Abstract

A double-acting pump device includes a piston arrangement being slidably arranged in a pump housing. The pump housing is separated into a drive section with a drive fluid inlet and a drive fluid outlet and a pump section with an inlet and an outlet for a pump fluid. The drive section includes a switch mechanism which utilizes the difference between the drive fluid supply pressure and the drive fluid outlet pressure to reciprocate the piston arrangement, such that axially acting forces are transferred to the pump fluid which thereby achieves a desired pressure increase. Thus, the double-acting pump is arranged to utilize the energy in a supplied drive fluid to provide a defined pressure increase in a supplied pump fluid.
