Can I have "pressure waves" phenomen with a liquid fluid with mach number less of 0.3?

Yes, you can have pressure waves in liquid even at Mach = 0. In a long, lets say 15 km pipe having rigid wall, filled with still water any pressure disturbance at one end will need approximately 15 seconds to reach the other end of the pipe.

For a long look at the theoretical dicussion of this phenomenon, take a look at the thread regarding 'shock waves/bumps in viscous flows'.
