MECHANICAL WAYS:

- use of gravity for moving from a higher to a lower position;
- mechanical pump that puishes fluid in or out;
- mechanical pump that uses suction and pulls fluid in or out (e.g. with the help of Bernulli effect);
- turbine pumps (Archimedes screw);
- centrifugal pump;
- peristaltic pump;
- progressive cavity pumps;
- mecahnical pump where instead of pistons "shape memory alloys" are used;
- air pump which uses air instead of pistons: when air is heated it expands and pushes liquid; when it is cooled it contracts;
- use of air bubble which changes volume depending on temperature;
- use of vapor of the liquid to propel it (e.g. by heating it or employing optical hydraulic effect, or lasers, etc.);
- use of low boiling fluid instead of air: when it is heated it expands and propels the fluid, which needs to be moved;
- use of solids which melt and expand at a certain temperature and thereby propel liquid; when heat is removed it solidifies again and contracts;
- PZT (piezo-electric effect) pumps where instead of pistons the pump chamber is built of piezoelectric material: when voltage is applied the chamber contracts and pushes fluid out;
- Magnetostriction pumps where instead of pistons the pump chamber is built of magnetostriction material: when magnetic field is applied the chamber contracts and pushes fluid out;
- micro-pumps that use thin film alloy microactuators;
- use of explosion to pump liquid;
- periodical increasing and decreasing hydrostatic forces by controlling the apparent density of the liquid;
- periodical increasing and decreasing hydrostatic forces by controlling the pseudo-viscosity of the liquid;
- periodical increasing and decreasing hydrostatic forces by employing Toms effect;
- use of Weissenberg effect to pump a liquid polymer;
- floatation: use of a liquid with a higher density to lift (and generally propell) a liquid of lower density;

PHASE TRANSITIONAL WAYS:

- distillation: vaporize liquid in one place, create the flow of vapor to the destination and condese the vapor over there;
- pressure swing distillation;
- extractive distillation;

CONVECTIONAL WAYS

Generate convectional flow by:
- creating a thermal gradient;
- adding flow induced substances to the liquid;

MOLECULAR WAYS:

- use of osmosis;
- use of diffusion;
- use of cell membranes;
- use of absortion;
- use of PCR (Polymer Chain Reaction) amplification;

ELETROMEGNETIC:

- electromagnetic pump for pumping conductive liquids;
- use of electrophoresis;
- use of capillary electrophoresis;
- use of electrohydraulic effect;
