Yes you can fit a bigger pump however, you will need to check with Prochem to see if the heat exchange system will cope with the pressures that you want to use.
The reason for no pressure could be a number of things.  Is the pressure gauge reading any pressure?
Is there water in the header tank, is the pressure regulator stuck, is there a blockage in the pipe that feeds the pump, is there a burst pipe on the truckmount, are the jets blocked on your wand.
