Pressure ratio doesn't have anything to do with thrust - you could have the same pressure ratio on a 22 lb thrust turbine and a 22000 lb thrust turbine. A modern, single stage centrifugal compressor in this size range should be running a
PR around 5 or 6. Meaning that the CDP would be around 5 or 6 bar. For reference the original Whittle turbojets were around 4.6, the JT8D was around 16 and the latest generation turbofans are around 40.
