Pump for pumping water from a small and medium depth, characterised in that it comprises a tubular body containing a piston 10 returned by a spring 9 whose displacement is ensured by the water contained in a chamber 8b; the piston displaced by a piston 10 forces the water lifted at 11 through the valve 14 and forces it into the tube 6 and the outlet orifice 7 through a valve 17. <IMAGE>
