The characteristics of hydrodynamic pumps

The design of pumps based on hydrodynamic fluid flow is proposed. In comparison to the frequently used gear pumps, hydrodynamic pumps are simple and cheap devices characterised with fluctuation-less delivery. Since the ratio of dimensions of hydrodynamic pumps seriously influence its efficiency, the proposed design is based on criteria of minimal friction loses.
