1. A micro-dosing pump comprising:
a pump chamber substrate having a pump chamber;
a flexible membrane provided on a first side of the pump chamber substrate such that it covers the pump chamber in a fluid-tight manner;
at least one fluid line provided on a second side of the pump chamber substrate such that a fluid can enter and leave the pump chamber;

a permanently magnetized or magnetizable actuator disk coupled to the valve disk via at least one resiliently elastic element such that rotating the actuator disk rotates the valve disk, wherein the resiliently elastic element is configured to press the valve disk and the actuator disk away from each other; and
a drive unit having a magnetic pump plunger configured to move the membrane for suction or ejection of the fluid and configured to rotate the permanently magnetized or magnetizable actuator disk.
2. The micro-dosing pump as claimed in claim 1, wherein the drive unit has an electric motor.
3. The micro-dosing pump as claimed in claim 1, wherein the drive unit has a sensor which detects the stroke of the pump plunger.
4. The micro-dosing pump as claimed in claim 1, wherein:
the actuator disk has a recess in which a rod is provided, and
the rod has one of a magnetizable material and a permanent magnetization.
5. The micro-dosing pump as claimed in claim 1, wherein at least one of the valve disk, the resiliently elastic element, and the pump chamber substrate are made from a plastic.
6. The micro-dosing pump as claimed in claim 1, wherein at least one of the valve disk and the resiliently elastic element are micro-punched.
7. The micro-dosing pump as claimed in claim 1, wherein the fluid through-opening of the valve disk is shaped as one of an arc and a circle.
8. The micro-dosing pump as claimed in claim 1, wherein:
the drive unit is a durable unit, and
the pump chamber substrate, the membrane, the actuator disk and the valve disk are a disposable unit.
9. The micro-dosing pump as claimed in claim 1, wherein the resiliently elastic element is at least one of a beam spring, a plate spring and a spiral spring.
10. The micro-dosing pump as claimed in claim 1, wherein the membrane and the resiliently elastic element are formed in one piece.
11. The micro-dosing pump as claimed in claim 10, further comprising:
a mechanical coupling configured to transfer torque from the pump plunger to the actuator disk.
12. The micro-dosing pump as claimed in claim 1, wherein the membrane is made from one of a thermoplastic elastomer film and a structured thermoplastic.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of reducing or delaying damage to submerged structures due to adhesion and multiplication by harmful organisms living in the water in seawater or in industrial water systems, comprising the step of applying to the outside of the structure a biocide-free antifouling agent comprising fine basalt fibers or filaments, or comprising a combination of fine basalt fibers or filaments and E glass fibers, wherein the fine basalt fibers or filaments or E-glass fibers have a SiO2 rate of more than 50% by weight,
wherein the antifouling agent is applied in the form of a textile fabric selected from the group consisting of interlaid scrim, woven fabric, knitted fabrics or braiding, a fabric designed by the multiaxial technique, and a fleece,
wherein the exterior surface of the textile fabric to be in contact with the seawater or industrial water is formed predominantly by exposed free fine basalt fibers or filaments.
2. The method of claim 1, wherein the fabric is a fishing net which is placed on the substrate or on underwater surfaces.
3. The method of claim 2, wherein the fishing net is a knotless, warp-knitted fishing net suitable for aquaculture or an antifouling coating.
4. The method of claim 1, wherein the textile fabric is applied by means of adhesives or other chemically adhesive products to the substrate or to the underwater surface, or the textile fabric is applied to the substrate or to the underwater surface by sheathing with tightly woven fabrics or strips or by braiding.
5. The method of claim 1, wherein the textile fabric has edge protection along its edges.
6. The method of claim 1, whereby the woven fabric comprises warp and weft threads, in each case basalt fibers.
7. The method of claim 1, whereby roving and yarns with a fineness of 50 to 3000 tex, are used for the woven fabric and the woven fabrics produced form the yarns have a surface weight of 70 to 1500 gm2.
8. The method of claim 7, whereby roving and yarns with a fineness of 50 to 500 tex, are used for the woven fabric.
9. The method of claim 7, whereby the woven fabrics produced form the yarns have a surface weight of 90 to 200 gm2.
10. The method of claim 1, whereby the woven fabric comprises several coats or layers and is fastened mechanically in terms of weaving technology with quilting seams, whereby the quilting seams are executed using a sewing cotton.
11. The method of claim 1, whereby the layers of the textile fabric are connected to one another by means of adhesion technology.
12. The method of claim 11, wherein the layers of the textile fabric are connected to one another by means of welding adhesive tape andor by means of adhesive powder.
13. The method of claim 1, whereby the textile fabric material comprises yarns or multiyarns.
