Abstract (en)

[origin: CA3084583A1] Crinkle diaphragm pump (1) comprising: a body (2) inside which there is an internal chamber (2a) comprising an inlet opening and an outlet opening for fluid (22); a flexible diaphragm (3) placed inside the chamber in which it can crinkle. The pump further comprises: an actuating mechanism (4) comprising at least one motor (M) and a mechanical connection piece (41) connecting the motor (M) to the first edge of the diaphragm (31) in order to move it in a reciprocating motion. The pump also comprises a detection device (5) for detecting at least one value indicative of a movement of the diaphragm (3), a power supply unit delivering an electric power supply signal to the motor on the basis of a detection signal (Sd).
