Of course the pump power requirements will be variable. The exact power requirement will depend on the flow rate, the pressure and the mechanical efficiency of the pump. Operating close to one end of the pump's performance curve will cause the pump to draw less power... it's peak consumption is typically near its peak efficiency.
