  • Dosing pump
    Patent number: 4515537
    Abstract: A dosing pump (1) is produced, with which a precise dosing is possible as a function of the time or of a flow rate. The dosing pump (1) operates with a preliminary transport obtained by means of a diaphragm (11). The stroke volume of the diaphragm (11) is greater than the volume of the pipe element present between a preliminary transport chamber (9) and a dosed medium tank (16). It is thereby made possible to omit a return pipe and a suction valve and a pressure valve.
