A volumetric pump comprising a product metering chamber, a metering piston mounted inside the chamber so as to slide between top dead center and bottom dead center, a sleeve at least partially delimiting an intake chamber and an exhaust chamber for the product, and a product dispenser that is mounted so as to be able to move with respect to the sleeve and is able to place the metering chamber alternately into communication with the intake chamber and the exhaust chamber is provided. The pump also comprises a pressure sensor that is able to measure the pressure of the product inside the metering chamber, and a control unit that is connected to the pressure sensor and is able to verify the presence of pressure peaks exhibiting a value greater than or equal to a predetermined pressure threshold.

Positive-displacement piston pump and associated delivery control method

A volumetric pump comprising a product metering pistonmounted inside a metering chamberso as to slide, a sleeveat least partially delimiting an intake chamberand an exhaust chamberfor the product, and a product dispensing meansis provided. The dispensing means comprises an intake membercomprising product passage meansthat are able to at least partially face an inlet orificeof the metering chamber, and an exhaust membercomprising product passage meansthat are able to at least partially face an outlet orificeof said chamber. The intake and exhaust members are situated axially on either side of an internal partitionof the sleeve and are each mounted so as to bear axially against said partition.
