Abstract (en)
A volumetric pump (1) comprises a chamber (2) divided into a main sub-chamber (21) and a secondary sub-chamber (22) by a first diaphragm (5) which is clamped in the chamber (2). An inlet port (23) and an outlet port (24) are located in the main sub-chamber (21), and a compensation port (26) is located in the secondary sub-chamber (22). A linear actuator (6) is configured to cause a reciprocating movement in the first diaphragm (5), thus causing a variation in the volume of the main sub-chamber (21). The pump (1) also comprises a by-pass channel connecting a compensation port (26) located in the secondary sub-chamber (22) with the inlet port (23) of the main sub-chamber (21).
