallized paint. Can the shell safely hold the pressure set on the switch controlling cutoff on the matching 370 W pump?
What is the MAWP? There is not a stamped plate on the tank, nor any accompanying documentation, never mind certificate of test in kiloPascalis.
The bladder is hugely crumpled, but shows no cuts, tears or pinholes at zero bar flll-up.
Not keen to install the tank above my ceiling. What advice?
Pascali is in Italy, or China?

Product does the job as advertised. Was easy to install and set up.
