Modular pump system

A modular pump system having a plurality of electromagnetically actuated reciprocating pump configurations, comprising:

• the plurality of configurations of the reciprocating pump having a magnetic part and a pump part selected from at least three different pump parts that is predominantly arranged in an interior of the magnetic part, each pump part connected to the magnetic port by way of a connecting site on the magnetic part, and a cover;
• the magnetic part having a magnetic coil, a magnetic flux-conducting support and a brace;
• each pump part having a pole including a control cone, a pole pipe, an armature, a cylinder and a displacement piston that is pushed or pulled in a longitudinal direction by the armature, said displacement piston being returned into the respective other longitudinal direction by a resilient element, if the armature is not energized;
• wherein reciprocating movement of the armature is caused by a linked magnetic flux that is generated by the magnetic coil and is guided by the support, the brace, the pole pipe, the armature, and the pole;
• wherein the magnetic part is an assembly that can be pre-assembled and can be tested, said assembly being provided with a synthetic material injection molding;
• wherein the connecting site on the magnetic part to each pump part includes a connecting contour that is identical for each pump part, and it is possible using said connecting contour to push each pump part of the modular system into the magnetic part to form each of the plurality of different configurations;
• wherein each pump part is an assembly that can be pre-assembled and can be tested at least with regard to its displacement volume;
• wherein the magnetic part in the case of all reciprocating pumps of the modular pump system includes identical or geometrically similar connecting surfaces, for receiving the magnetic part in a holding device.
