A multiflow pump for fluids, comprising:
- an electromagnetic translatory drive;
- a displacement piston unit;
- a pump head;
- and
- at least one outlet valve device;
- wherein the displacement piston unit contains a bearing journal with a spring receptacle, a carrier plate, and a plurality of pump pistons;
- wherein the displacement piston unit is configured in one piece;
- and
- wherein each pump piston of the plurality of pump pistons is provided with an elastomer seal which bears against an axial surface of each respective pump piston during a working stroke of the displacement piston unit, and in that each elastomer seal lifts off the respective axial surface of each respective pump piston during a return stroke of the displacement piston unit.
