A pressure exchanger for transferring pressure energy from a first fluid of a first fluid system to a second fluid of a second fluid system, comprising a liner (12) and two end covers (13 and 14 respectively) with an inlet and an outlet passage (24,29 and 26,23 respectively) for each fluid. A cylindrical rotor (11) which is provided in the liner (12) and which is arranged for rotation about its longitudinal axis, and which has a number of through-going channels with openings at each end arranged symmetrically about the longitudinal axis, where the rotor's channels are arranged for connection with the end covers' inlet and outlet passages in such a manner that during the rotor's rotation they alternately conduct fluid at high pressure and fluid at low pressure of the respective systems. The rotors' channel is characterised in that one end cover (13) is designed for outlet of ingoing fluid via a central through-bore (25) in the rotor (11) over to an opposite end cover (14) which is arranged for outlet (23) for the first fluid and inlet and outlet (24,29) for the second fluid.
