Italian to English Medical Medical: Instruments

Hello,

I am translating an inventory list of various medical devices and I am struggling with the term 'Saracina'.

It appears under the list of devices for water treatment:

'Saracina per prelievo acque di lavaggio trattate'

I have found 'Saracen' which is a brand name for water treatment parts but I would have thought that if this was the brand name then it would be the same as in English?

I'm a bit stuck and would be grateful for any help.
