Abstract (en)
A membrane pump for suction and delivery of a fluid of interest comprising a head portion, a bottom portion, at least one side wall extending along a main axis A between the head and bottom portions, and at least one flexible membrane movable along a working direction substantially parallel to the main axis A to determine suction and delivery of the fluid of interest F. The pump further includes a fluid of interest delivery port configured to allow delivery of the fluid of interest, a fluid of interest suction port configured to receive fluid of interest on suction in a hydraulic circuit of the pump, and at least one intercepting element configured, during a pump operating condition, to selectively interdict and allow fluid communication between the suction port and said internal volume, and between the delivery port and the internal volume.
