Abstract (en)
A pump comprising a casing (100) which houses a piston (210) actuated in reciprocate displacement thanks to a coil (250) so as to successively suck liquid from a tank and expel such liquid to an output (14), in a pumping mode, characterized in that said casing (100) further includes on said output (14) a valve module (300) actuated by an auxiliary coil (350) so as to selectively reverse the way of liquid circulation into the casing.
