A high pressure press for treatment of substances such as food including a floating piston (10) in a pressure chamber with sealing means (11, 12). The floating piston (10) comprises drainage means for collecting any pressure fluid that leaks past a sealing means (11, 12) of the floating piston. The drainage means comprises a pressure reducer arranged inside said floating piston. The drainage means also comprises an elastometic pad which is so arranged as to supply an underpressure to a space (24) where pressure fluid leaking past a seal may collect. Collected pressure fluid is returned to the pressure chamber later in the cycle. The invention also relates to a method for operating a high pressure press and use of a high pressure press.
